Its sole purpose is to help you understand the basic architecture of the OFM database and workspace so that you can correctly create your OFM projects. Learning Objectives At the completion of this module, you will be able to: • Describe the OFM data tables • Use the OFM Defined Table Manager • Create a Shared Workspace • Link a new Workspace to the Shared Workspace • Link an existing My Workspace to a Shared Workspace • Create a copy of a Shared Workspace. Schlumberger Public Lesson 1 OFM Database OFM can be viewed as having two integrated layers - database and application. Basically, the database layer handles the data part; and the application controls the user interface, as well as the processing data/information per request. OFM database is Microsoft Access-based. All data/information are stored in tables (and sometimes views). Therefore, OFM database has all the characteristics of a relational database, including constraints, keys, and indices. There are three main classes (types) of tables in an OFM database: • Data Table • System and Configuration Table • OFM -Managed Table There are two types of data tables in an OFM project: • Standard Data Tables that have no prefix • OFM Defined Data Tables that have OFM_Data_ as a prefix Previous versions of OFM also had OFM Defined System Data tables that had _OFM_SYS_ as a prefix. In OFM 2007 all the information that was stored in the OFM Defined System Data tables is now stored in the *.OFM workspace file. OilField Manager 2007 Fundamentals 7 Schlumberger OFM Basics NOTE: There are only two types of tables in OFM 2007, OFM-defined database tables having the prefix OFM_DATA_ and standard database data tables. Previous versions of OFM had tables containing the prefix _OFM_SYS_. All the information that was stored in those tables is now stored in the *.OFM workspace file. OFM Data Tables As the name suggests, these tables contain data. Most of the tables must have at least one key (primary key) and may contain constraint and indexing information. Each table has two or more fields, which have designated data types (i.e., date/time, number, or text) and size (i.e., long integer, double precision for number field, or 20 space wide for text field). By assigning the correct data types and sizes, you can assure no unexpected loss of data (in case of truncating, rounding-off) at load time. OFM data tables are not named with either the _OFM_SYS or the OFM_DATA_ prefixes. For example, a table to store time-independent data may resemble the image pictured below. Standard Data Tables NOTE: Standard Data Tables are tables that do not have the OFM_DATA_ prefix. In the above example, the UNIQUEID field is a text field that is 20 characters wide. In addition, it is designated as the primary key field in this HEADERID table (indicated by the key icon in the left). Also, as it is the primary key of the table (and later you will know that it is the master key of the OFM project) it carries additional properties (seen in the lower section, General tab). Please reference Relational Database concepts for further information. 8 OilField Manager 2007 Fundamentals Schlumberger Public A standard data table is any table that does not have the OFM_DATA_ prefix. The table must have a primary key and may contain constraint and indexing information. Each field in the table will have designated data types, i.e., date/time, number, or text and size, i.e., long integer, double precision for number field, or 20 spaces wide for text field. Assigning the correct data types and sizes will insure no unexpected loss of data from truncation or rounding at load time. For example, a table to store timeindependent data is shown in the following image. Schlumberger OFM Basics In the image below, the HEADERID table is the master table for the OFM project, as indicated by the key icon to the left of the table name. There are many fields in this table that are number (numeric) fields. For example, if you select the XCOOR field from the list, you would see the following: Schlumberger Public The UNIQUEID field is a field within the HEADERID table of type text that has a size of 20 and is designated as the primary key field in the HEADERID table, as indicated by the key icon to the left of the field name in the OFM Representation box and in the Attr column in the Available Fields box. NOTE: Not all field properties are displayed by OFM in the Available Fields section. To view any additional field properties open the table in Access in Design view and select the field. The additional properties will be defined on the General tab. The XCOOR field is a number field, with double precision and no decimal place assigned in display. Also, it is not indexed and can accept a null value. OilField Manager 2007 Fundamentals 9 OFM Basics Schlumberger In the following image other field types can be seen in the HEADERID table. For example, the YCOOR field is of type Double, UPPERPERF is of field type Single, and COMPLETIONDATE is of field type Date/Time. By design, OFM requires the designation of a MASTER table, which normally stores static well information such as Well Alias, Well Coordinates, etc… The primary key of this master table is the main (MASTER) key of the whole OFM project. HEADERID table in the above example is a master table. To create a project OFM requires that a table be designated as the master table and that a field in the master table be designated as the primary key for the project. In the previous images the HEADERID table is the master table and the UNIQUEID field is the primary key. The master table contains static data about the primary key. The primary key is usually the completion name and the table would contain static data like the completions XY coordinate, alias, completion date, total depth, etc. Many other data tables may contain more than one keyed field. For example, a date-dependent table must have at least two keys: one is the entity key (similar to the UNIQUEID key); the other is the date key. Now take a look at a monthly frequency table. 10 OilField Manager 2007 Fundamentals Schlumberger Public When the field is a number, assigning the appropriate field type will save space in the database. Schlumberger OFM Basics An OFM project can consist of many table types. Some table types contain more than one keyed field. For example, a monthly or daily table, which is date dependent, would have two keys: the primary key and a date/time key. In the following image a monthly table is highlighted. Schlumberger Public As seen above, this MONTHLYPROD table has two keys. The UNIQUEID key joins this MONTHLYPROD table to the HEADERID table, in a relational manner. However, the primary entity key of one table does not have to be identical to the primary entity key (master key) of the OFM project. As long as a relationship (join) can be established between the two tables (normally via an intermediate field – could be a foreign key), there is no violation in the design of the OFM database. For example, if you have a table like this: This can be joined to the HEADERID table as long as there exists a way to relate Reservoir (in this RES_PROD table) to the OilField Manager 2007 Fundamentals 11 Schlumberger OFM Basics UNIQUEID field in the HEADERID table. In this illustrative database, there is a table that contains such valuable information. The relationship between them could be established as shown below. NOTE: You do not have to physically make the joins between the tables. Exercise 1 NOTE: There is a special type of data table named *_Adjustments in the Access database. These tables store prior cumulative production for the respective date-dependent tables. For example, open the Demo2007.mdb database with Access, the MONTHLYPROD table will have an adjustments table named MONTHLYPROD_Adjustm ents. The instructor will explain why this special table type may be needed. Exploring Other Data Tables Explore the DAILYPROD, TEST and CHOKE tables in the Demo2007.mdb database. • How many keys are there in the CHOKE table? • Which key is the primary key? The instructor will explain why the CHOKE table is a special type of table in OFM. OFM Defined Data Tables The other type of table in OFM is the OFM-defined data table. It stores data that is either loaded, input or a result of OFM analyses. One type of OFM-defined data table has the prefix OFM_DATA_DCA_ and decline curve analysis data generated in the OFM decline curve analysis module. These tables are automatically created when the project is created and will not contain any data unless a forecast has been saved or merged from another workspace. The names of these tables, as defined by OFM, cannot be changed. Some additional OFM defined data tables are OFM_DATA_Deviation, OFM_DATA_Fault, OFM_DATA_FILTER, OFM_DATA_Log, OFM_DATA_Marker, etc. It is not recommended that the names of these tables be changed as it could prevent OFM from being able to access the 12 OilField Manager 2007 Fundamentals Schlumberger Public The data tables store data that have got loaded into the project. Please take a look at a few data tables to experiment. Schlumberger OFM Basics data. Even though OFM-defined data tables are basically data tables, the data that are stored in them can be sensitive to changes; therefore, it is not recommended that the data be manipulated manually. Exercise 2 Studying OFM Defined Data Tables Using Microsoft Access, open the Demo2007.mdb database and study the OFM-defined data tables. The OFM Defined Table Manager NOTE: Refer to Lesson 2 for more information on My Workspace and Shared Workspace concepts. OilField Manager 2007 Fundamentals 13 Schlumberger Public The Database\Schema Tables… option is now used to only edit standard data tables. The Database\OFM Defined Tables… option has been added to manage all of the OFM-defined data tables. OFM-defined data tables are tables with the OFM_DATA_ prefix. They consist of Decline Analysis, Deviation, Fault, Log, Marker, Pattern, PIPESIM, PVT, and Wellbore Diagram tables. OFM-defined data tables now can be switched between Shared Workspace and My Workspace. If the OFM-defined data table is pointing to Shared Workspace then it is read-only. The OFMdefined data table has been converted to an entity based sporadic table. NOTE: The Log table (i.e., OFM_DATA_LOG) stores binary data object (i.e., BLOB). Therefore, the data (trace values) cannot be edited in this table. Schlumberger OFM Basics Lesson 2 OFM Workspace The following eight system tables were removed from the Access database: NOTE: There are three types of OFM-defined tables which have the prefixes _OFM_SYS_, OFM_DATA_ and OFM_DATA_DCA_. • _OFM_SYS_Configuration • _OFM_SYS_DateRange • _OFM_SYS_FieldProp • _OFM_SYS_Multipliers • _OFM_SYS_Parser • _OFM_SYS_TableInfo • _OFM_SYS_TableMap • _OFM_SYS_Units. NOTE: If the project was a OFM2007 project and had an existing *.OFM workspace the default setting in OFM 2007 is to backup the *.OFM workspace file and is recommended. If the project was a *.mdb project created with OFM 2004 or earlier then the backup message will not display and all the information in the eight system tables will be written to the OFM 2007 *.OFM workspace file. 14 The second step was to remove the remaining seven tables having the prefix _OFM_SYS_, i.e., System tables, from the Access database. This step occurred in OFM 2007. When any project created in a previous version of OFM is opened with OFM 2007, the information that originally resided in the eight system tables is written to the OFM 2007 *.OFM workspace file. If the project was created in OFM 2004 or earlier, then the information is taken from all eight system tables. If a project was created with OFM 2005 or upgraded to OFM 2005, then the information is taken from the OFM 2005 *.OFM workspace and all the system tables except the _OFM_SYS_Configuration table, which would only exist if the project had be upgraded to OFM 2005 and would not exist if the project was created with OFM 2005. The system files in any project created in a previous version of OFM become obsolete when upgraded to OFM 2007. OilField Manager 2007 Fundamentals Schlumberger Public The first step taken was to extract all the information stored in the _OFM_SYS_Configuration table and put it in a HTML file with the suffix *.OFM. When any version of OFM 2007 is used to open a *.mdb project created with OFM 2004 or earlier, a XML file with the suffix *.OFM is created and the information from all eight tables with the prefix _OFM_SYS_ is written to this file not just the _OFM_SYS_Configuration table. This *.OFM file is referred to as the OFM workspace file. The _OFM_SYS_Configuration table is not deleted from the Access database and can be used to restore the *.OFM workspace file to the configuration it had when the project was converted if the *.OFM workspace file should ever become corrupt, however, any changes to the project configuration that occur after the project is converted are stored only to the *.OFM workspace file; the _OFM_SYS_Configuration table becomes obsolete. Schlumberger OFM Basics About Shared Workspace / My Workspace In OilField Manager 2007 (OFM 2007) the Private Database functionality has been replaced with the functionality to create workspaces. There are two types of workspaces – Shared Workspace and My Workspace. When a workspace is a standalone workspace or a workspace linked to a data source the items in the workspace will be referenced using the word My. The main folder in the Analysis pane will be My Analysis, the main folder in the Calculated Variables window will be My Calculated Variables, the main folder in the Categories window will be My Categories, the main folder in the Units window will be My Units, etc. When the word My is used, that means that the items can be edited. When a workspace is linked to another workspace, the items in the workspace will be categorized as either My or Shared. Any items that are categorized under the word Shared will not be editable from within that linked workspace. Creating a Shared Workspace In your training data set is an Access database named Company Data Source.mdb. The following workflow will create a Shared Workspace that is linked to the Company Data Source.mdb file. The Shared Workspace will then be linked to, illustrating how a user would access the Shared Workspace using the Shared Workspace / My Workspace concept. In this example the external data source is an Access database but it could be any external data source, Oracle, SQL, Excel, etc. OilField Manager 2007 Fundamentals Schlumberger Public A Shared Workspace can be a standalone workspace or a linked workspace. A typical Shared Workspace can be a workspace linked to a company database or a standalone project created using ASCII files. The primary benefit of a Shared Workspace is the ability to share a project with multiple users while restricting those users from modifying shared files. The functionality to create a shared workspace is the same as with OFM 2005 or OFM 2004, using linked tables or ASCII files. The only difference is once the workspace is created the items in the Shared Workspace will be referenced using the word My, as in My Analysis, My Calculated Variables, My Categories, etc. If you link to the Shared Workspace using the Link to a Shared Workspace File: functionality, you will see the same items referenced using the word Shared; the items in the users linked workspace just created will be referenced using the word My. You will be able to add, edit or delete any of the items referenced as My, but will not be able to add, edit or delete any of the items referenced as Shared. NOTE: In OFM 2007.1 the word Team was used. It was replaced in OFM 2007.2 with the word Shared. NOTE: The procedure which follows would be performed by a nominated Owner of the Shared Workspace, typically a Team Leader or some other responsible person in the organization. 15 Schlumberger OFM Basics 1.

Click Select All to map all the tables to the project using the same workflow as in OFM 2004 or OFM 2005. The Shared Workspace.mdb database and Shared Workspace.OFM workspace file represent a workspace that is to be shared by multiple users. The users would access the Shared Workspace using the Link to a Shared Workspace File functionality. This functionality will be illustrated next but first let’s add some output to the Shared Workspace.OFM workspace file making note that everything created or currently referenced in this workspace uses the word My, as can be seen in the Analysis pane where the folder is named My Analysis. NOTE: All the analysis items created are placed in folders that are referenced using the word My. That means that anyone with access to the Shared Workspace.OFM workspace file can potentially open the workspace file and add, edit, or delete any of the items in the workspace. To prevent unauthorized users from accessing the shared workspace, it needs to be secured from those users. 13. Select Analysis > Report. The Edit Report window displays. Create a report and from the Analysis pane rename the report Shared_Report. 14. Select Database > Calculated Variables. The Calculated Variables window displays. Create a calculated variable name Shared_CV. OilField Manager 2007 Fundamentals 19 Schlumberger OFM Basics Creating a New My Workspace that is Linked to the Shared Workspace The Shared Workspace enables you to share the workspace, but prevents you from being able to add, edit, or delete items in the workspace. We are now going to simulate how a team member would create a new personal workspace, and how he will link to the Shared Workspace created during the previous exercise in order to share all of its items. 1. To create My Workspace open OFM 2007. 2. Select File > New Workspace. The New OFM Workspace window displays. 3. Click the browse button to the right of the Workspace File field. The New OFM Workspace window displays. 4. In the File Name field, type My Workspace and click OK. You are returned to the New OFM Workspace window.

Schlumberger OFM Basics 10. Right-click on the Shared_Bubble_Map and select Save As New Node. The bubble map can be copied to the My Analysis folder. Rename the bubble map My_Bubble_Map. Schlumberger Public 11. Select Database > Calculated Variables. There is a My Calculated Variables folder and a Shared Calculated Variables folder. 12. Expand the Shared Calculated Variables folder. The Shared_CV variable previously created is available. 13. Select Company_CV and right-click. Note that the only selection for you is to copy the calculated variable. Add, edit, or delete options are not available. 14. Right-click on Company_CV and select Copy. OilField Manager 2007 Fundamentals 21 Schlumberger OFM Basics 15. Click OK. Enter My_CV as the name for the new calculated variable. The variable is listed below the My Calculated Variables folder. 16. Close the Calculated Variables window. Linking an Existing OFM Project Workspace to a Shared Workspace There will be times when you may wish to migrate a pre-existing OFM 2005 project, complete with your pre-existing (standalone) associated My Workspace, to OFM 2007. In the previous exercises you were creating new Workspaces. Here, however, you will retain an existing Workspace, but make use of the new Shared Workspace feature in OFM 2007. To do this, use the Database > Shared Workspace facility. To link an existing workspace to a Shared Workspace: 1. Open the Demo2007 project as a standalone user: Select File > Open Workspace. Navigate to the My Workspace file you created in the previous exercise. 2. The project opens, with the Analysis pane indicating that only one Workspace, My Workspace, exists. This is the situation that would have existed when you were an OFM 2005 user. 22 OilField Manager 2007 Fundamentals Schlumberger Public It is important to review and note that previously a workspace was created that was to be shared to other users. Upon opening that workspace directly you will see the word My on all the items because it is a standalone project that was created with ASCII files or is linked to an external data source. When you create a My Workspace that is linked to that Shared Workspace will see Shared on all the items in the workspace previously created and My on all the items created in the My Workspace just created. The items are labeled as My or Shared depending on from which workspace they are being viewed. Schlumberger OFM Basics 3. Select Database > Shared Workspace. The Shared Workspace form opens. Now navigate to the Workspace file, which will represent the Shared Workspace to which you wish to Link. 4. Click Add. Schlumberger Public 5. Navigate to Shared Workspace.OFM and click Open. 6. OFM offers you the option to rename this Shared Workspace. (Remember, you may choose one of several Workspace files to be the current Shared Workspace.) 7. If you wish to accept the default, click OK. 8. You then return to the Shared Workspace form, which displays the list of available Shared Workspaces. Check the OilField Manager 2007 Fundamentals 23 Schlumberger OFM Basics box next to the one that you wish to make the current active Shared Workspace and click OK. At this point, OFM issues a message: Schlumberger Public IMPORTANT: OFM is about to perform the linking process. Any Table, Calculated Variable, Category, Unit or Multiplier in YOUR My Workspace that has the same name as one in the Shared Workspace will be considered to be a duplicate and will be removed from My Workspace. You should consider this before performing the link process. If you suspect that any such element (e.g., a personal calculated variable) may suffer from this duplication removal, rename it before you start the link process to ensure that your calculated variable survives. 9. Once you are satisfied, click OK. Your OFM session should now display an Analysis pane with two Workspaces: your pre-existing Workspace (My Workspace) and the newly linked Shared Workspace (Shared Workspace). Creating a Standalone Snapshot of a My Workspace and its Shared Workspace This feature enables you to combine My Workspace and any Shared Workspace that it is connected to into a single My Workspace that will contain all the items and data from an original My Workspace and the Shared Workspace that it was connected to, including linked tables. All the items in the Standalone Snapshot will be referenced with the word My and can be edited. 24 OilField Manager 2007 Fundamentals Schlumberger OFM Basics 1. To create a Standalone Snapshot, select Database > Workspace Snapshot. The Workspace Snapshot window displays. 2. Click the browse button to the right of the Workspace File list field. 3. The Open window displays. Schlumberger Public 4. Type Snapshot in the File name list field and click Open. 5. Click OK. The Workspace Snapshot window closes. OilField Manager 2007 Fundamentals 25 Schlumberger OFM Basics 6. Open the newly created workspace Snapshot.OFM. In the Analysis pane the Share_Report, the Shared_Bubble_Map, the My_Report, and the My_Bubble_Map have been combined into a single My Analysis folder, as shown below. NOTE: All the items in the Snapshot.OFM workspace can be edited by the user. The snapshot could be sent to a co-worker, a partner company who shares interest in the project or to Schlumberger support for troubleshooting purposes. 8. Close the Snapshot.OFM workspace. 26 OilField Manager 2007 Fundamentals Schlumberger Public 7. Select Database > Calculated Variables. Both the Shared_CV and the My_CV will have been combined into just a single My Calculated Variables folder, as shown below. Schlumberger OFM Basics Creating a Copy of the Shared Workspace This option enables you to generate a copy of the Shared Workspace. This feature is useful when you need to work but will not have access to the Shared Workspace. You can make a copy of the Shared Workspace and take it with you to perform your work then reconnect to the original Shared Workspace later time. 1. To create a copy of the Shared Workspace that the My Workspace is linked to open the My Workspace.OFM file. Select Database > Workspace Snapshot. The Workspace Snapshot window displays. 2. Click the browse button to the right of the Workspace File list field. The Open window displays. 3. Enter Copy of Shared Workspace as the file name and click Open. 4. Select the Create a copy option, as shown below, and click OK. Schlumberger Public 5. Click OK. Close the My Workspace.OFM file and open the Copy of Shared Workspace.OFM file. OilField Manager 2007 Fundamentals 27 OFM Basics Schlumberger The data and information will be the same as the original Shared Workspace.OFM file up until the date the snapshot was taken. Schlumberger Public 28 OilField Manager 2007 Fundamentals Schlumberger OFM Basics (Optional) Migrating an OFM 2004 Database to OFM 2007 The procedure below provides detailed instructions on how to migrate an OFM 2004 database to OFM 2007. 1. Select File > Open Workspace. The Open OFM Workspace window displays. 2. From the Files of type list field, select OFM2004 Projects (*.mdb). 3. Navigate to the location of the *.mdb file you want to load. Schlumberger Public 4. Select the file name and click Open. 5. A confirmation dialog displays enabling you to confirm that you wish to convert the OFM project. 6. Click Yes. A second confirmation dialog displays prompting you to confirm if you wish to use the HEADERID as the OFM master table. 7. Click Yes. The Edit Schema Tables dialog displays. OilField Manager 2007 Fundamentals 29 Schlumberger OFM Basics Exercise 3 Opening an OFM Workspace To open an OFM workspace: 1. From the File menu select Open Workspace. The Open OFM Workspace window displays. Exercise 4 Changing the Database In this exercise you will re-attach the workspace to a new project (database), while still retaining the properties contained in the workspace file. 1. From the Database menu select Change Database. The Open dialog displays. 2. Navigate to the location of the desired database, select the file and click Open. The basemap displays. 30 OilField Manager 2007 Fundamentals Schlumberger Public 2. Select the name of the file you wish to load and click Open. The basemap loads in the OFM main window. Schlumberger Exercise 5 OFM Basics Changing the Well Symbol Size In this exercise you will modify the well symbol size. Change the well symbol size to 1.5. 1. Select Edit > Map >Symbols. The Well Symbols dialog displays. Schlumberger Public 2. Locate the Size section and change the Value to 1.5. 3. Click OK. OilField Manager 2007 Fundamentals NOTE: If you need clarifications, please do not hesitate to ask your instructor. 31 Schlumberger OFM Basics Exercise 6 NOTE: Notice that the basemap header, well symbols, and the plot template are on the workspace level, independent of the database. This is the advantage of having created a workspace that pulls data from various identically designed databases. In this exercise you will change the database in a workspace. 1. Select the Base Map1 from the Analysis pane. From the Database menu, select Change. 2. Locate the Training directory and go to Buildit2. Select Waterflood.mdb. Click Open. 3. Notice how the size of the well symbols has been adopted from the settings saved in the workspace file. Exercise 7 Reversing the Changes 1. Change the database back to Demo2007.mdb. 2. Resize the well symbol from 1.5 back to 1. Schlumberger Public NOTE: If you choose to create a brand new database at project creation time, you will have to populate the data in the next steps (after Step 5). OFM supports various methods of “loading” data to the OFM project, such as using the Data Loader. The next section demonstrates such functionalities. Changing the Database in a Workspace Review Questions • What are the names of the data tables used in OFM and what is the purpose of each one? • What is the purpose of the OFM Defined Table Manager? • What is the benefit of using a Shared Workspace? • Why would you want to link My Workspace to the Shared Workspace? • When is it useful to create a copy of a Shared Workspace? Summary In this module, you: 32 • Familiarized yourself with the OFM database and OFMdefined data tables • Reviewed the OFM workspace • Learned the basics about the Shared Workspace and My Workspace concepts • Created a Workspace Snapshot OilField Manager 2007 Fundamentals Schlumberger • Copied a Shared Workspace • Migrated an OFM 2004 database into OFM 2007. OFM Basics In the next module, you will learn how to create and associate data with OFM projects. Schlumberger Public OilField Manager 2007 Fundamentals 33 Schlumberger OFM Basics NOTES Schlumberger Public 34 OilField Manager 2007 Fundamentals Schlumberger Project Creation Module 2 Project Creation In this module, we will cover the most common ways to create and get data into an OFM project. The structure of the project should be carefully designed before actually launching the first creation step. Data cannot be lost or changed by specifying incorrect tables. If a project table does not match the data source the data will simply not load or will not be viewable but nothing will happen to the data. Prerequisites Before getting to the actual data populating exercises, it would be useful to understand the OFM data table types and specifications. Learning Objectives In this module you will learn to: Analyze table types • Populate project with ASCII data files (OFM formats) • Populate project with ASCII data files (PI/Dwights formats) • Link the project with data from external ODBC sources. Lesson 3 Schlumberger Public • OFM Table Types OFM data are stored in Microsoft Access tables, which follow relational database design concepts. In addition, OFM tables have their own constraints and properties. Understanding the table structures in order to correctly construct the project will save you time and also guarantee the normal behavior and data integrity of your created project. OilField Manager 2007 Fundamentals 35 Schlumberger Project Creation The following summary table provides information about the most commonly used OFM tables: Table Type MASTER Key Types Key Data Types Entity 1 Entity DAILY 2 Entity Date Date Entity Date Date Entity Prm. Key Num/Date Entity Prm. Key Sec. Key Num/Date Num Entity Name Date Text Date Entity Name Text HOUR MINUTE SECOND SPORADIC 2 2 SPORADIC DUALKEY 3 LOG 3 MARKER 2 Comments MUST also be of STATIC type. The master (entity) key (also called completion) is preferably Text (String) The key could be either completion or foreign key At most 1 record per day per entity. At most 1 record per month per entity (day value is not considered) At most 1 record per day per entity Intra-day records per entity are allowed Entity key MUST be Wellbore.

Name key is the marker name. Schlumberger Public XREF (cross reference) Lesson 4 Key Data Types Project Creation An OFM project can be defined/created using a variety of methods: • Creating it directly from an Access database • Using a template • Designing it interactively using linked tables • Creating it from a data source like ASCII Flat Files, OFM3 Project Database or PI/Dwights • Linking to a shared workspace file. In the next section you will define/create a project using ASCII Flat Files, PI/Dwights DMP2 Production files, an Access database, and Linked Tables. OilField Manager 2007 Fundamentals 37 Schlumberger Project Creation Lesson 5 OFM Loadable ASCII Flat File Formats In this section, you will learn the formats of OFM loadable ASCII Flat Files for various table types. You will then create a new OFM project from the text files (provided in the installed program directory). You MUST load the definition file and the (master) key data file (in that order) first. Most of the ASCII data files do not have to be loaded into your OFM project in order. Load the table definition file (for one or many tables) before loading the data files for those tables. If you choose to create the tables interactively (without using the definition files), they MUST exist before the data files can be loaded. This is also true if you want to load data into a group table (different entity key than the key in the master table), as you must define that group entity before OFM can load the data. For example, if you want to load production data at the reservoir level into a table called RES_PROD, the reservoir entity has to be associated (as a sort category, a foreign key, a wellbore, etc.) before load time. The table definition for that table also has to be created beforehand. *.def – table definition file Multiple data files can be loaded into one table (appending). *.xy – master (key) data One definition file can hold information of one or more tables. *.dly – daily frequency data Multiple files (definition and data) can be loaded into the project at the same time. *.srt – sort category data *.prd – monthly frequency data *.tst – test (sporadic) data *.lku – lookup data *.xrf – cross-reference data *.par – parser (i.e., calculated variable) data *.dev – deviation data *.not – note (i.e., plot annotation) data *.flt – fault data *.log – log (trace) data *.mrk – marker data *.wbd – wellbore diagram data *.pat – pattern data *.ano – map annotation data 38 OilField Manager 2007 Fundamentals Schlumberger Public TIP: Most of the time, each data file contains information from only one table. OFM automatically recognizes the table types if the text load files have some specific extensions. If the data files don’t have the commonly used extensions that OFM expects, they will be treated as typical data files, and will be parsed into the specified tables. Here are some commonly used file extensions: Schlumberger Project Creation We have constantly used the terms definition file and data file. Not all the tables in OFM require table definitions before load time. These are tables that do not require table definitions before load time: • Deviation table • Fault table • Marker table Sort category (filter) table • Pattern table • Wellbore diagram table • Parser table* *Parser table is not a typical table in many ways, even though parser information does get stored in a table. Viewing the (ASCII) Text Load Files Schlumberger Public OFM does expect the text files to follow certain file formats so that it can read and write the data to the database correctly. The files have to contain keywords to designate/separate all information stored in the files. A comprehensive list of all keywords can be searched from the on-line help file provided with the application. In this procedure, you will study the characteristics of some important table definition and data files in the Demo (usually located in the \\…\Sample Databases\Demo Database\Text Load Files\ directory, where \\…\ denotes your installed OFM program directory). 1. Launch a text editor such as Notepad or WordPad. (If you have already associated the application with the file extension, you can open the file directly from Windows Explorer). 2. Select File > Open. 3. The Open Window displays, select All Files or All Documents from the Files of Type drop-down list. 4. Locate the \Sample Databases\Demo Database\Text Load Files\ from your program directory. 5. Select Demo Definitions File.def. OilField Manager 2007 Fundamentals 39 Schlumberger Project Creation 6. Click Open. The definition file displays, as shown below (partial file only): Schlumberger Public Notes: 40 • The row beginning with the *Tablename keyword defines the table name, table type and indicates that it will be the master table. The file format is space delimited so whatever text lies between the next two spaces, consecutive spaces are treated as one, will be the name of the table, followed by the table type and the master table designation. • In this example HEADERID is the table name and it is a static table and most importantly it is the master table. A project can have as many static tables as desired, but there can only be one master table. • In the fields/variables section, each field is assigned a data type, text or numeric (with size). As many other PC applications, OFM has several precision specific numeric types such as INT2, FLOAT, DOUBLE, etc … • In the definition file, the field’s attributes can be assigned, identified by the keywords such as *pn for Plot Name, *pa for Plot Attribute, *u for Unit, and *mu for Multiplier. These attribute keywords can be searched from the help file. OilField Manager 2007 Fundamentals Schlumberger • Project Settings keywords may appear in the definition file. *DateLabel is one of them, denoting the displayed DATE name for the project. For example, a Spanish speaking user can select to use FECHA for date; the user has to insert *DateLabel FECHA at the top of this definition file. Another Project Settings keyword you may see quite often is *Metric, which alerts OFM to treat the project as in Metric unit system. • The static master table must be the very first table defined in the primary definition file (there may be many multiple definition files). • If the table name, variable name, or even the attribute contains two or more words and has space(s) between them (or non-ASCII characters), they should be enclosed in quotes (for instance, MY WELL) for OFM to treat it properly. • Comment lines have to be started with either comment identifiers // or /*. These lines are just descriptive information and will be ignored by OFM at load time. All texts are case-insensitive. Project Creation OilField Manager 2007 Fundamentals Schlumberger Public Now take a look at the definition of the monthly production table named MONTHLYPROD. Scroll down the file and locate the line *TABLENAME MONTHLYPROD Monthly. Notice the structure of the definition file. 41 Schlumberger Project Creation In this case, MONTHLYPROD is the name of a MONTHLY table, which has fields like DAYS (an int4 type), OIL (a float type), and more. 7. Continue to scroll up and down the definition file to study other tables, their fields and attributes. Notice the CHOKE and the RES_PROD tables. The CHOKE table is a DUALKEY SPORADIC table. Therefore, the *DUALKEY keyword is required after the *Tablename line. Likewise, RES_PROD is a GROUP level table. OFM needs to know at which level its data are associated. Thus, the word GROUP is required, followed by the group name. In this case, it is RESERVOIR (a Sort Category). TIPS – NUMERIC SIZE Numeric Type Value Ranges: INT1: -128 to 127 • INT2: -32,768 to 32,767 • INT4: -2,147,483,648 to 2,147,483,647 • UINT1: 0 to 255 (unsigned int1) • UINT2: 0 to 65,535 (unsigned int2) • UINT4: 0 to 4,294,967,295 (unsigned int4) • FLOAT: occupies 4 bytes, 7 decimal places, and values of approximately -3.4E-38 to 3.4E38. • DOUBLE: occupies 8 bytes, 19 decimal places, and values of approximately -1.7E308 to 1.7E308. • Knowing the appropriate range of your variable data and assigning the proper size to the variable may help you save memory and improve performance. TIPS - Reserved Keywords There are reserved keywords that may be used in the text load files. They have special meanings to OFM and cannot be reused as variable names. The following table is a list of the most commonly used reserved keywords: *DateLabel *Day *DD *DDMMYY *Define *Depth *End_Define *EOF *End_Format *Format 42 *KeyLength *KeyLimit *KeyName *Metric *MM *MMYYDD *Month *Null *Quiet *ReadOn *ReadOff *Skip *TableName *TVD *XDelt *YDelt *Year *YYMM *YYMMDD OilField Manager 2007 Fundamentals Schlumberger Public • Schlumberger Project Creation Analyzing Data Files The procedures below will assist you in analyzing static data, monthly data, daily data, hourly data and sporadic data. Static Data To begin analyzing static data follow the instructions below. 1. Launch any text editor. 2. From the File menu select Open and navigate to the Demo Key Data.XY file located in the Text Load Files directory. Schlumberger Public Study the file (please scroll to the right to see all field data). The variable identifiers exist before the data section, right below the *tablename line. OFM parses data into the corresponding fields, based on the order they appear on that variable identifier's line. Monthly Data To begin analyzing monthly data, follow the instructions below. 1. From the open text editor select Open. 2. Navigate to the Demo Monthly Prod Data.prd file. OilField Manager 2007 Fundamentals 43 Schlumberger Project Creation Notice the *KeyName line. This tells OFM which entity the next data section will be loaded into (until the next instance of *KeyName). 3. Scroll down to see the rest of the file. Daily Data To begin analyzing daily data follow the instructions below. 1. From the open text editor select Open. 2. Navigate to the Demo Daily Prod.dly file and view the data. To begin analyzing hourly data follow the instructions below. 1. Export the Hourly data to notepad. 2. Select Database > Export > Selected Text Load File(s) > Table Data. The Table to Export window displays. 44 OilField Manager 2007 Fundamentals Schlumberger Public Hourly Data Schlumberger Project Creation 3. Select HourlyProd and click OK. The Save As dialog displays. 4. Navigate to the desired save location and click Save. 5. Open the HourlyProd.hly file and view the data. Sporadic Data 1. From the open text editor select Open. OilField Manager 2007 Fundamentals Schlumberger Public 2. Navigate to the Demo Sporadic Test Data.tst file and view the data. 45 Schlumberger Project Creation The Sort Category table is a non-defined table. The table definition is specified at the beginning of the file, between the *Define and the *End_Define keywords. In OFM 2007 (as well as in any versions after 2002), it is not mandatory to physically have a Sort Category table in the OFM project. Any field, preferably a text field, from a static table can be used as a category. Refer to the Editing Sort Categories section for additional information. Study Other Text Format Files Continue to study the other text file formats in the \…\Text Load Files\ directory. Exercise 8 Creating a Project from ASCII Text Files In this section, you will learn to create a new project with text files provided in the Demo Text \Load Files directory. 1. Start OFM. 46 OilField Manager 2007 Fundamentals Schlumberger Public There are additional text load files provided with the Demo project. With the help of the instructor, you are encouraged to become familiar with those files, especially the typical format of each file/table. Schlumberger Project Creation 2.

Create the files listed below for a simple four-well project. • One definition file • One key data file • One monthly production file • One daily production file for a simple four-well project 2. Create a new workspace and load the files to the project. Exercise 10 Using Batch Loading (optional) WARNING: Before proceeding check your OFM installation directory for the *.bdl and the *.bpf files. If you do not have these files, ask your instructor to get a sample copy. There are two types of batch data loading in OFM. One is used for loading multiple files to create a project, the other loading multiple files to create multiple projects. The former batch file should have the *.bdl (e.g., Batch Data Loading) extension, and the latter should have the *.bpf (e.g., Batch Project File). This exercise demonstrates how to use the first feature. 1. Open the *.bdl (for example, Batch Data Load File.bdl) in a text editor. 2. If needed, edit to verify the path/directory of the text files is correct. In this case, it would be \\…\…\Text Load File\ and then the full file. 3. Verify that the definition and key data files are the first two files in the list. 50 OilField Manager 2007 Fundamentals Schlumberger Public Exercise 9 Schlumberger Project Creation 4. Repeat steps 1- 7 of the Creating Project from ASCII Text Files exercise. 5. Locate the Batch Data Load File.bdl file and click Add. OFM reads the file. 6. Place the correct specified files into the Files to Load list (in the specified order). 7. Click Load to load the files as you did in the previous exercise. 8. The project keyword line is followed by those lines (data files) seen in a *.bdl file. A different project is identified by a new *project line, then its own data files. To execute this batch loading procedure, from the File menu with no workspace opened, select Batch Load and the desired file to load. 9. Verify the path and file names are correct to guarantee correct loading of data. NOTE: The format of the *.bpf is similar to the format of the *.bdl file, except for each project, there is a line specifying the project name and directory. For example, a project named DemoData in the D:\Temp directory is specified as: *Project “D:\Temp\DemoData.mdb ”. Do not forget to close the workspace for the next exercise! Exercise 11 Creating a Workspace From PI/Dwights Production Files Schlumberger Public OFM provides a direct method to load certain PI/Dwights production files (i.e., dmp2, 298 fixed format) to create OFM projects.

Load a PI/Dwights 298 production file to the database. 3. Do not forget to close the workspace for the next exercise! Exercise 14 Creating a Workspace from an Existing Access Database If an Access database has tables that are compliant to the OFM database model, OFM can open it and generate a *.OFM workspace file so that OFM can utilize the data in the tables. If you open an Access database that does not comply with the OFM database model, OFM will attempt to open the database but may not be able to generate a *.OFM workspace from the data. In this lesson we will create an OFM workspace from an existing Access database. For training purposes, a simplified version of the Demo database will be used. Your generic Access database may resemble the image below. 1. Start OFM. 2. From the File menu, select New Workspace. The New Workspace window displays. 56 OilField Manager 2007 Fundamentals Schlumberger Public NOTE: OFM does not convert the Access database. Schlumberger Project Creation 3.

Select Yes to confirm that you want to make this Access database an OFM project. Schlumberger Project Creation The Edit Schema Tables dialog displays. NOTE: If your project has a composite key, you can specify the key by appropriate concatenation of the keys, with appropriate delimiter(s). Up to three keys can be combined to create the composite key field (denoted by Field1, Field2, and Field3 in the Table Key(s) group box). Also, you may have to customize a few things (map association, map properties, etc…) to properly display the basemap as desired. Exercise 15 Associating Tables to the Project Schlumberger Public In this exercise you will associate tables to the project. 1. Select the master (primary) key for this project in the Table Key(s) section of the dialog. In this case, the master key is UNIQUEID (which should have been selected for Field1). Click OK to proceed. The basemap displays. At this time, only the HeaderID table has been associated to the OFM project. The next step is to associate other Access tables to the OFM project. This is done from the Schema Tables window. OilField Manager 2007 Fundamentals 59 Project Creation Schlumberger 2. Select Database > Schema Tables. The Edit Schema Tables window displays, with all the tables available for OFM use. 60 OilField Manager 2007 Fundamentals Schlumberger Public 3. First map a STATIC table to the project. Use the vertical scroll bar to navigate through the Available Tables list and select SortCategory (by checking the box in front of the table name). The following message dialog displays, prompting you to confirm the addition of the SortCategory to the project. Click Yes. Schlumberger Project Creation You are returned to the Edit Schema window. Schlumberger Public 4. Locate the OFM Definition section of the window. Select Static from the Table Type list field.

Associate the rest of the available tables to the OFM project. 2. Do not forget to close the workspace for the next exercise! OilField Manager 2007 Fundamentals Schlumberger Public WARNING: You MUST uncheck the HeaderID alias field before checking SortCategory.RESERVOIR . Schlumberger Project Creation Exercise 18 Linking to an Access Database Considering that most Access databases are not created and maintained in an OFM-compliant manner combined with the common practice of keeping the original Access databases separate from the OFM project databases, OFM provides a dynamic method of linking the OFM database to the Access data source called the Linked Tables method. In this Linked Tables method, there are two separate Access databases – one containing the original data, i.e., the source, and the other containing the linked tables, the OFM Defined tables and any standard tables. Schlumberger Public The Linked Tables method can be used to connect to any ODBC(Open Database Connectivity) compliant data sources such as SQL Server, Oracle, or Microsoft Access, Microsoft Excel, etc… Its advantage is that the users always have a “clean” copy of the data. It reduces the risk of corrupting the original database. The trivial disadvantage of this method is the maintenance of two separate databases. In addition, each time the user requests data from the OFM project, the program has to resolve the links and goes to the source database to get data. This may add more time for data processing (especially when the source database is not located in the local hard drive and/or the source database is Oracle/SQL Server based), but at the same time guarantee the user always gets the most up-to-date version of the data. OFM provides built-in feature to connect to Microsoft Access. In this session, you will learn to create an OFM workspace linking to data from an external Access database. We are going to use the copy of the file Demo Access database that was in the previous exercise. 1. Start OFM. 2. From the File menu, select New Workspace. The New OFM Workspace window displays. OilField Manager 2007 Fundamentals 77 Project Creation Schlumberger 3. Click the browse button to the right of the Workspace File and navigate to the directory where you want your workspace file to be located. 4. Enter a workspace name, i.e., link_Access, and click OK. 78 OilField Manager 2007 Fundamentals Schlumberger Public 5. Leave the Database File name unchanged. Select the Design it interactively option. Schlumberger Project Creation 6. Click OK. The Edit Schema Tables window displays. 7. Locate the OFM Representation section of the dialog, select the HeaderID table, and right-click. A shortcut menu displays. 8. Select Delete from the menu options. Schlumberger Public OilField Manager 2007 Fundamentals 79 Project Creation Schlumberger The HeaderID key is removed from the Linked_Access node. 9. Click the Add Link Tables button. The Open dialog displays. Schlumberger Public 10. Locate the directory where your Microsoft Access source database is located. Select the database. 80 OilField Manager 2007 Fundamentals Schlumberger Project Creation 11. Make sure the Files of type box shows Microsoft Access (*.mdb). Click Open. The first table to link to the OFM project MUST BE the master table. In the source Access database, that table is the HEADERID. Schlumberger Public 12. Select the HEADERID table from the list and click OK. 13. OFM recognizes this table structure and suggests the key association. Click Yes to include HEARDERID in the project. OilField Manager 2007 Fundamentals 81 Schlumberger Project Creation 14. Since the mapping suggestion is correct, you do not have to take any action. Select the Linked_Access node from the left pane. 15. Click Add Link Tables. 16. Select the desired directory and database. Make sure Microsoft Access is selected as in step 5. Click Open. 17. From the Select Table(s) to Link dialog, click Select All. Notice that the HEADERID table is available for linking. You do not need to link the HEADERID table again. Therefore, while holding the Control key (Ctrl), click on the HEADERID table to unselect it. One source table can be linked as many times as you want. One source table is used to create many OFM project tables. Data from different external data sources can be linked to in a single OFM project. 82 OilField Manager 2007 Fundamentals Schlumberger Public NOTES: In step 12 of this exercise, you can select all tables by clicking Select All. You must then select the HEADERID table first from the Available Tables list to map into the project. Remember, the MASTER table must be mapped first. Schlumberger Project Creation 18. Click OK. The selected tables have been made available to the OFM project. Lesson 6 Schlumberger Public Project Creation – Linking to an Excel Spreadsheet Microsoft Excel has been used widely in the Oil and Gas industry to temporarily store data (before loading to long-term data management applications and/or analytical applications), as it is very easy to use. Excel is free formatted, which is error-prone for a relational database based application like OFM. OFM supports linking to Excel to get the data, via the Linked Tables method. However, to ensure the link between OFM and Excel works correctly, there are a few rules to consider: • The Worksheet Name will be used as the Table Name. • The first row on the worksheet is reserved for Field Names. These names should contain no spaces. • Data must begin in Row2, and every column with numeric data MUST contain a numeric value. Missing numeric data in Row 2 should be represented by the default null OFM value (-99999). • Each worksheet can only store data for one OFM table. No merging of worksheets allowed. • Data on the worksheet must be continuous. No empty row(s) should exist in between data sections. • No extra formats on the data columns (i.e., comments, merged cells, etc…). • Data in the same column must be of identical data type (i.e., number, text, date/time) and should be of the same format. • No embedded graphs allowed on the linked worksheet. In other words, KEEP IT SIMPLE! OilField Manager 2007 Fundamentals 83 Project Creation Schlumberger Exercise 19 Creating an OFM Project from an External Excel Spreadsheet Next we will create an OFM project with data from an external Excel spreadsheet. In order to achieve this task the Built-in Excel linking setup procedure is used and the data source is the stripped-down version of the Demo Access database. Obtain the Excel file from your instructor, or create one for this training exercise. The Excel spreadsheet structure resembles the images below. The first image depicts data in the Header table and second data in the Monthly table. Schlumberger Public 84 OilField Manager 2007 Fundamentals Schlumberger Project Creation Schlumberger Public To create an OFM project from an external Excel spreadsheet: 1. Launch OFM. 2. Create a new workspace. Locate the directory where you want to put the workspace file and the database file. 3. Select Design it interactively. Click OK. OilField Manager 2007 Fundamentals 85 Schlumberger Project Creation The Edit Schema Tables dialog displays. 5. Click the Add Link Tables button. The Open dialog displays. 6. Select the directory where the source Excel file is located. Select the desired file. From the Files of type drop-down list, select Microsoft Excel (*.xls). 86 OilField Manager 2007 Fundamentals Schlumberger Public 4. Locate the OFM Representation section of the dialog. Select the HeaderID table and right-click. A shortcut menu displays. Select Delete. Schlumberger Project Creation 7. Click Open. The Select Table(s) to Link window displays. 8. Click Select All, then OK. The Edit Schema Tables dialog displays. Schlumberger Public 9. Select the HEADERID table from the list. OilField Manager 2007 Fundamentals 87 Schlumberger Project Creation 10. Select the Link_Excel node. TIP: Right mouse click on the table (on the left pane) and select Rename from the menu, the program gives you access to changing table names. You can rename a table in OFM, once the table has been mapped. Many external tables have long names, which you may consider changing. The external table names are still unaltered; only the OFM table names change. The MASTER table can only be renamed when it has just been mapped to the project. After that, it cannot be changed. The other table names can be changed at any time unless the tables (and their children fields) are referenced by other tables/fields. It has been left as an exercise to associate all other Excel tables to the project now that they have already been made available for use. Exercise 20 Associating Additional Tables to the OFM Project TIP: There is one static table, one monthly table, one daily table, one sporadic table, one dual-key sporadic table, and one monthly foreign key. 88 1. Associate the other tables to the project. Refer to the previous two sessions if detailed instructions are needed, or ask your instructor for assistance. 2. Do not forget to close the workspace for the next exercise! OilField Manager 2007 Fundamentals Schlumberger Public Once you are connected to the external data source, the procedure to map/associate the external tables to the OFM project is identical and independent of the data source type. Schlumberger Project Creation Exercise 21 Advanced Topic: Linking to an ODBC Data Source (Optional) This lesson is designed to illustrate the Linked Tables method using ODBC driver setup. Usually, your ODBC data sources are not local. Connecting to such data sources requires a network connection and a driver – the DSN (Data Source Name). For training purposes, you are going to use a Microsoft SQL Server database as the ODBC data source. This SQL Server database is the upsized version of the Demo database (from Access). The simplified Demo Access database is used in this session. For further information about how to upsize your Access database to SQL Server, please consult with your instructor. 1. Launch OFM. NOTE: You can create the DSN prior to starting OFM, or you can create it during the project creation session. 2. Create a new workspace and a new database file in the desired directory. Select the Design it interactively option. Schlumberger Public 3. Click OK. The Edit Schema window displays. OilField Manager 2007 Fundamentals 89 Schlumberger Project Creation 4. Select the HeaderID table and delete it. Click the Add Link Tables button. The Open window displays. 5. From the Files of type drop-down list, select ODBC Database(). The Select Data Source appears. 90 Schlumberger Public TIP: It recommended that you create a Machine Data Source DSN. OilField Manager 2007 Fundamentals Schlumberger Project Creation 6. Select the Machine Data Source tab and click New. The Create New Data Source dialog displays. 7. Select the System Data Source option and click Next. Schlumberger Public 8. Since the data source is Microsoft SQL Server, select SQL Server from the list of available drivers. 9. Click Finish. The Create a New Data Source to SQL Server window displays. OilField Manager 2007 Fundamentals 91 Project Creation Schlumberger 10. In the Name field specify the Data Source Name. In the Description field, describe the data source. From the Server list field, select the host server name of SQL Server that you can connect to.

For more information, please consult with your instructor. 92 OilField Manager 2007 Fundamentals Schlumberger Public 11. Click Next. The wizard prompts you to enter the login information. Schlumberger Project Creation 12. Click Next. Select the default database where your source database is located and provide other information as needed. 13. Click Next and continue entering the connectivity specifications. Schlumberger Public OilField Manager 2007 Fundamentals 93 Schlumberger Project Creation 14. Click Finish. A window displays a summary of the setup information. To test the connection, click Test Data Source. 15. Click OK to close the message window. 94 OilField Manager 2007 Fundamentals Schlumberger Public The results of the test are displayed in a message window. Schlumberger Project Creation 16. Click OK you are returned to the Select Data Source window. Schlumberger Public 17. Select the Machine Data Source tabbed page. 18. Highlight the desired DSN and click OK. This step concludes the DSN setup. The Tables window displays. TIP: In this lesson we are only connecting to a small set of tables; therefore, we will accept the default settings. If you are linking to a rather large data source (i.e. Oracle database or SQL Server database), you would want to narrow the list of tables by filtering based on Qualifier and/or Owner. OilField Manager 2007 Fundamentals 95 Schlumberger Project Creation 19. Click OK to continue. The Select Source Tables window displays. 20. Select the appropriate tables to link to the OFM project (e.g., HeaderID, Monthlyprod). Once the tables are made available to OFM (in the list of Available Tables), the steps to associate those tables to the project are straightforward, as in the previous exercises. Complete the steps to create the project (linking to SQL Server). Review Questions • What methods can you use to create an OFM project? • Describe the hierarchy of an OFM database from highest to lowest. • What is the Linked Tables Method and why do you need to use it? Summary In this module, you: • Analyzed table types • Populated the project with ASCII data files • Lined the project with data from external ODBC sources In the next module, you will learn how to access core functionality in the OFM environment and how to use project panes. 96 OilField Manager 2007 Fundamentals Schlumberger Public Exercise 22 Linking to SQL Server Schlumberger Project Creation NOTES Schlumberger Public OilField Manager 2007 Fundamentals 97 Schlumberger Project Creation NOTES Schlumberger Public 98 OilField Manager 2007 Fundamentals Schlumberger Project Administration Module 3 Project Administration The Graphical User Interface (GUI) was completely redesigned in 2005.

This redesign of the GUI has enabled users to quickly access and leverage the core functionality and features within the OFM environment. Accessibility through much of the functionality OFM provides is achieved through the use of project panes. Learning Objectives In this module, you will successfully learn how to perform the following procedures within this workflow: Changing the layout • Working with panes • Edit completions, wellbores, patterns • Understanding units, multipliers, PVT data • Editing table schema • Editing categories Lesson 7 Schlumberger Public • Changing the Layout The Layout menu command enables you to organize the display with predefined layouts. Select View > Panes > Layout to access each of the predefined layouts. Opening Panes Panes can be opened from the View menu. Opened panes have a checkmark displayed to the left of them in the view menu indicating that the pane is opened. OilField Manager 2007 Fundamentals 99 Schlumberger Project Administration Hiding/Showing Panes Panes that are open but not displayed in the main OFM window are displayed as a tab on an open pane. The horizontal pin located in the upper-right corner of the pane indicates that the pane is not docked. Moving the mouse away from the pane, results in the pane being hidden. Docking Panes/Disabling Auto Hide To dock panes or disable the Auto Hide feature, click the horizontal pin in the upper-right corner of the pane you want to dock. This action docks the pane in the OFM main window. The image pictured below shows the results when you pin a pane to the main window. Schlumberger Public NOTE: Clicking the pin again turns the Auto Hide feature On. Floating/Docking Panes NOTE: To dock the pane, double-click in the header of the pane. The pane is restored to its original location. Select the pane you want to move, drag it to the desired location, and release the mouse. The image below shows the results of a floating pane. Positioning Panes Panes can be moved to any location within the OFM main window. To reposition a pane, select the pane and drag it to the desired location. An outline of the pane is displayed showing where the pane will be relocated. Panes can be repositioned within another pane, displayed as a tabbed page of another pane, or as a docked pane within the OFM main window. 100 OilField Manager 2007 Fundamentals Schlumberger Project Administration Detaching Tabs from Panes With the new OFM graphic user interface, you can detach tabs from panes that can float or sit in front of the OFM main window or dock along either side of the main window. Detached tabs can also be combined with other docked panes. 1. Select the tab and drag the pane to the desired location. NOTE: The detached tab is indicated by a dashed line. Schlumberger Public 2. Release the mouse. The pane docks in the new location. Editing the Database The OFM Database menu command is accessible from all analysis modes. It is important to note that all changes made will impact the database. Use these options with caution. OilField Manager 2007 Fundamentals 101 Project Administration Schlumberger Completion – displays the Delete/Rename dialog. This dialog enables you to remove or rename UNIQUEIDs (completion names) from the database. Wellbore – displays the Delete/Rename dialog. This dialog enables you to delete or rename Wellbores from the database. Schlumberger Public Patterns – patterns are groups of wells. The portion that each individual well contributes to the group varies with time and is calculated by applying a factor to the individual well data. Selecting the Patterns menu command displays the Edit Patterns dialog. This dialog contains a list of pattern data to select one or more patterns to display on the base map. 102 OilField Manager 2007 Fundamentals Schlumberger Project Administration Editing OFM Units The Edit OFM Units dialog enables you to add or edit units of measurement to your project. This is useful when converting currency or when defining units required by the project not included by default in the OFM database. 1. Select Database > Units. The Units dialog displays. Schlumberger Public 2. Click Add Unit. The Edit OFM Unit window displays. 3. Enter a value in the Metric, English, and Conversion fields, or modify the values currently displayed. 4. Click OK. OilField Manager 2007 Fundamentals 103 Schlumberger Project Administration Multipliers The Edit OFM Multipliers dialog enables you to create, edit, or delete unit multipliers for variables. The OFM multiplier functionality is useful for converting existing data, creating conversion factors, or defining multipliers that are not included in the OFM database. 1. Select Database > Multipliers. The Edit OFM Multipliers dialog displays. 3. Enter a value in the Field, Metric, Scientific, and Conversion fields, or modify the values currently displayed. 4. Click OK. PVT Data Edit PVT Data from the PVT Entity Name window. The PVT Entity Name window contains a Select One section, which lists entities such as wells, reservoirs, fields or surveys, for example. PVT data for the selected entity or item can be edited and stored in a database that is automatically accessed and used when calculations that require PVT data for the entity are performed. 104 OilField Manager 2007 Fundamentals Schlumberger Public 2. Click Add Multiplier. The Edit OFM Multiplier window displays. Schlumberger Project Administration The PVT Entity Name window also enables you to add an entity, delete an entity, or rename an entity in the Select One list. Predefined PVT table data for one entity can by copied to another (New) entity. Schlumberger Public Editing Project Structure There are two parts of an OFM project: the design (structure) and the data. This topic demonstrates how to edit a project in both the design and the data. A typical OFM project has many tables and each table has many fields/variables. OFM does enable users to interactively add/delete/rename tables, fields, as well as change the project settings/associations regarding its structure. Editing Schema Table The Edit Schema Tables dialog enables you to create tables in Access and locate and recognize those tables in OFM. Tables can be defined in either Access or OFM. Operations, such as editing, deleting, and adding tables and fields can be performed from the Edit Schema Tables dialog. At the project level, the dialog consists of the OFM Representation section and the Tables tabbed page. 1. Start OFM. 2. Open the Demo2007.OFM workspace. OilField Manager 2007 Fundamentals 105 Schlumberger Project Administration 3. Select Database > Schema Tables. The Edit Schema Tables dialog displays. NOTE: The level of the tree selected in the OFM Representation section of the dialog determines what information will be displayed on the right side of the Edit Schema Tables dialog. If the top level of the project is selected, only the Tables tabbed page is displayed. You must select a table to display the Table and Fields tabs for that table. 4. To add an OFM table, locate the OFM Representation section of the window, select the Demo2007 folder and rightclick. A shortcut menu displays. 5. Select Add. 106 OilField Manager 2007 Fundamentals Schlumberger Public To remove/detach an OFM table from its source (Access) table, clear the check box in front of the source table. For example, clearing the MONTHLYGASINJ check box detaches the table from the OFM project without deleting it from the Access database. Schlumberger Project Administration The Edit Schema Table dialog displays a NewItem table in the OFM Representation section of the window. 6. Replace the default table name NewItem with NewMonthly. OFM assumes that the table is of Monthly type and creates the default fields UniqueID and Date. Schlumberger Public 7. Select the Fields tab. The Fields tabbed page displays. OilField Manager 2007 Fundamentals 107 Schlumberger Project Administration 8. Enter NewOil in the Add New Field text box and click Add. The new variable/field NewOil is added into the table. 9. Repeat the previous step, this time adding NewGas and NewWater variables. NOTE: The newly added fields are displayed in the Available Fields section of the dialog. Once the fields are created, clearing the checkbox in front of the field detaches the field from the project; it does not delete it from the database. Next you will assign attributes to the NewOil field. 10. Select NewOil. The properties for this field are displayed on the right side of the Edit Schema window. Schlumberger Public 108 OilField Manager 2007 Fundamentals Schlumberger Project Administration 11. Locate the Variable section of the Field tabbed page. Select Single from the Type list field. 12.

OilField Manager 2007 Fundamentals 113 Schlumberger Project Administration Review Questions • How do panes help you control the display in OFM? • When you use the OFM Database menu commands, what is the impact on the OFM database? • Describe the structure of an OFM database. Summary In this module, you: Changed the default layout • Familiarized yourself with opening, hiding, floating, docking and positioning panes • Edited completions, wellbores, and patterns • Reviewed units, mulitipliers, and PVT data • Edited the schema table • Edited categories In the next module, you will learn how to customize the basemap. 114 OilField Manager 2007 Fundamentals Schlumberger Public • Schlumberger Project Administration NOTES Schlumberger Public OilField Manager 2007 Fundamentals 115 Schlumberger Project Administration NOTES Schlumberger Public 116 OilField Manager 2007 Fundamentals Schlumberger Basemap Customization Module 4 Basemap Customization The basemap is the first screen you see when opening a project. It is probably the last window you see before closing the project. Managing a distinguishable Basemap helps reduce confusion and mistakes. Prerequisites If you do not already have your OFM application open, please open it now. Then, load the Demo2007 project. You will be using this project for all exercises in this module. Learning Objectives In this module, you will successfully learn how to perform the following procedures within this workflow: Edit Map Association • Edit Map Display • Modify Map Properties • Zoom/Unzoom • Apply Map Annotations and Deviations • Creating/Editing Map Associations (interactively) Lesson 8 Schlumberger Public • Map Association Data The basemap will not display correctly until the map associations are set up. OFM provides suggestions but may not activate the desired associations. In this section, manipulation of the map associations is discussed. Exercise 23 Editing Map Association Data 1. Select Edit > Map >Association. OilField Manager 2007 Fundamentals 117 Schlumberger Basemap Customization The Map Association Data window displays. TIP: Coordinates and Depths information must be located in the master table. Well Type – Expression can be associated to any project variables (including input variables, calculated fields, and calculated variables which will be addressed more extensively in Reporting and Creating Calculated Variables. Well Type – Expression, upon association, will lead to the window in step 2. You will need to make the correct choice as in step 3. If you know that your X and Y-coordinates are in LatLong, click Coordinates located at the bottom left corner of the dialog. Then check the Convert my LatLong coordinates to UTM box, select the reference system, and click OK. OFM automatically does the job for you. Schlumberger Public Other map fields are likely text fields and can be mapped to any text fields in any static tables (same as Well Type – Table fields). Well Type - Table is the most common association for well display, color and attributes. You can associate/map this specification to any of the text fields in any of the static tables. 2. From the Well Type – Table select Sc.Lease from the list and click OK. 3. Select Create from data option because symbols for the Lease fields are not predefined in the WellType.def file (in the \\...\symbols directory). 118 OilField Manager 2007 Fundamentals Schlumberger Basemap Customization 4. Click OK. The remaining associations should be self-explanatory. If you know which fields in your database correspond to the OFM map fields, associate them. In this project, it is likely that OFM would suggest the correct fields so you do not have to make any changes. 5. When all map associations are complete, click OK. The basemap displays with the color and attribute-coded wells. Exercise 24 Moving the Legend (Optional) 1. To display the legend on the basemap, from the View menu, select the Legend command.

In reality, most users are only interested in a subset of their working projects. The concept of filtering in OFM has proven to be very useful for all users as good filter criteria can really optimize the time to perform analysis, guarantee correct results, and maximize productivity. The OFM Filter pane is pictured below. NOTE: One of the most frequently used Filter operations is Clear. To guarantee that your filter criteria are applied to the entire set of wells (entities), clear any previously applied filters (unless you want to perform nested filters). Schlumberger Public Learning Objectives In this module, you will successfully learn how to perform the following filtering procedures: • Filter by Completion • Filter by Table Data • Filter by Category • Filter by Match • Filter by Well List • Filter Using Map Area • Filter by (OFM) Query • Using Step Functionality • Project Filtering • Other Filtering Methods OilField Manager 2007 Fundamentals 145 Schlumberger Filtering Lesson 10 Filter by Completion The Filter by Completion option is used to create a subset of data by selecting one or more records from the filter option columns. Filter by Completions dialog box displays by default two columns in one screen, the first one is fixed and is the Completions column the second one is not fixed and user can select one of these categories: Alias, Fieldname, Lease, Logdata, Reservoir, Sandname, Uniqueid, or Welltype. Exercise 34 Filtering by Completion To filter the data by Completion: 1. Open the Demo2007 project. 2. From the Filter pane click , Filter By Completion. The Filter By Completion window displays. TIP: Clear removes any previous selections. Select All highlights all completions. Schlumberger Public In previous OFM releases, only the full Completion name could be displayed in the list for user defined selections. By default OFM now displays both the full completion and alias name in one screen. Additionally, you may change the view from Alias to another category for display in the second column by selection the Second Column Info drop-down list. The CTRL or Shift keys help the user to select multiple wells or entities of interest. Clicking the column headers automatically sorts the well entities. 146 OilField Manager 2007 Fundamentals Schlumberger Filtering 3. While holding the CTRL key on your keyboard, use the mouse to select the following completions: • Blue_1:He_0 • Blue_10:Ad_1A • Blue_11:Li_1C • Blue_14:Li_1C Schlumberger Public 4. Click OK the Filter by Completions dialog closes and the basemap displays. OilField Manager 2007 Fundamentals 147 Filtering Schlumberger 5. Select Edit > Map > Annotations. The Map Annotations dialog displays. 7. The basemap does not adjust to display the selected wells (zoom). You can ask OFM to automatically zoom in the selected wells by selecting Tools > Settings. The Settings window displays. 148 OilField Manager 2007 Fundamentals Schlumberger Public 6. A checkmark displays to the left of the option Display active map annotations. Select the checkbox to clear it and click OK. Schlumberger Filtering 8. Select the Maps tab. 9. Check Auto zoom map around selected wells. Click OK to close the Settings window. 10. From the Filter pane click , Group All Selected Items icon. The wells display in magenta indicating that they have been loaded into memory as one entity. Schlumberger Public OilField Manager 2007 Fundamentals 149 Schlumberger Filtering 11. Locate the Step toolbar at the top of the OFM main window. The basemap now only has one well highlighted in magenta, Blue_1. Lesson 11 Filter by Table Data To select well (entities) that have data in a certain table, use the Filter by Table Data option. For example, you may have a well type field built to your project, which consists of oil, gas, and water wells. You want to select the wells that have historical oil production. Selecting the oil wells from a category may not satisfy the criteria, as some wells that are tagged as oil wells may not 150 OilField Manager 2007 Fundamentals Schlumberger Public 12. Click the drop-down arrow and select the first well, Blue_1:He_0. Schlumberger Filtering have any production. Therefore, selecting the wells from the production table is a better solution. Exercise 35 Filtering by Table Data Now try to simulate this procedure. In this exercise filter by Table Data. 1. Clear the filter from the previous exercise. 2. Expand the Table Data node located in the Filter pane. Schlumberger Public . 3. Select MONTHLYPROD table from the list of tables. The basemap returns all wells with production data. OilField Manager 2007 Fundamentals NOTE: The output data at the top of the filter pane shows that 120 wells meet the filter criteria. In other words, 120 wells have data in the MONTHLYPROD table. 151 Schlumberger Filtering 4. Clear the filter. 5. Select wells that have test data by selecting the TEST table. A list of 21 wells that meet this filter criterion is returned. 6. Select MONTHLYPROD and TEST tables from the list. The filter is applied and only the completions that have records in both the MONTHLYPROD and TEST tables are displayed on the basemap, 20 wells meet the criteria. Schlumberger Public Question What do you think the results mean? Why 20 and not 21? Can you single out the difference (well name)? Lesson 12 Filter by Category The prerequisite for this operation is all categories used must be previously defined in the project. For example, take a look at the wells that belong to the BERRINGER lease (provided that LEASE is a category). 152 OilField Manager 2007 Fundamentals Schlumberger Filtering Exercise 36 Filtering by Category 1. Clear the filter. 2. Expand the Category node and select LEASE. . Schlumberger Public 3. Select BERRINGER. The basemap shows 94 wells that belong to the BERRINGER lease. 4. To select wells in either BERRINGER or TRAMMEL, select both checkboxes. The basemap shows 129 wells. Obviously, the TRAMMEL lease has 35 wells (129-94=35). 5. Clear the filter. 6. Expand the LEASE node and select BERRINGER from the list of available leases. OilField Manager 2007 Fundamentals 153 Schlumberger Filtering 7. Expand the RESERVOIR node and select all ADOBE reservoirs. Schlumberger Public . Question Select the oil wells that belong to the LITMUS reservoirs. How many wells are there? Lesson 13 Filter by Match OFM also provides a Filter by Match option. This enables you to search for the list of desired wells. The match can be performed by well name or alias name. 154 OilField Manager 2007 Fundamentals Schlumberger Filtering Exercise 37 Filtering by Match 1. From the Filter pane select Match and right-click. A shortcut menu displays. 2. Select Add. The Match dialog displays. Schlumberger Public 3. In the Completion Key Match field, type BL*. This option is not case sensitive. 4. Click OK. The Match dialog closes, and you return to the OFM main window. 5. Check Match 1 in the Filter pane. OilField Manager 2007 Fundamentals 155 Schlumberger Filtering The map displays forty wells that satisfy the filter criteria. 6. Select Match1 and right-click. A shortcut menu displays. Schlumberger Public 7. Select Edit from the shortcut menu. The Match window displays. 8. In the Completion Key Match field, type B* and click OK. 9. OFM allows you to input multiple search criteria. Select Match and right-click. A shortcut menu displays. 10. Select Add from the shortcut menu. The Match window displays. 11. In the Completion Key Match field, type R*. 156 OilField Manager 2007 Fundamentals Schlumberger Filtering 12. Check Match2. The basemap returns 68 wells. NOTE: If you have a list of search criteria (search characters), you may want to save that with the Save option and re-use that list with the Open option. Lesson 14 Filter by Query Schlumberger Public You have done several filter techniques that deal with entities (i.e., well name) and data at static level (i.e., sort category value). However, the most important data is production data, which changes over time. To filter to that dynamic level of data, use the Filter by Query option. For example, select the wells that have produced more than 500 bbls per month at least once in their production history. Exercise 38 Filtering by Query 1. From the Filter pane select OFM Query and right-click. A shortcut menu displays. OilField Manager 2007 Fundamentals 157 Schlumberger Filtering 2. Select Add. The OFM Query window displays. NOTE: If queries were not previously created, you have to create one by clicking Edit. Schlumberger Public TIP: Monthlyprod.Oil is an input variable. It is found from the Project Variables list. Click the Project Variables button and select the Monthlyprod.Oil variable from the list. Click Add (or double-click the variable to add it to the above window). All variables in the project can be found and added this way. The keypad can be used to add non-text characters, logical operators, and keywords used in a typical query statement (if you don’t want to use the keyboard). The Delete and Clear buttons provide quick editing capability. Keep in mind that in OFM, the AND operator is represented by the “&” (ampersand) character, the OR operator is represented by the “|” (vertical bar) character, and the NOT operator is denoted by the “!” (Exclamation mark). 3. Click Edit. The Create Query window displays. If you are familiar with query languages such as SQL, this interface mimics the WHERE portion of your query statement. 4. In the text window below, enter Monthlyprod.Oil > 500. All the text characters are not case-sensitive. 158 OilField Manager 2007 Fundamentals Schlumberger Filtering 5. Click OK to return to the OFM Query window. The filter query statement appears next to the Edit button. 6. Since you want to get the wells that produced more than 500 bbl a month at least one time, enter 1 at the time(s) box. Leaving it at 0 yields the same result, as 0 means default in OFM, and the default occurrence is 1. Click OK. 7. From the Filter pane select the checkbox to the left of the newly created query. The basemap appears with 99 wells. Schlumberger Public 8. Clear the filter and re-access the OFM Query window. 9. In the OFM Query dialog, enter Monthlyprod.Oil > 500 & Date >= 19900101. In the above statement, with the AND operation, the command told OFM to only apply the filter to monthly oil production records from January 1st, 1990, ignoring all records before that date. OilField Manager 2007 Fundamentals 159 Schlumberger Filtering 10. Click OK. You are returned to the OFM Query window. Enter 3 in the time(s) text field so that at least three instances of the criteria are met. Make sure the Consecutively box is not checked. 11. Click OK to save the query. The OFM Query window closes. 12. Select the checkbox to the left of the newly created query, OFM Query 2. Schlumberger Public Thirty-one wells return, meaning each of those 31 wells has produced at least 500 barrels of oil per month more than (or equal to) three times in its producing history since 1990. 13. Select OFM Query2 and right-click. 14. Select Edit. The Create Query window displays. 15. Nest in another condition to check for gas production (i.e., searching for the wells that have high oil and low gas production). Append this line to the end of the previous query statement: & Monthlyprod.Gas < 500000. 16. Run the query again. Only 18 wells return. 17. Select OFM Query2 and right-click. 18. Select Edit. The Create Query window displays. 160 OilField Manager 2007 Fundamentals Schlumberger Filtering 19. Add in the parentheses to the query statement. Enter (Monthlyprod.Oil > 500) & (Monthlyprod.Gas < 500000) & (Date > = 19900101). Schlumberger Public 20. Now rerun the query. It will return the same result. However, by adding parentheses, the query statement is more readable and manageable. The order of precedence is very important in any type of query language. Parentheses verify that the query is evaluated in the order that the user specifies and helps avoid unnecessary errors. It is recommended that you get into the habit of adding parentheses. 21. Use Filter by Query to find the wells that produce at least 5000 bbl of oil or 2000000 scf of gas for at least 3 consecutive times since 1990. Your query should return 19 wells. 22. Use Filter by Query to find the wells that produce at least 50 bbl of oil for at least 3 consecutive times since 1998. Save the query as Prod_Wells98. Your query should return 18 wells. 23. From the Filter pane, click the Save icon and select To Well List. 24. Save it to your desired directory as Prod_Wells98.txt. You may be using this list for future tasks (e.g., Forecasting). 25. Select the Filter Archive tab located at the base of the Filter pane. Select the Archive node, right-click and select Add. A new node is added. OilField Manager 2007 Fundamentals 161 Schlumberger Filtering 26. Rename the node Prod_Wells98. NOTE: OFM supports nested filtering (or stage filtering). That means you can apply your current filter on the previously filtered list. This operation cannot involve Clear Filter. NOTE: You can have all the arguments in a logically combined query statement, but the statement then could be very difficult to maintain, troubleshoot, and understand (not taking into account the limitation of the query statement buffer size). 27. To filter the wells producing more than 2000 bbl of oil, have test information, and belong to the BERRINGER lease. Expand the Category node, then the LEASE node, and check BERRINGER. 28. Expand the Table Data node and select TEST table. 29. Select OFM Query and right click. Select Add from the shortcut menu. The OFM Query window displays. 30. Click Edit. The Create Query window displays. 31. Type Monthlyprod.Oil > 2000. 33. Select the checkbox to the right of the filter. The result of your nested filter is displayed. Do not clear the filter. Additional Filtering Options There are many more features related to Filtering. They are listed in the table below. Icon None 162 Action Invert Filter Description Inverts the selection and selects the wells that do not meet the filter criteria. Filter by DCA Data Applies for the wells that have forecast data. Flagged Items When you are plotting information for the wells and would like to save some of them into a list to come back and perform further analysis you can flag (mark) them. Then after you close the plot window, you can ask OFM to retrieve such a list of wells by using this feature. Save Well List Saves filter to Well List. Save Scatter Set Saves filter to Scatter Set. Save Archive Saves filter to Archive. OilField Manager 2007 Fundamentals Schlumberger Public 32. Click OK to save the filter the query. Schlumberger Filtering Lesson 15 Invert Filter The Invert Filter command enables you to exclude the returned results of the filter criteria by inverting the selection and selecting the wells that do not meet the filter criteria. Exercise 39 Using the Invert Filter 1. Apply the desired filter. The filter is applied to the wells displayed on the basemap. 2. Click the Invert Filter icon. The reverse action is applied to the basemap. Lesson 16 Filter by DCA Data The DCA Data filtering option enables you to select decline curve analysis cases by phase or ration parameters. Exercise 40 Filtering by DCA Data Schlumberger Public 1. Expand the DCA Data node in the Filter pane. 2. Select one or more decline curve analysis cases. 3. Expand the Cases folder and select phase or ratio parameters to include in the filtered cases. Exercise 41 Flagging Items 1. Use the Step toolbar to view the well completions by clicking the First, Previous, Next, or Last icons. OilField Manager 2007 Fundamentals NOTE: There is no flag icon on the Filter pane. It is a menu selection item and only available when a plot is open by selecting Tools > Flag Item. 163 Schlumberger Filtering 2. Click the Flag icon, . A flag is displayed near the flagged well on the basemap. 3. Continue to flag any other wells of interest. 4. From the Filter pane, click Filter by Completion, . The Filter by Completion dialog displays. Notice that the Select Flag button is enabled. Schlumberger Public 5. Click Select Flag to select the components that have been flagged. 6. Click OK. The Filter By Completion dialog closes and only the flagged completions display on the basemap. 164 OilField Manager 2007 Fundamentals Schlumberger Filtering Exercise 42 Saving Filters The filter can be saved in three forms – well list, scatter set, and archive. Well List Well list stores the information of all the wells that meet the filter criteria in the text file format in the form of Unique IDs. 1. From the Filter pane, click the Save to Well List icon. The Well List dialog displays. 2. Enter the desired name in the File Name field and click Save. 3. To apply the filter from a previously created well list file, select the Well List node, right-click, and select Add. Schlumberger Public 4. Select the name of the previously saved *.txt file. Scatter Set Scatter Set contains the well Unique IDs either by category or filter name. Categories can be field name, lease, log data, reservoir, or well type. 1. From the Filter pane, click the Save to Scatter Set icon. The Save As Scatter Set File window displays. 2. Enter the desired name in the Current Filter As list field. 3. Select the Category radio button and select the desired category type. OilField Manager 2007 Fundamentals 165 Schlumberger Filtering 4. Click OK. The Scatter Set window displays. Filter Archive 1. After applying the filter, click the drop-down arrow to the right of the save icon and select To Archive. The Add Filter Archive dialog displays. 2. Enter a name in the Filter Archive Name list field and click OK. 166 OilField Manager 2007 Fundamentals Schlumberger Public In query, you can save the query setup and/or the query result. In other filter techniques, you can save the result, as the setup is not that important. However, if your filter procedure involves many steps (i.e., nested filter), it would be useful to save the procedure (steps) itself. Filter Archive helps you achieve that goal. Schlumberger Filtering 3. Select the Archive tabbed page on the Filter pane. The archive is displayed below the Archives node. NOTE: To apply the archived filter criteria, double-click on the archive or right-click on the archive and select Load from the shortcut menu. Schlumberger Public OilField Manager 2007 Fundamentals 167 Schlumberger Filtering Step Another feature that relates to filtering in OFM is Step (a global menu). You can set up OFM entity level from the Step pane. OFM will pre-process data and return information at the set Step level at retrieval time. For example, if you set Step to RESERVOIR, you are dealing with individual reservoir instead of well/completion level. From the drop-down well list, reservoir names will be displayed instead of well names. Clicking on the next or previous button will take you to the next/previous reservoir in the list. Schlumberger Public First Previous Next Last 168 Redirects you to the very first entity in the list Redirects you to the previous entity in the list (at level set in Step > Category). Redirects you to the next entity. Redirects you to the very last entity in the list. OilField Manager 2007 Fundamentals Schlumberger Filtering Lesson 17 Project Filter OFM has “smart-loading” algorithms to speed up project opening. The time it takes to open a project depends on how big your project is. It will take longer to open a 100,000-well project than a 100-well project. Still there are times that you would like for it to open faster. The problem may be even worse if you are working on a network project, and the network is somewhat slow. OFM provides the option of pre-filtering the wells. Applying this type of filtering (called Project Filter) to your project will cause it to read only the applicable list of wells, saving load time from reading the excluded wells. We are going to use the Demo2007 project database to demonstrate this functionality. Exercise 43 Using the Project Filter In this exercise we will limit the project to wells that belong to a specific rectangular region (bounded by x- and y-coordinates). 1. Open the Demo2007 project. Schlumberger Public 2. Locate the Project Filters node located in the Filter pane. 3. Select the Project Filters node and right-click. A shortcut menu displays. OilField Manager 2007 Fundamentals 169 Schlumberger Filtering 4. Select Add from the shortcut menu. The Edit Project Filter window displays. 6. Click OK. The Edit Project Filter dialog closes. 170 OilField Manager 2007 Fundamentals Schlumberger Public 5.

Schlumberger Public 174 OilField Manager 2007 Fundamentals Schlumberger Filtering NOTES Schlumberger Public OilField Manager 2007 Fundamentals 175 Schlumberger Filtering NOTES Schlumberger Public 176 OilField Manager 2007 Fundamentals Schlumberger Module 6 Project Variables Project Variables There are many different ways to classify OFM variables (also called project variables), depending on how you would want to use them. Based on the table types that the variables belong to (or created from), you would have monthly, daily, sporadic variables, etc… Based on data type, you would have date, numeric or alphanumeric (text) variables. However, the most recognizable classification, the OFM primary classification, is based on database (storage/processing) properties. Learning Objectives This module covers how to create calculated variables and calculated fields. You will have a chance to apply them in the next section, Reporting. At the completion of this module you will be able to: Edit Calculated Variables • Add Calculated Fields • Create Calculated Variables • Use Calculated Field Schlumberger Public • Lesson 18 Types of Variables There are three types of variables: • Input Variable • Calculated Variable • Calculated Field Input Variable is the simplest form of variable. Input variables are fields that belong to physical tables with physically loaded data. In other words, if you open the table in Access or in OFM you would see editable data. Input variables do not change value, i.e., every time a request is made to an input variable (on a specific entity), you would get the same copy of the data. In its Access database (project), OFM stores both the design and the data of the input variable. Calculated Variables are derived variables or dependent variables. OFM only saves the definition of a calculated variable, not its physical data. Therefore the value of a calculated variable may change from time to time. For example, each time a retrieval request for a calculated variable is made you may get a different copy of the data. The advantage of this variable type is that you always get the most up-to-date copy of the data, and you do not have to worry about project storage capacity. OilField Manager 2007 Fundamentals 177 Schlumberger Project Variables Calculated Field (formerly known as Imputed Variable) is a unique variable type in OFM. There are scenarios when neither input nor calculated variable would be sufficient to address. Fortunately, with the existence of Calculated Fields, those problems are resolved; and the combination of these three types of variables has been proven to be a complete solution for any practical purpose. The exercise arises with the grouping option. One perfect example to demonstrate the concept of calculated field is the Gas-Oil Ratio, defined as Gas/Oil. On an individual level (single well), it does not make any difference. Yet on grouped level, there is a big difference between ratio of the sums and sum of the ratios. As you group the wells, OFM groups (sums) Gas from the source, groups Oil from the source, and then takes the ratio. This is similar to taking the average (per well). What if you want to group individual (well) ratios? Lesson 19 Calculated Variables The first lesson involves divide by zero operation. In the Oil Industry many variables are defined as ratios, and people are dealing with zero denominators all the time. OFM imposes the following rule on all the arithmetic operations, “Any arithmetic operation with a null operand results in a null.” If you choose to handle this problem from a calculated variable perspective, you may get into trouble grouping (adding or averaging) or performing consequent arithmetic operations on that calculated variable. OFM offers a better way of doing it, with an intrinsic if statement to replace the unusable results by nulls. 178 OilField Manager 2007 Fundamentals Schlumberger Public The last exercise is even more complicated. Primary OFM data frequency is monthly, and users are used to creating (average) daily rates by dividing monthly productions by the reported numbers of producing days in the month. Grouping productions and producing days at the source and then taking the ratio would yield the (per well) average daily rate. Taking the ratios and then grouping them would result in a field daily rate. Depending on what you want to do with your data, you have to choose the correct implementation of which variable type to use. Schlumberger Project Variables Exercise 44 Editing Calculated Variables 1. Select Database > Schema Tables. The Edit Schema Tables window displays. 3. Schlumberger Public 2.

The Edit Schema Tables dialog closes and you are returned to the main OFM window. Exercise 45 Adding Calculated Fields Add the following calculated fields to your project, from the Monthlyprod table: 1. Name: PDOIL, definition: IIF( DAYS <> 0, OIL/DAYS, NULL ). Assign the attributes. Group option will be “sum” 2. Name: WCUT, definition: IIF( (WATER+OIL) <> 0, WATER/(WATER+OIL), NULL ). Assign the attributes. 3. Name: ON, definition: IIF( [OIL] OR [GAS] OR [WATER], 1, 0 ). Assign the attributes. (This variable may have been included in the project). Question What do you think the variables mean? Lesson 20 Calculated Variables There are virtually no limitations on how many calculated variables you can have in your project. Calculated variables can be exported/imported to/from similar projects (i.e., using a template). With more than 230 system functions in OFM, the calculated variable is one of the strongest functionalities that OFM users should take advantage of. In the scope of this course, we will be OilField Manager 2007 Fundamentals 183 Schlumberger Project Variables learning how to create a few of the most commonly used calculated variables. Most of them will be verified on the Report, your next module. The Demo2007.OFM workspace comes with a built-in set of typical calculated variables. Examine their definitions and attributes and use them as a starting point. Exercise 46 Adding Ratio Variable In this exercise you will add a ratio variable. 1. Open the Demo2007 project. NOTE: The Database > Calculated Variables menu command is a global menu command that you can access from any module in the project. 2. Select Database > Calculated Variables. The Edit Calculated Variables window displays. Schlumberger Public An individual or asset team may be familiar with a standard set of calculated variables. The User column classifies variables as: • Standard Company Calculated Variables • Calculated Variables for a specific asset team • An engineer’s personal set of Calculated Variables • A combination of the above points The Class column specifies the category type of calculated variables as: • Class monthly calculated variables only • Class daily calculated variables only • Class water flood variables only The window displays the subset of calculated variables of interest in an OFM project based on the User and Class selected. The default is to display all calculated variables. 184 OilField Manager 2007 Fundamentals Schlumberger Project Variables 3. Click Add Variable. The Edit Calculated Variable window displays. In the text field at the top of the dialog type Monthlyprod.Gas/Monthlyprod.Oil. 4. Click OK. The Edit Calculated Variable window closes, and the variable displays in the Equation section of the Calculated Variables window. 6. Assign attributes to the calculated variable. Select the Units tab and assign M as the Output Multiplier. In the Units section select cf/bbl. NOTE: It is recommended to assign more attributes for this variable (Report Headers, Plot Name, etc.). 7. Click Close. Exercise 47 Using Cumulative Variable Cumulative productions are always figures of interest. To create cumulative productions, OFM provides a system function named @CumInput(). This function calculates the running sum of the variable inside the parentheses (called argument), including prior cumulatives (precums). Ask your instructor for the concept and usage of precums in OFM. 1. Open the Demo2007 project. 2. Select Database > Calculated Variables. The Edit Calculated Variables window displays. 3. Select Add Variable. The Edit Calculated Variable window displays. OilField Manager 2007 Fundamentals 185 Schlumberger Public 5. In the Name field type CV.GOR. Leave User and Class fields unspecified. Schlumberger Project Variables 4. In the text field at the top of the dialog, type @CumInput( MonthlyProd.Oil ). 6. In the Name field type CV.CumOil. 7. Leave User and Class empty for this exercise. 8. Select the Units tab. 9. Select M for Output Multiplier and select bbl (bbl = = >m3) for Units. 10. Select the Report tab. In the Decimals field type 3. 11. Change the Heading to Cumulative and Oil. On the first row type Cumulative and on the second row type Oil. 12. Select the Plot tab. In the Curve Name field type Cumulative Oil. 13. Select the Plot tab and assign the following attributes: • Line Color – Green • Line Type – Solid • Line Width – 4 14. Click Close. The CumOil has been added to the project and can be found from the variable list. The @CumInput() function can only take input variable as argument. If your argument is not an input variable, use @Rsum() or @CRSum(). These system functions do not take previous volumes (precums) into account. 186 OilField Manager 2007 Fundamentals Schlumberger Public 5. Click OK. The Edit Calculated Variable window closes, and you are returned to the Calculated Variables window. Schlumberger Project Variables Exercise 48 Creating Calculated Variables Create similar calculated variables for Gas Cumulative and Water Cumulative. Exercise 49 Creating Date/Event Variables Many dates are very important to the project. Date of first production, date of last production, date of a specific event, etc., mark critical instances for analytical work. Even though dates and numbers resemble each other in many aspects, they are different. Therefore, dates are treated special when it comes to their use. 1. Select Database > Calculated Variables. The Edit Calculated Variables window displays. 2. Click Add Variable. 3. In the text field at the top of the dialog type @First( Date, (Monthlyprod.Oil > 0) | (Monthlyprod.Gas > 0) | (Monthlyprod.Water > 0) ). 4. Click OK. The Edit Calculated Variables window closes, and you are returned to the Calculated Variables window. 5. From the Define tab, enter CV.FirstProdDate in the Name field. 6. Select the Units tab. Locate the Units list field and select Date. 7. Select the Report tab. In the Heading section on the first row type First, on the second row type Production, and on the third row type Date. OilField Manager 2007 Fundamentals 187 Schlumberger Public NOTE: @First() and @Cfirst() functions do almost the same thing. @First() doesn’t require the second argument (the condition), whereas @Cfirst() imposes the existence of the condition. Schlumberger Project Variables 8. Do not change anything on the Plot tab. Click Close. Exercise 50 Creating a Calculated Variable Create a calculated variable for Date of Last Production using the @Last() or @CLast() function. When reporting (or plotting), date variables are displayed in number-like forms, i.e., 19900101.000. Even if you choose not to display the decimals, the date displays still resemble numbers. OFM provides a function called @FmtDate() so you can format the date variables to the displayed forms that you want, i.e., 1990/01/01 or Jan-01-1990. This function is used extensively on the report and headers (since headers can only be text). The output (return) of this function is a text string. 1. Select Database > Calculated Variables. The Calculated Variables window displays. 2. Click Add Variables. The Edit Calculated Variables window displays. 3. In the text field at the top of the dialog type @FmtDate( CV.FirstProdDate, “Mmm-dd-yyyy”). 5. In the Name list field type CV.DateofFirstProd. 6. Click Close. The variable has been added to the project. Exercise 51 (Dynamic) Computing Variables Sometimes, scrolling through all the records of a well (an entity) to find a specific record (i.e., maximum production) is time consuming, especially when the maximum production value varies from well to well and happens at different times. Even though OFM provides the sorting algorithm to make the task easier, having the dates shuffling up may not be a desirable by-product. Fortunately, OFM has system functions that can resolve such a concern. In this exercise, you are going to learn how to create a calculated variable that returns the maximum oil production rate for each well. You can even report the date where that peak production was achieved. 1. From the Calculated Variables window, click Add Variables. The Edit Calculated Variables window displays. 2. In the text field at the top of the window type @Tmax( Monthlyprod.Oil, Monthlyprod.Oil > 0 ). 3. Click OK. The Edit Calculated Variables window closes, and you are returned to the Calculated Variables window. 4. With the Define tab selected, in the Name field type CV.MaxOil. 5. Select the Units tab. Select bbl from the Units list field. 188 OilField Manager 2007 Fundamentals Schlumberger Public 4. Click OK. The Edit Calculated Variables window closes, and you are returned to the Calculated Variables window. Schlumberger Project Variables 6. Select the Report tab. In the Heading section on the first row type Max, on the second row type Oil, and on the third row type Production. 7. Select the Plot tab. Enter Maximum Oil Production in the Curve Name text field. 8. Select the following curve attributes: • Line Color – Dark Red • Line Type – None • Point Type – Filled Star • Point Size – 5 9. Click Close. Exercise 52 Creating a Variable Create a variable that reports the date where the well achieved its peak oil production. Exercise 53 Plotting Variables Versus Date Schlumberger Public Plot the MonthlyProd.Oil and CV.MaxOil versus Date and traverse through the wells/entities to see how the CV.MaxOil variable works. Question How could you plot only one value, right where the peak oil happens? Exercise 54 Creating Text Display Variables There will be times that you may want to display values on the report, plot and/or other modules as headers/footers. Numeric variables can certainly be displayed in their original format, yet they would not appear very neat. You may want to create calculated variables to convert the outputs to texts and display them better with attributes like names, units, multipliers, etc. In this exercise, you will look at several built-in variables (provided with the Demo2007 project) and create a couple of calculated variables. 1. Select Database > Calculated Variables. The Edit Calculated Variables window displays. OilField Manager 2007 Fundamentals 189 Project Variables Schlumberger 2. Select ghCumoil from the list of variables. The properties associated with the selected variable are displayed in the Calculated Variables window. From this window you can edit/modify this equation @FmtName(Oil.Cum, @Last(Oil.Cum)). Analogous to the syntax of the @FmtDate() function in your earlier exercise, this variable will return the value of the last cumulative oil production (based on monthly records), with the plot name and other numeric attributes assigned for its properties. 190 OilField Manager 2007 Fundamentals Schlumberger Public 3. Click the Edit button located in the Equation section of the window. The Edit Calculated Variable window opens displaying the definition of this variable. Schlumberger Project Variables 4. Click OK (or Cancel) to close the Edit Calculated Variable window. You are returned to the Calculated Variables window. Since this variable is used for retrieving the last value of Oil.Cum, it will use the variable attributes of Oil.Cum for display. Do not worry about assigning attributes for it (not even the field Width). 5. Select gh.Lease from the list of variables. Look at its definition. This variable retrieves the name of the lease the selected entity is related to. Schlumberger Public 6. Click Add Variable. The Edit Calculated Variable window displays. 7.

The Edit Calculated Variable window closes, and you are returned to the Calculated Variables window. NOTE: Spaces and parentheses are not required. The use of spaces and parentheses promotes readability and makes it easy to understand the structure of the variable. OFM calculated variables are not case-sensitive. 9. In the Name field type gh.lastGOR and leave the rest of the settings at their default value. 10. Locate and select the Ratio.GOR variable from the list. 192 OilField Manager 2007 Fundamentals Schlumberger Public Remember that this variable will only be used for displaying on the header, so it is using the attributes of the Ratio.GOR variable. It is a good time to look at what attributes were assigned to the Ratio.GOR variable. Schlumberger Project Variables 11. Select the Units tab and look at the units specifications. It should be set to cf/bbl (though it appears as cf/bbl = => scm/m3), since this project is set to the English unit system. NOTE: OFM reads the list of available units seen in Edit > Project > Units, to which you can add your own customized units. NOTE: If the plot name for Ratio.GOR is used then it will not be known that it is meant to be the last GOR. 13. (Optional) Select the Units tab and verify that the Output Multiplier is set to M. 14. Click Close. OilField Manager 2007 Fundamentals 193 Schlumberger Public 12. Select the Report and Plot tabs.

Learning Objectives OFM supports up to six graphs in one plot window. Each graph can have up to 6 vertical (Y) axes, but it can only have one horizontal (X) axis, also each y-axis can have multiple variables. In this module, you will successfully learn how to perform the following procedures: Create a graph with one y-axis • Create a graph with two y-axes • Create a plot with multiple graphs • Use Plot Lock and Graph Blow Up options • Create stacked graph/plot on entities • Create stacked graph/plot on variables • Use Sum/Average/% Contribution plot types • Create plot overlay • Use Plot Annotations • Use plot-related tools/utilities Schlumberger Public • Lesson 22 Basics of Plotting The following rules must be adhered to regarding plotting; • All project variables (again, project variables consist of input variables, calculated variables and calculated fields) may be plotted. • Text variables cannot be plotted. • Plot and Graph often are used interchangeably in many cases (especially when there is one graph in the window), but they may not be identical. Graph is the visual representation of the data. Plot is the housing of the graph(s). A plot (as in plot window) can contain single or multiple graphs.

In the next module you will learn about creating and formatting reports in OFM. Schlumberger Public OilField Manager 2007 Fundamentals 241 Schlumberger Plotting NOTES Schlumberger Public 242 OilField Manager 2007 Fundamentals Schlumberger Module 8 Reporting Reporting OFM, as an analytical tool, has its own features tailored for specific needs. It has the advantage of having more than 230 system functions and an environment for writing macro-like functions. An OFM report has been proven to be a powerful and effective tool for outputting information, processing/manipulating data, and testing customized variables. Unlike plotting, the fields displayed on the report do not have to be pre-constructed variables. Prerequisites Before going directly into the report module, it would be useful for you to get a basic understanding of different types of OFM variables. Learning Objectives • Create a Monthly Report • Create a Daily Report • Create a Sporadic Report • Formatting a Report • Additional Report Tools • Exporting to Microsoft Excel Schlumberger Public In this module, you will successfully learn how to perform the following procedures: Lesson 30 OFM Reports The OFM Report module is primarily used for retrieving datedependent data. Depth-dependent data (such as Log information) are output to the Log Report module. The Report module provides an interface for SQL-like statements and a result window. You can design and customize the output to present their data. A user–friendly editor includes many useful tools a practical reporting application should have. Rules • Do not mix sporadic variables with either monthly or daily variables on the report. • Static data can be retrieved at any time because they are unchanged with time. OilField Manager 2007 Fundamentals 243 Schlumberger Reporting • Monthly and Daily data are date-based, and there are algorithms to allow them to work compatibly (though not recommended). • Sporadic data, on the other hand, are different. When processing data requests, OFM 2007 treats sporadic data the same way it does monthly or daily data. In OFM 2007 sporadic data also can be grouped, unlike in previous versions. • Any arithmetic calculation involving a null operand results in a null. • A null data point is an empty data point. An empty cell in Excel constitutes a null (an empty field) in Access. Sometimes, a null is equivalent to a zero (0). Other times, it constitutes a missing data point. • In-line calculations are allowed on the report. Thus, resulting null values could easily happen. In such a situation, you may need to have some null-handling procedures before carrying out the calculations in order to not see the nulls. • On the report, a numeric null is displayed as an asterisk (*). All OFM variables can be reported. The variables can be accessed from the Project Variables list in the Edit Report dialog window. In this lesson, you will learn to create simple reports to output monthly (with static), daily (with static), and sporadic data. Exercise 68 Creating a Monthly Report In this exercise you will create a monthly report. 1. Clear any previously applied filter. 2. Group all the wells together by clicking the Group icon. 3. Select Analysis > Report or click the Report icon located in the Analysis toolbar. A blank report displays. 244 OilField Manager 2007 Fundamentals Schlumberger Public Lesson 31 Report Variables Schlumberger Reporting 4. In the Select text box, enter @name(), date, monthlyprod.oil, monthlyprod.gas, monthlyprod.water. Schlumberger Public @name() is a system function. You can click the System Functions button and select Name from the list. The @ sign and the parentheses are automatically added to denote this is an OFM system function. Date, monthlyprod.oil, monthlyprod.gas, and monthlyprod.water are all input variables. You can type them in (with the commas), or select the variables from the list to add in (again, double-click or highlight-and-Add). To access variables, you have to be on the Project Variables level. Since you are currently on the System Functions level (to get @name()),click the Project Variables button. After you add a new variable into the Select variable list (without typing), OFM adds a comma after the last variable to separate it with the newly added variable. The Keypad contains Command/Keyword buttons, logical operators, and numeric keys. If needed, you can add them to the Select box (without selecting the Add button). OilField Manager 2007 Fundamentals 245 Reporting Schlumberger 5. Click OK. OFM generates the report and displays it in the OFM main window. The first variable (@Name()) is a static variable, as it is a constant with respect to time. The other variables are in monthly frequency. 6. Click Next in the Step toolbar to go through a couple of wells to see how the data is refreshed. Sometimes you will get to a well that does not have monthly data. When this occurs an empty report displays. 8. Double-click on the report and add sc.reservoir, monthlyprod.gor, and ratio.gor to the Select text field. 246 OilField Manager 2007 Fundamentals Schlumberger Public 7. Select Blue_1:Li_1C. Add a real static variable and a few of those calculated fields and calculated variables that were created earlier. Schlumberger Reporting 9. Click OK. The requested report displays. Notice that the values of monthlyprod.gor and ratio.gor are the same (single well level). 10. Group all the wells, and then you can see that they are different. Exercise 69 Reporting Calculated Variables Report the CV.CumOil, CV.FirstProdDate, CV.MaxOil calculated variables and Monthlyprod.On calculated field to verify their correctness. Lesson 32 Daily Report Schlumberger Public Only a subset of the wells in this project has daily data. To avoid seeing empty reports, filter the well list down to those that contain daily data (from the Dailyprod table). Exercise 70 Creating a Daily Report 1. Clear any previously applied filters. 2. Group all the wells. 3. Click the Report icon. The Edit Report window displays. OilField Manager 2007 Fundamentals 247 Schlumberger Reporting 4. In the Select field type @name(), date, dailyprod.oil, dailyprod.gas, dailyprod.water. Question Why do you have a lot of nulls at the beginning of the report? It has something to do with daily precums. For detailed information about precums ask your instructor. Exercise 71 Using a Daily Frequency Calculated Variable For report sc.lease, create a daily frequency calculated variable (i.e., CV.DLYGOR) and retrieve the result on the report. 248 OilField Manager 2007 Fundamentals Schlumberger Public 5. Click OK. The report may return several null values. Scroll through the report to see the data. Schlumberger Reporting Lesson 33 Sporadic Report In OFM 2007 sporadic data can be grouped. We want to filter the well list to those that have sporadic data. In this project, TEST is a sporadic table. Before you begin, clear any previously applied filter. Exercise 72 Creating a Sporadic Report 1. From the Filter pane expand Table Data and select TEST. Schlumberger Public 2. Select well ORANGE_1:Ad_4 from the Step toolbar. The selected well is highlighted on the basemap. 3. Click the Report icon to generate a report. The Edit Report window displays. OilField Manager 2007 Fundamentals 249 Schlumberger Reporting 4. In the Select field type @name(), date, test.oil, test.gas, test.water. Schlumberger Public 5. Click OK to display the report. 6. Review the report. Note that the data points are reported but with no specified dates. Double-click on the report. The Edit Report window displays. 250 OilField Manager 2007 Fundamentals Schlumberger Reporting 7. Replace the Date variable with Test.Date and click OK. You can see that the data are now reported correctly for this well. Static data also can be displayed with sporadic data. 8. Double-click on the report and the Edit Report dialog displays. Add sc.lease to the parameter list and click OK. Schlumberger Public Lesson 34 Format a Report In addition to creating a sensible report, making it readable is also important. OFM provides a reasonable set of features that enable you to narrow down the date range, apply sort criteria, display subtotals, as well as enhance the quality of the report output. OilField Manager 2007 Fundamentals 251 Schlumberger Reporting Exercise 73 Formatting a Report 1. Clear any previously applied filter. 2.

All report attributes seen are specified to the selected variable. • Width is the numeric value of the display field. You may see a string of asterisks (******) on the report if the width of the column is not wide enough to display the value. If a text field is not wide enough, the text is truncated. • Decimal Places are number of decimal places to be displayed when the variable returns a numeric value. • Justification aligns text in the columns to the left, center or right. By default, a text field is left justified and a numeric field is right justified. • Display enables you to set the unit system to either Metric or English. Modifying this value overwrites the project system unit. • Heading First Row contains the variables for the first row header. • Heading Second Row contains the variables for the second row header. OilField Manager 2007 Fundamentals Schlumberger • Heading Third Row contains the variables for the third row header. • Hide Duplicates hides duplicate data contained in the selected column if it is identical to the previous value. • Units are display unit in the column header. Any specification here overwrites the specification set with the variable. The values displayed are in accordance to this unit. • Multiplier displays a list of multipliers that uses a multiple of the database unit. Modifying this value overwrites the preset multiplier of the selected variable. The values displayed are in accordance with this multiplier specification. Reporting 8. Select Edit > Header/Footer. The Header/Footer window displays. Schlumberger Public 9. Type @Today(), “Last“+gh.cumoil, “Last“+gh.cumgas, “Last“gh.cumwater and align all headings to the left. NOTE: You can edit, delete, or add more headers. You can also save all the headers to apply them to additional reports. Footers function in the same manner as headers, the only difference is the location of the data displayed.

Review Questions 270 • Why should you filter a well list before creating a daily report? • What is the structure of a report and how are the different parts saved? OilField Manager 2007 Fundamentals Schlumberger • Why would you want to create a table from a report? • To what formats can you export an OFM report? Reporting Summary In this module, you: • Created a monthly report • Created a daily report • Created a sporadic report • Formatted a report • Utilized additional reporting tools • Exported the report data to Microsoft Excel In the next module you will learn about export data project data. Schlumberger Public OilField Manager 2007 Fundamentals 271 Schlumberger Reporting NOTES Schlumberger Public 272 OilField Manager 2007 Fundamentals Schlumberger Module 9 Exporting Exporting Imagine that you are working on a shared (network) project, which has thousands of wells. You are interested in just a hundred wells that belong to a certain field and you have to go on a business trip for a while. Knowing that you will not have the network connection, you may have to do something beforehand so you can still work on your project while out of the office. OFM provides some useful options that can be used to copy all the data or a subset of the data for the filtered list of wells to your local hard drive. You can export all the critical information to text files so you can rebuild your complete database if something goes wrong. For maintenance purposes, you might want to keep a copy of all the text files (definition data). All the exporting options (related to the project) can be accessed from the global Database menu. Learning Objectives • Exporting Database Tables • Exporting Variables to Tables • Exporting Text Load Files Schlumberger Public In this module, you will successfully learn how to perform the following procedures: Lesson 36 Export Database Tables In this lesson you will export database tables.

Scheduling (Eclipse) Exports The Schedule (Eclipse) export exports text files in the format that the Schedule (Eclipse suite) can read and thus get information to Eclipse. Associate the OFM variables/parameters with the expected Schedule (Eclipse) variables and specify the names and directory. OFM displays the Schedule Export Option 278 OilField Manager 2007 Fundamentals Schlumberger Exporting dialog for you to enter the specifications. You will have the option to export these files using the well aliases having the coordinates in Metric units. Schlumberger Public Exporting DCA Data The Export DCA Data enables you to export saved forecast data, results of all cases, and all the phases. The window is accessed by selecting Database > Export> elected Text Load File(s) > DCA data. The window is composed of three tabbed pages – Case and Phases, Results, and Forecast. The tabbed pages of the Export DCA Data window are described below. OilField Manager 2007 Fundamentals 279 Schlumberger Exporting • Cases and Phases enables you to select a case (or all cases) and the phase(s) to be exported. • Results tabbed page enables you to specify the file name and select the variable of interest to export. • Forecast tabbed page enables you to specify the file name and date range to export forecast data (date frequency). Review Questions • Why do you need to use caution when exporting variables to tables? • Why would you export text load files from OFM? • What data types can you export from OFM? Summary In this module, you: Exported database tables • Exported variables to tables • Exported text load files In the next module you will learn about OFM utilities for project management, data processing/manipulation, and customization. 280 OilField Manager 2007 Fundamentals Schlumberger Public • Schlumberger Exporting NOTES Schlumberger Public OilField Manager 2007 Fundamentals 281 Schlumberger Exporting NOTES Schlumberger Public 282 OilField Manager 2007 Fundamentals Schlumberger Module 10 OFM Tools and Settings OFM Tools and Settings OFM has a uniquely intuitive collection of tools (utilities) that provide users with quick access to project management, data processing/manipulation, and customization functionality. This section describes these tools and their use. By the end of this module you should be able to understand and utilize these features to customize your projects, to make them more useful, more accessible, and to extract the best values from your data. Learning Objectives In this module, you will successfully learn how to perform the following procedures: • Manage Project Settings • Use Data Normalization • Use the Data Register Schlumberger Public Lesson 39 Project Settings Project settings are managed from the Settings dialog. To access the dialog select Tools > Settings. Preferences The Preferences tabbed page enables you create user defined settings for displaying variables, warning and prompts, and registry settings. • Input Variable Lists – Your database many have tables/fields that are defined but do not contain any data. OFM provides the option to display only the variables (fields) that are OilField Manager 2007 Fundamentals 283 Schlumberger OFM Tools and Settings associated with some data to refine the long list of input variables to be displayed. This is just a display option. Your empty variables will not be deleted from the database. The default setting is to “display all variable name in lists”. • OFM Warning and Prompts – If you do not want to see the warnings/prompts you can select to suppress them by clicking Suppress All. Restore All nullifies the Suppress All request. • OFM Settings Reset – Restores all the OFM default settings. Clicking this button will cause OFM to reset all user-specified options in the Settings dialog. Group The Group tabbed page of the Settings window enables you to set global grouping parameters. Execute user procedure after grouping – Upon grouping (selecting), OFM automatically executes the associated user function (procedure). This option is primarily used for automating tasks. DCA The DCA tabbed page enables you to associate parameters/qualifiers and set the default case used in forecasting. 284 OilField Manager 2007 Fundamentals Schlumberger Public Sum individual well forecasts when grouping wells – If you have performed forecasts on individual wells and want to retrieve the forecast for a group of wells select this option. Schlumberger OFM Tools and Settings Units The Units tabbed page contains everything needed to display your project in Metric units. Select Use Metric Units in order to display data in metric units by default, and OFM will do the internal conversions. OFM does not permanently apply unit conversions to the database. Exercise 78 Grouping Data by Date Schlumberger Public 1. Clear any previously applied filter. 2. Group all the wells on the basemap (231 wells). 3. Click the Report icon to generate a report. The Edit Report window displays. 4. In the Select section of the window type the following: date, monthlyprod.oil, monthlyprod.gas, monthlyprod.water. OilField Manager 2007 Fundamentals 285 Schlumberger OFM Tools and Settings 5. Click OK. The report displays in monthly frequency. 6. Double-click on the report. The Edit Report window displays. 7. Locate the Keypad section of the dialog and click Clear. 8. In the Select section of the dialog type date, dailyprod.oil, dailyprod.gas, dailyprod.water. Click OK the report displays. 9. From the Property pane expand Report and from the Frequency list field select Monthly. Schlumberger Public 286 OilField Manager 2007 Fundamentals Schlumberger OFM Tools and Settings Date Display The Date Display tabbed page enables you to display your monthly dates at the beginning, middle, or the end of the month. NOTE: The settings made from this page do not change the monthly data. Schlumberger Public Multiply By Factor The Multiply By Factor tab enables you to modify production and injection data by either a static or dynamic (with time) factor. OilField Manager 2007 Fundamentals 287 Schlumberger OFM Tools and Settings If Dynamic is selected, factors greater than one are assumed to be percentages. Lesson 40 Data Normalization Not all wells start producing at the same time, and for many well potential studies, users want the option to bring all the wells to the same starting point. OFM can shift all the wells (entities) to the same base point (i.e., start of work-over, start of decline) using a functionality call normalization. Do not misunderstand “normalization” in OFM with a conventional understanding of “normalization” (normalized to one). In a sense, data normalization in OFM is equivalent to time-shifting data. 288 OilField Manager 2007 Fundamentals Schlumberger Public Only the variables that have the Multiply by Factor option (in the Grouping Options section of the Math tabbed page) turned on are affected and so are their derived variables. Schlumberger OFM Tools and Settings Exercise 79 Using Data Normalization 1. From the Filter pane, select Well List and right-click. 2. Select Open from the shortcut menu and load Prod_Wells98.txt. 3. Select the checkbox to the left of the Well List to apply the filter to the wells on the basemap. 4. Group all the wells on the basemap. 5. Click the Plot icon. The Edit Plot window displays. 6. Click Add Multiple Curves. The Add Multiple Curves window displays. 7. In the Category list field select UNIQUEID. In the Variable list field select Monthlyprod.oil. NOTE: This file was saved from a previous filtering exercise. If you do not have the file saved, the list was a result of a Filter by Query operation that found the wells that produced at least 50 bbl of oil at least 3 consecutive times since 1998. Run or create the query to get the result and continue to step 3. Schlumberger Public 8. Click OK. The Add Multiple Curves window closes and you return to the Edit Plot window where the multiple curves are displayed. 9. Verify that you have Date as the X-Axis variable and only one graph. OilField Manager 2007 Fundamentals 289 Schlumberger OFM Tools and Settings 10. Click OK to display the plot. (You many want to increase the curve width and move /resize the graph and legend in order to see things clearly.) 11. Notice that the wells started producing at different points in time. Now select Tools > Settings and select the Normalize Tables tab. 12. Select the Enable Normalize Tables option. 14. Leave the Ending Condition unassociated (blank). 15. Select Default for the Date Option and Filtered Wells for the Well Option. The options available from the Normalize tab are described below: 290 OilField Manager 2007 Fundamentals Schlumberger Public 13. Select the InitialProdMonth variable from the Starting Condition list. Schlumberger • Ending Condition (Optional) – Sets the data point to be displayed. On the plot, all data after this point will be truncated. This feature does not change the physical data; it simply changes the display (data retrieval time). • Date Option Default – All data is shifted to the earliest available date in the database, regardless of the variable associated in Starting Condition. • Date Option Earliest – The earliest date associated with the variable in the Starting Condition. • Date Option Latest – The latest date associated with the variable in the Starting Condition. • Well Option All Wells – Runs normalization on all the wells. • Well Option Filtered Wells – Runs normalization only on the filtered wells. • To return to normal mode (de-normalize) just clear the Enable Normalize Tables checkbox. 16. Click Normalize to execute the normalization operation now, without closing the Settings dialog. 17. Click OK to close the Settings window and view the plot. OFM Tools and Settings NOTE: If you do not click Normalize, OFM initiates the normalization operation when you click OK. Schlumberger Public Lesson 41 Data Register A data register is used to store cumulative values for a field or region to normalize data and calculate cross-table values by interpolating between tables or lookup data between tables. Data Registers are useful to compare two or more wells in a report and interpolate data between two known points. Created data registers can also be displayed on plots. The Data Registers do not provide access to data that are not in memory. They provide access to data that have been placed in memory, i.e., the data register. OFM provides a concept name Data Registers to register data and recall the registered data for subsequent calculations. OilField Manager 2007 Fundamentals NOTE: A data register is a place to store data. It is not specifically for cumulative values, calculating cross table, or lookup data between tables. 291 Schlumberger OFM Tools and Settings Exercise 80 Creating a Variable to Represent the Average Monthly Oil and Creating a Data Register 1. Select Database > Calculated Variables. The Calculated Variables window displays. 2. Click Add Variable. The Edit Calculated Variable window displays. Type @Aveinput( monthlyprod.oil). 3. Click OK. The Edit Calculated Variable window closes, and you are returned to the Calculated Variables window. Schlumberger Public 4. Type CV.AveOil in the Name field. 5. Click Close. 6. Click the Report icon. The Edit Report window displays. 7. In the Select section of the dialog type Date, Monthlyprod.oil, CV.AveOil and click OK. The Edit Report window closes, and the report displays. 292 OilField Manager 2007 Fundamentals Schlumberger OFM Tools and Settings 8. Select Blue_1:Li_1C. On an individual well level, the monthly oil production and the average oil production are the same. On a group level, you expect them to be different . The ratio of individual oil production (the well) to the average production of an entity (a reservoir which the well belongs to) determine the performance of that well compared to the average. A ratio greater than unit (1) is considered above average and vice versa. Schlumberger Public 9. Clear the filter. 10. Select Category, then Reservoir and Litmus_1. 11. Group the data and select the Report tab to view the report data. NOTE: Notice the first several records. You should have about ten wells producing at the beginning (you can check that by the @CountInput() function). If you select an individual well now, the two numbers will be the same. Thus, you would want to register one for the grouped entity and then recall the data for later calculations. 12. Select Tools > Data Registers. The Data Registers window displays. OilField Manager 2007 Fundamentals 293 Schlumberger OFM Tools and Settings 13. In the Comment field type Registering Monthly Average Oil per Well for Litmus Reservoir. 14. From the X list field select Date. 15. From the Y list field select CV.AveOil. 16. Select the Lock checkbox, the (top) register location # refreshes and registers the first memory location for Litmus_1. 17. Click OK. The Data Registers window closes, and you are returned to the report. 18. Double-click on the report. The Edit Report window displays. 19. Add @reg( 1, Date, "date"). NOTE: Notice the values of the last two variables. They should be the same. You may want to change the decimal specification to read the exact values. 294 OilField Manager 2007 Fundamentals Schlumberger Public 20. Click OK. The Edit Report window closes and the report is updated. Schlumberger OFM Tools and Settings CV.AveOil was saved to the data register; as long as the report displays CV.AveOil under the same conditions as the data register was saved, the variables will be the same. The only reason the last two columns display differently is because one displays no decimal places and the other displays two, as the note to the left states. 21. Double-click on the report. The Edit Report window displays. Schlumberger Public 22. Edit the report parameters and add monthlyprod.oil/@reg( 1, Date, “date”) to the parameter list. Click OK. 23. Increase the number of decimals in the last column. The report refreshes. Navigate through all the wells to verify the results. The second argument of the @reg() function (i.e., Date) is an output frequency (control) variable. If the variable there is not the same as the X variable being registered, in that register location (first argument of the function), OFM performs linear interpolation of the Y variable. There is no extrapolation scheme in the @reg() function. 24. Unlock the register and observe the difference. 25. Close the report but do not clear the register. OilField Manager 2007 Fundamentals NOTE: Unlocked registers refresh when the entity changes. 295 Schlumberger OFM Tools and Settings Review Questions • What five types of project settings can you customize in OFM? • What is the purpose of the Normalization function in OFM? • What is a data register and why is it useful?
