DINO-DO Users Advisory Council, Minutes of the Meeting of January 28th 2010
From
Mr. Klaas Maas
Agreements and assignments:
Agreements/Assignments of the meeting of September 19, 2007

(A7) Peersmann’s proposed actions to enlarge and complete the council’s composition to represent
the broad spectrum of societal interest, including public institutes and gremia like the “Technische
Commissie Bodembescherming”, are accepted by the council as an option for the future. At present
though the council will represent the NLOG users presently active, including NOGEPA, the Salt Industry and Deep Geothermal Energy exploiters, which will be approached by Peersmann.
This assignment still stands.
Agreements/Assignments of the meeting of October 08, 2008:
All agreements and assignment of 08-10-2008 still outstanding in the meeting of March 11th 2009 have
been settled since then, the last ones with the December 2009 release of NLOG.
Agreements/Assignments of the meeting of March 11, 2009:
1
Mr. Jan Wood who expects a posting at Shell London has transferred his membership to Mr. Jan Eikelboom.


(A1) Since all seismic lines have original names/codes as assigned by the companies that ordered
those lines, in the NLOG selection screens for seismic surveys these original names/codes should be
used, instead of the NITG-codes. This wish by Driessen is noted as a future assignment for Monen.
Completed?.

(A2) Giesen’s remarks on the incompleteness of DINO’s seismic archives (large numbers of the existing 2D seismic surveys of the shallow Dutch subsurface have not been stored in DINO) are noted as
new complaint (Monen).
Laid aside for future consideration.

(A3) Additional wishes from the council members for new developments in NLOG will be received by
the Chairman after the closing of this meeting. (members / Chairman).
Completed.

(A4) EBN has expressed a demand for the availability in NLOG of pre-stack seismic data. The feasibility of extracting such data will be discussed in the next meeting of the Suppliers council (Kuipers).
At the request of Harings this assignment will stand over to be discussed in the DINO-DO Suppliers Council, though Van Leeuwen maintains that DINO lacks the capacity to make the pre-stack seismic data available as requested.

(A5) The DINO-DO Users council is of the opinion that a budget of only k€ 50 for new developments
in NLOG in the year 2009 is obviously insufficient, it should be raised. The Chairman will introduce
this opinion in the next meeting of the chairmen of the DINO users councils (Chairman).
Completed.

(A6) Buik has composed a personal list of priorities for developments and improvements of NLOG to
be executed in 2009 which he will mail to Monen; he is especially interested in the availability of porosity/permeability data (Buik / Monen).
The status of this assignment is unclear.

(A7) Mr. Driessen (Total E&P) will meet with Mr. Kuipers to discuss the realisation of the transfer to
DINO/NLOG of all digital 2D seismic data files of the NCP surveys that have been executed by Total
E&P (Driessen / Kuipers).
Driessen reports that the execution of this assignment still has to be started; the data are however available
on request.

(A8) The next meeting will be scheduled for Wednesday morning October 14th, 2009 (Maas).
Completed
Agreements/Assignments of the meeting of January 28, 2010:
A1 At the request of Mr. Harings, assignment A4 of 11-03-2009 (EBN’s wish to facilitate the availability
in NLOG of pre-stack seismic data) is kept on to be discussed in the DINO-DO Suppliers Council (an
assignment for the successor of Mr. Kuipers).
A2 Mrs. Van Daalen has apologized for not having available a UK presentation on ppt sheets, the secretary will forward the UK ppt sheets as soon as possible after this meeting,
A3 Mr. Remmelts has made notes of all complaints and requests stated under agenda point 6 (Complaints, wishes and comments, nrs 1-16) and will see to it that they receive due attention.
A4 Several users have named the seismic surveys as the data of which the availability should most urgently be improved. The Chairman concludes that this wish should be tabled for discussion in the meeting
of suppliers of seismic data, which should therefore be convened.

then inform the Council on the recent (and not yet completed) reorganization of the DINO Department.

The Chairman now invites Mrs. Van Daalen to inform the Council on the recent developments in the process of transforming DINO into the national Key Registration for the Subsurface (BasisRegistratie Ondergrond, BRO). Mrs. Van Daalen apologizes for not having available a UK presentation on ppt sheets, the
secretary will forward the UK ppt sheets as soon as possible after this meeting, the Dutch version will have
to do for now:
Since the Dutch government’s decision of December 19th 2008 to transform DINO into the formal national
key registration for the subsurface (the “BasisRegistratie Ondergrond, BRO”), the year 2009 has been a
turbulent year for DINO and the stress is not over yet. To obtain a clear view of the coming changes it is
good to start with a summary of DINO’s present position: DINO is the database for all subsurface data and
information of the Netherlands and it’s continental shelve territories (The NCP: Netherlands’ Continental
Platform). In its present position DINO has to deal with a large and variegated company of stakeholders
(national, regional and municipal authorities, public and private institutions, business companies and private persons) in policy areas such as Spatial (urban & rural) Planning, Environment, Agriculture, Nature
conservation, Water conservation, (transport) Infrastructure, Energy, Public Safety, and Archaeology. The
national ministries involved with DINO are VROM (Housing, Spatial planning & Environment), LNV (Agriculture, Nature Management and Food Quality), V&W (Transport, Public Works and Water Management), EZ (Economic Affairs), BZK (Interior and Kingdom Relations) and OCW (Education, Culture and
Science). The use of DINO data by the ministries is mainly as shared information on maps. Some involvements of ministries with DINO are codified in laws and in regulations derived from laws: The EZ involvement, pertaining to the management of the deep subsurface data, is codified in the Mining Law
(Mijnbouwwet) and is also apparent in the advisory role of TNO in establishing the national energy policy
(e.g. the EZ Gas production letter of 2004 – on the policy concerning small fields, and more recently the
EZ Gas rotunda letter – the deep subsurface of the Netherlands and its NCP employed as a gas storage and
distribution centre for Europe). The involvement of VROM (the ministry responsible for establishing the
BRO) will increase in the near future. The BRO is (to become ) an important part of the national geoinformation2 services in the Netherlands. The national policy on geo-information is stated in the VROM
policy document GIDEON: Geo-information is to be a corner stone for E- (electronic) government (with a
central distribution portal for all users of digital public information, a ‘one-stop-shop’). This geoinformation will be generated and supplied by 5 key registrations (of which BRO will be one) and in that
process the EU directive INSPIRE3 has to be implemented which means that in the future geo-information
can be exchanged between national data registers. Within the system of key registrations everybody will be
able to communicate with everybody; by logging in to www.e-overheid.nl you obtain an entrance to the
key registrations and are able to see e.g. the composition of the subsurface of your own back yard. From
2012 onward we will have to present our data conforming to the European standards which means that we
have to rebuilt DINO. At the moment EU working groups are formed to make the inventory of data types
and effect their harmonisation; for the data on energy this is carried out in the European JRC (joint research centre) in Petten. This European harmonisation will also effect all deep subsurface data.
The geo-information of the Netherlands is to be structured in a so-called ‘three layer model’ of the – physical – human habitat, which differentiates that habitat in (top to bottom):
2
Geo-information (in full: geographic information) is defined as all information with spatial coordinates (establishing a location). In all geosciences and all GIS-systems geo-information has a key role. Geo-information is
also the source of all digital maps.
3
INSPIRE (infrastructure for spatial information in Europe): The INSPIRE directive aims to create a European
spatial data infrastructure. This will enable the sharing of environmental spatial information among public sector
organizations and better facilitate public access to spatial information across Europe. The implementation of
INSPIRE will be the subject of a vote in the EU Parliament in May 2010.

an occupation layer [of which the geo-information is registered in: the key registration for Addresses
and Buildings (BAG), the Kadaster4 (Basis Registratie Kadaster – BRK, the registration of land parcels); de Topographical Map (Basis Registratie Topografie – BRT), and the Large-scale Base Map of
the Netherlands (Grootschalige BasisKaart Nederland – GBKN)];
a network layer [containing all cable and pipe conduit systems above ground and underground, the
information of which is registered in the “KLIC” database (formerly of the independent “Kabels- en
Leidingen InformatieCentrum”, nowadays merged into the Kadaster and available under KLIConline)];
and a subsurface layer the information of which has to be supplied in the BRO.
This means the registration in the BRO of in the first place all geological data and information (the DINO
database) and of all soil data and information (the BIS database of Alterra); this constitutes the realisation
phase of the BRO project which starts this year and has to be completed per 01-01-2013. After 2013 and
subject to the results of cost/benefit analyses, all data and information on the environmental quality of the
subsurface and on its archaeological contents will also have to be registered in the BRO (the quality data, if
added, are expected to number about 50.000 per year; DINO will be growing fast). The introduction of the
BRO is planned in four phases: a specification phase, completed in 2009; a realisation phase (the delivery
of the software products – DINO will be completely rebuilt) the completion of which is planned for 2010;
an introduction phase (01-2011 to 01-2012) during which municipalities and provinces will be connected to
the system; and a completion phase (up to 01-01-2013) meant for readjustment and refinement of the system en and the instruction of the intended users in its use.
DINO will be completely tuned to the BRO. The introduction of the BRO will also change TNO’s role: at
the moment TNO is ‘source owner’ of (the data and information in) DINO, that role will change to registrar
of BRO. The role of data owner will shift to the suppliers, the municipal and regional authorities that will
have the legal obligation to supply the data to the BRO. The data owners/suppliers will also have the responsibility for the quality of the data. DINO as registrar will (only) be responsible for the intake and availability (delivery to users) of all public data and information of the subsurface. Intake, processing, registration and delivery of data and information in the BRO will be executed by automated web services (in the
public system of key registrations this is obligatory). The legal data owners will also have the legal obligation to be connected to the BRO; for each data type they will use only one exchange format per data type,
which conforms to the Information model ‘Bodem’ (IMBOD5) and to the Information model ‘Metingen’
(IMMetingen6) (both models are in harmony with INSPIRE). Ideally in the BRO web services will be integrated in the client processes, each mutation in a source will be processed real time (atomic data exchange
instead of bulk exchange), all specifics of the contents of the files will be accessible for the outside world
(full extraction), and all authorized suppliers will be connected to the BRO.
Mrs. Van Daalen then explains the intended conceptual architecture (de pertinent ppt sheet has to much
detail and the letters are to small to be legible on the screen): Via de “OverheidsServiceBus”7 (OSB) all
key registrations can be accessed including the BRO. The source owners (DINO, BIS, authorities, independent government institutions, and other data suppliers) deliver their data to the BRO register by direct
delivery to DINO, or using an intake portal, or using the OSB. The BRO register has an interface with the
OSB which also offers access to the other key registrations, and to a feed back facility (the “TerugMeldFaciliteit”, TMF), and also to the System Catalogue, to the Service-Register and to all authorities. The feed
back facility (TMF) facilitates the feed back process between source owner and registrar. The BRO registrar (i.e. TNO) is responsible for the QC of mutations by source owners. All public authorities that execute
Kadaster: the public registrar institute for all land lots (‘percelen’).
IMBOD (informatie model bodem) is developed by TNO and Alterra, to provide access to the databases DINO
en BIS using one portal (the integration of dinoloket.nl and bodemdata.nl) in preparation of the BRO.
6
IMMetingen (the information model for exchange of measurements, is being developed by a cooperation of
Alterra, TNO, SIKB and IDSW.

or order an exploration of the subsurface have an obligation to first check the BRO database for existing
data on the area to be explored; any faults found in the BRO data have to be reported to the registrar. TNO
will retain the ownership of the present content of DINO. From 2013 onward the BRO will gradually be
loaded. For data distribution the BRO portal will be used as will the OSB. It is intended that all government
parties use the OSB facility but EZ does not want to be involved and so the future use (or non use) of the
OSB facility by public parties is to date the subject of a discussion at a higher level of government. However most data delivered at present are from private parties. For non-government parties the existing portals,
among them NLOG and DINOLoket, will remain ‘in the air’ and available for the customers.
At the moment (in the ‘pre-BRO’ situation) DINO contains authentic data and descriptive data. For the authentic data, the owner has a responsibility for the quality and has to report back when questioned. After the
introduction of the BRO law (the post-BRO situation) the database will hold authentic data , descriptive
data, source documents and reporting models. The definition of which data will be authentic is still under
discussion (EZ for instance has vetoed an authentic status for core descriptions). The exchange software
(‘koppelvlak’, a kind of interface structure) between BRO and OSB is a very complex software construction which Mrs. Van Daalen will not try to explain. However all present users will retain their present entries to the data.
To classify the subsurface data, BRO will know four object types:
Explorations: locations in the Netherlands or on the NCP where the composition and/or structure of
the subsurface has been explored by an observation/measurement in a point along a line or in a surface;
Models: schematisations of the composition/structure of the subsurface; these comprise all maps and
spatial models;
Infrastructures: Man made (auxiliary) constructions in the subsurface like wells or mine shafts (no
public utility conduits), including virtual constructions like monitoring networks;
Licenses: Licenses conferred by a legal authority, for specific exploitations or uses of the subsurface.
These four object types are each subdivided in (sub)types (exploration types, model types, infrastructure
types, licences assigned to the respective laws) which again are subdivided into their basic subtype units.
Not all subtypes will be included in the BRO. Of interest to this Council is the exclusion from the BRO, in
compliance with an explicit wish of the Ministry of Economic Affairs (‘EZ’), of the Deep Subsurface Models of the Netherlands (‘DGM-diep’) and the NCP. Mrs Van Mourik - van der Bruggen asks for EZ’s motivation and the possible implications of such exclusion. Mrs. Van Daalen has no insight in EZ’s motivation
but stresses that the deep subsurface models will remain part of DINO and will remain accessible in
NLOG. However when the deep subsurface models are not considered part of the BRO and as such are not
mentioned in the BRO law, their future funding (for maintenance and innovation) may be jeopardized.
Doornenbal observes that for the near future EZ will finance the deep subsurface models; for the distant
future nothing is guaranteed. Mrs. Van Daalen then finishes the presentation of the BRO content: all mining law licences will be registered in the BRO and this includes the licences for underground storage of
substances, fluids, gasses and geothermic energy in the deep subsurface. Geothermic use of the shallow
subsurface (in heat/cold doublets) is as yet excluded but the expectations are that this subsurface use will in
the future also be subject to licensing.
Mw. Van Daalen then explains the impact of the BRO introduction on the organisation structure of the
DINO department. The department will have to adapt; it’s processes will be drastically automated and executed with less employees. A new organisation model has been introduced: The top structure is self evident: There is of course a Head, with a small staff: a policy unit of 2 fte (1 fte for national policy and 1 fte
for international policy), 1 fte information analysis and 1 fte quality management. The body of the department henceforth consists of three pillars:
- The Service desk: the present crew will be enlarged to 5 fte including a trainer to instruct the clients in
the use of BRO;
- The Data Management group: is to be reduced to 19,5 fte, their main occupation will be the intake and
processing of new data, archive coordination and conservation of cores and samples (storage in the
“Kernhuis”). To this group also belong the 3 account managers: for the geological data of the shallow

subsurface (Mr. Mutsaers); for the groundwater and soil data (Mr. Van der Meij); and for the deep subsurface (Mining Law) data (this account manager is being recruited);
- And the ICT group (22 fte) for the development of the architecture and the management of the software
system. (this group was transferred to the new organisation largely without changes).
Van Leeuwen explains that the QC of data will to a very large extent be automated. Under the regime of the
BRO the quality of the data will be the responsibility of the data owner (the ‘source owner’; the formal;
source owner of the mining law data is the ministry of EZ). An urgent task will be to harmonize the data
formats in DINO with the requirements of the INSPIRE directive. The mentioning of INSPIRE prompts
Mrs. Van Mourik-van der Bruggen to remind Mrs Van Daalen of the intention (communicated in the most
recent Chairmen’s meeting) to introduce a uniform naming system for all boreholes in DINO. Mrs. Van
Daalen acknowledges that this intention is not yet effected: The introduction of new formats for subsurface
data conforming to the INSPIRE requirements is a major negotiation with all EU countries involved; DINO
tries to participate in all discussion groups. It is a difficult and time consuming effort, to establish a common ground vis-a-vis INSPIRE and to agree on a joint direction.
The present practice of the ‘steering by demand’ (“vraagsturing”) of the Geo-Information Programme, as
effected by the Council for the NITG and its Geo-Information Committee (GIC), will, under the BRO, also
have to change, as will the organized representation and consultation of the users. Mrs. Van Daalen stipulates that at each stage of the development of ideas, the present user councils will be informed of intended
changes and asked for their opinions. She however expects that for the users of the mining law data represented in the present council, these changes will be negligible to none at all.
Mrs. Van Daalen now finishes her presentation, again she apologizes for the fact that her ppt sheets were in
Dutch, a UK version being not yet available. Maas will distribute the UK version as soon as possible after
this meeting (see above: action A2).
Mrs. Saras now asks when the new architecture and web services are to be expected. Van Leeuwen explains that in the preparation of the key register, during the period 2010-2011 the focus will be on the shallow subsurface data; the deep subsurface data are, and will remain, covered by the Mining Law. For the
deep subsurface data there exists an international user group (the E&P industry) practicing a form of industrial standardisation. For the data of the shallow subsurface , standardisation is not the rule but the exception.
The Chairman now concludes that at present no major changes are expected in the management of the deep
subsurface data or their availability in NLOG. The deep subsurface models will still be updated and Mrs.
Van Daalen as Head of DINO will inform this council of any changes once they become apparent.
Mrs Van Daalen acknowledges this summary of her communications. She adds that as for the implementation of the INSPIRE directive, the publication of the INSPIRE annex presenting the formats for subsurface
data [geology, soils, and contaminations of the shallow subsurface (the most problematic category)] is expected for the year 2012.
The Chairman now reminds the council that about a year ago the DINO department, after a request in the
Chairmen’s meeting, organized an informative meeting for NOGEPA8 on the introduction of the INSPIRE
directives and the expected consequences for the management of E&P data. NOGEPA is aware of the recent developments and will keep a close observation.
Mrs Saras then asks whether it is possible to subscribe to a DINO/BRO web services to be automatically
notified of the ‘publication’ in NLOG of any new wells, seismic surveys or other new data of interest. Van
Leeuwen expects that such services may be offered in the future but is at present above the department’s
capacity.
This concludes agenda point 3 and 4. The Chairman now proposes a short break.

Complaints, wishes and comments by DINO-DO Users, including news items from individual users
of interest to the council.
No written communications have been received. The Chairman proposes a table round to give all members
the opportunity to state their requests and comments:
Kluin has several:
1. Furnish more frequent updates of shape files; also add extra map updates (of wells, shipping lanes, military regions, wind mill licenses, and so on);
2. Present digital images of the wells with easy access to all boreholes within the well configuration: the
original hole as well as the sidetracks, in the present situation the sidetracks are not shown when an
original borehole is selected.
3. Offer a longer list of search results per page; show all results together (in the present situation results
are presented on pop-up screens with 10 results per window); also indicate on the first page which kind
of well data is available.
(Remmelts here comments that the in next release of NLOG (due March 5th) an XLS file will be available
to download all search results.)
4. Be more specific when indicating the type of seismic survey: distinguish between a ‘migrated stack’
and an ‘unmigrated stack’ instead of just a ‘stack’; supply the processing parameters as well.
Harings asks whether the output spreadsheet which is being developed for NLOG will be a pre-defined
sheet or a sheet that will allow the user to make his own specifications. Remmelts answers that the spreadsheet will be predefined but the user may remove the categories he doest not need.
Mrs. Pubrick has two request:
5. That in NLOG next to the field codes also the full names of the fields will be shown.
6. That the well listings clearly indicate to which field a well is targeted.
Mrs. Vyse also has some requests:
7. Please indicate on the borehole map the bottom hole locations (especially in case of deviated wells);
8. NLOG publishes a list of new drillings while they are being drilled. Is it possible to publish also a list
of new seismic surveys while they are being shot?
(Remmelts here comments that at present this information is not available to DINO but may be available in
the future.)
9. Could the winning plans (production plans) be shown in NLOG and could they be attached to the respective fields?
(Remmelts expects that this service will be available in the near future, the ITC group is working on it.)
10. There are inconsistencies and discrepancies in the listings of fieldnames in different compilations (different names for the same field are in use on the map, in the annual report and in the production figures). These inconsistencies confuse the user as to which field is which; they should be removed.
(Remmelts fully agrees to this request but points out that NLOG, on its front page, has a Contact button for
“questions, wishes and complaints” designed for just this kind of requests. If that button is used to communicate complaints, the NLOG team can start straight away to solve the problem. A complaint received
via the contact button is answered as ‘received and under consideration’ within three working days; the
NLOG team tries to solve any forwarded problem within three weeks.)
Rongen has a related set of requests:
11. File naming should be consistent and according to the content of the (ZIP-) file;
12. Don’t change file names; companies may have processes in operation connected to file names;
13. Is there a way to track the status of a complaint taken up by DINO (received, under treatment, solved)?
Driessen reports that two weeks ago he has, successfully and in one try, downloaded a LIS/LAS file from
NLOG:
14. His present request is that it be also made possible to download directly from NLOG the files of 2D
seismic surveys (profiles); till now he had to order such data by email.

15. Driessen also wants to know which address to use to send new logs and seismic data to TNO; till now
he did send them to Mr. Meinster. Is there a TNO address that can be published on the NLOG site?
Mrs. Heijnen inquires about the possibility to download LIS/LAS files in a ZIP-file. Remmelts expects that
this assistance will also be included in the next release of NLOG.
Mrs. Saras refers to the memo of Mr. Monen (see the Attachment,):
16. Of the issues to be released in the December 2009 version of NLOG, the items 4 (Facilitating Googlelike search within NLOG), 5 (Introducing RSS feeds in NLOG) and 8 [The visibility in the NLOG portal of newly released wells, as well as of other changes in (the contents of) NLOG, should be enhanced] have not yet been realized. Mrs Saras would like to be able to search in NLOG on modified
dates and other mutations.
(Remmelts acknowledges these omissions which hopefully will be repaired with the NLOG release of
March 2010.)
Mrs. Van Mourik-van der Bruggen concurs to the complaints of Mrs Saras. As Chairman however she
wishes to compliment the DINO department for all changes and improvements in NLOG that have been
realized since March 2009. A great deal of work has been done and lots of changes and improvements
were effected. Mr. Remmelts has made notes of all complaints and requests stated above and will see to it
that they receive due attention. With that this agenda point is closed. The Chairman now tables agenda
point 7.

Presentation and discussion of the parts of the Geo-Information Programme 2010 relevant for the
users of the deep subsurface data and information.
Van Leeuwen will inform this council on the 2010 programme for the management in DINO of the deep
subsurface data and of the intended innovations in the organisation of the data management. His presentation has 4 main items:
- The new organisation of the data management;
- The BRO-project (the key register) in 2010;
- The processes in transition in 2010; and
- The processing of the archives in 2010.
Formerly al activities within the DINO data management group were labelled “processes”, meaning “not
projects” (projects are activities that are executed following a fixed schedule to realize the project plan
from a start date to a delivery date) but activities with a (semi)permanent character, like the intake and processing of new data. For 2010 within the data management three groups of separate activities (processes)
are distinguished:
- BRO projects (projects to realize the BRO): Data projects resulting in web services;
- Processes in transition: The processing of new data of the data types that will be included in the BRO
as of January 1st, 2013;
- Archives (and non BRO): The processing of archive records (paper) and “old” datafiles (and also the
processing of new data that will not be included in the BRO).
A BRO data project has as deliverable the web services for the exchange of a specific data type in the
BRO:
- The content of the data type has to be newly specified: the question “what ought to be the content of
the data type?” has to be answered. This will be a subject of interaction and discussion between you
(suppliers/users) and us;
- Then the data(base) model will have to be redesigned;
- The exchange formats have to be (re)defined;
- Information services (web services) have to be developed;
- The DINO data then have to be converted.
In all these steps DINO should like to be in agreement with its users and suppliers.
The BRO data projects planned for the deep subsurface data in 2010 are:
The data project “Production wells” (incl. the realisation of web services for production figures); and
Our reference
TNO-034-UT-2010-00172 js

The data project “Licences MA”, with the specification of the data content and the validation.
The processes in transition (for the deep subsurface data which are to be included in the BRO) for 2010 will
concern: Seismic surveys, Bore-hole data; Models and maps; Licences MA; and, Production well data. The
focus of the data management is on keeping the business going and in the same time preparing ourselves
for the introduction of the key register (BRO). This preparation for the BRO means (among other things):
Realisation of automation and standardisation in the data management work processes;
The streamlining of the intake of new data; and
The improvement of the quality of the database.
The Archives (and non BRO) activities considered come under two headings:
The processing of samples and archives [the collection present in DINO’s physical core repository
(the “Kernhuis”) and its collections of microscopic slides and (mineral) residues]; and
The processing of archive records (paper) and “old” datafiles (in cooperation with the Big 4: NAM,
GDF Suez; Total and Wintershall); for the year 2010 these concern notably the activities on the following subjects : the Log scan project; LIS and LAS files; Directional surveys; Core analysis data; 2D
seismics; and the Scanning of reports.
The 2010 plans for these archive projects are:
The completion of the Log scan project in the 2nd quarter;
For the LIS and LAS files: the processing of NAM and Wintershall files will be completed in the 1st
quarter;
For the Directional surveys: the processing of the NAM files will be completed in the 1st quarter (the
Wintershall files have been processed already in 2008);
For the 2D seismic surveys: the possibility to define a project is being explored;
For the Scanning of reports no specific project is planned as yet.
As for the Core analysis data: the Wintershall and NAM data have been completed in 2009.
This ends the presentation of Van Leeuwen who, after receiving the chairman’s compliments, asks for
questions, comments and priorities.
Kluin suggests that it would be a better strategy to store all available data in the database before we start
optimizing the quality of the data that are already in the database.
Harings states that EBN trusts DINO to inform its users on the implementation of the INSPIRE directive
and its consequences for the users, and, more in general EBN stresses the importance of maintaining the
quality of the data and the services of DINO at its present level at least.
The Chairman agrees to EBN’s last priority: the systems performance including all services should be
maintained it its present level at least, this is the essence of the position of the chairmen’s meeting of the
DINO user councils; the Chairmen’s meeting has advised that it hopes to see the BRO ambition realized
but without sacrificing the present levels of performance and services.
Mrs. Van Daalen agrees on the importance of a continuation of service levels that satisfy the customers.
She must however point out that for the transition from DINO to BRO no extra budget is allocated; the entire operation has top be planned and executed within the budget limits as now exist. For this reason the
intake in the BRO of archaeological data and the data on soil contamination/sanitation has been postponed
till after 2013, there will be extra budget then for the intake of these data. For the moment however we hear
no specific complaints.
The Chairman now asks council members to state their needs for prioritisation. Several users name the
seismic surveys as the data of which the availability most urgently needs to be improved. The
Chairman concludes that this wish should be tabled for discussion in the meeting of suppliers of seismic
data, which should therefore be convened. Having thus concluded this discussion she now tables the
presentation of the 2010 mapping programme for the deep subsurface by Mr. Hans Doornenbal.
Doornenbal will make an effort to fit his large presentation in a modest time frame:
Stakeholder interests for deep subsurface mapping focus mainly on six application areas: Mining (production of oil, gas, coal, salt etc.); Geothermal energy; Underground storage (of gas – as buffer stock; of CO2 –
as storage of waste; etc.); Subsidence; Climate, environment and safety; Spatial planning and management.
Our reference
TNO-034-UT-2010-00172 js
Page
12/14
Stakeholder groups are: Governmental bodies (ministries, provincial authorities, municipal authorities);
Planning bureaus; Subsurface users (E&P industry, Salt miners etc.); Consultants and advisory offices;
Small and Medium Enterprises (SME’s); Research and education institutes; Society at large.
The subsurface should be mapped to obtain knowledge/understanding, needed in policy development;
needed for commercial applications; for purposes of education, for study and research; and for the product
development of DINO.
The last years have seen a shift from the conventional use of the knowledge of the deep subsurface to new
areas for the application of deep subsurface mapping products: the sustainable exploitation/use of the subsurface by: production of geothermal energy; storage of gas and CO2; the discovery of unconventional gas
resources; and the application of subsurface knowledge in the areas of climate and safety. To satisfy conventional and new applications technical needs have to be met. This means knowledge of the structure and
properties of the deep subsurface (in data and models), knowledge of conditions and processes of generation and transport of hydrocarbons (e.g. prospectivity, risks and opportunities), knowledge of climate, environment and safety (e.g. forecasts of subsidence, of effects on the environment), and making available the
deep subsurface data and knowledge for policy support tools.
Doornenbal then summarizes the deep subsurface mapping programme executed in the period 2005-2009.
This programme had its main focus on the needs of knowledge of the deep subsurface under the offshore,
existing within the E&P industry. The mapping was concerned with the geometry & structure, properties
and processes, of and within the formations. There was also attention to paleo-environment and paleoclimate and the subsidence processes of the land territory of the Netherlands (this part of the programme
was carried out in collaboration with the shallow subsurface mapping programme).
Projects executed in 2009 were
The mapping projects KARNCP2 (mapping of the deep subsurface of the offshore area) and DGMDIEP [the updating of the entire (onshore and offshore 2,5 D model deep subsurface model including
the assessment of its reliabilities (uncertainties)];
THEMAKAR [thematic mapping (modelling) of subsurface properties (T, P) and dynamics (burial
history, maturation, migration)];
BODDAL (the modelling of the subsidence of the land territory);
XBORDIEP (our part in the international mapping programmes – atlas projects – of e.g. the Southern
Permian Basin, and, as a follow-up in 2010, the mapping of gas shale occurrences in Europe);
DINO-GEOBIO (geobiological research and support of the mapping projects);
DINO-QCDIEP (the support and quality control of the database management for the deep subsurface
data).
Doornenbal now gives a more detailed presentation of the KARNCP2 project: this mapping has been conceived and executed as a mapping of NCP-subareas delineated as structural geological units (e.g. Terschelling Basin & S. Central Graben; Ameland Block; etc.); the prioritisation of the sequence of the mapping of
these sub-areas was according to the interest of the industry combined with the availability of the data
(years of data release); the products of this mapping are: a 3D geological frame work (essentially the depth
and thickness maps of the main formations); the 3D models of the petrophysical properties: parameters like
P, T, velocity and others; and the 3D models of the petroleum systems. The 2009 KARNCP2 programme
concluded the NCP- deep subsurface model with the mapping of the subareas F (Broad Fourteens + West
Netherlands Basins) and G (London-Brabant Massif + Winterton High). This mapping is now almost finished; the geometrical model of the NCP deep subsurface should be ready in Sept. 2010.
The Deep subsurface mapping programme for the years 2010-2012 is structured as follows:
In the DINO-QCDIEP project (1) reservoir data and other geological property data are gathered, analysed
and disseminated, for use in, among other things, the 3DMapping project (2) (mapping structures, properties and uncertainties); in the 4DModelling project (3) (modelling the dynamic processes, e.g. maturation,
migration and accumulation of fossil hydrocarbons); and in the BODDAL project (4) (modelling the subsidence of the land territory of the Netherlands). These three projects also exchange their results to be used
as new input. The DINO-GEOBIO project (5) generates geobiological data, interpretations and analyses
which are also used in the 3DMapping project and in the 4DModelling project. On the one hand the map-

13/14
ping programme for 2010-2012 guarantees the continuity of current programmes; on the other hand there is
a shift to new application areas based on new questions which generate new needs for data and knowledge:
Onshore these new questions concern the knowledge of the ultra deep and simultaneously the shallow formations (Tertiary); an upgrading of knowledge is needed to answer new questions from the application areas of deep geothermal energy, of carbon capture and storage (CCS) and of unconventional gas resources
(shale gas); there is also a new emphasis on dynamics (processes, prospectivity and forecasting/planning).
The deep subsurface mapping is conceived as a part of the integral Geo-Energy research programme within
TNO, to be adjusted to the needs and priorities of the other research teams.
Doornenbal now details the contents of the 5 projects (mentioned above) that constitute the Deep Subsurface programme (for this specification the reader is referred to Doornenbal’s ppt sheets). This detailed
treatment is concluded with an application matrix that sets off the project deliverables against the main application areas.
Doornenbal then offers the council an overview of a different category of mapping projects: the production
of international thematic geological atlases which are the deliverables of programmes/projects by international consortia of geological surveys and interested industry partners. These international atlas projects
have a mixed financing: some are entirely paid for by sponsor consortia, others require a ‘contra-financing’
which in the past has been allocated from the GIP-budget, e.g. the GIP-project XBORDIEP. In the past,
several international atlas projects have been concluded. At present two project are being executed: the
Southern Permian Basin Atlas (SPBA, 2005-2010) which will be completed in 2010; and the European Gas
Shale data compilation (GASH, 2009 – 2012) which was started last year. A future plan concerns the compilation of a petroleum geological atlas of North Africa (NAPGA 2011-2015).
The GASH atlas project, sponsored by an international consortium of 7 E&P companies and several national geological surveys, addresses the fact that a European database of black shale occurrences does as
yet not exist. Its goals are:
- to compile a database of the black shale occurrences in Europe to enable the production of shale gas;
- to offer access to key well and seismic data for further research;
- to compile, in a web-serviced GIS database, the important characteristics for shale gas exploration (e.g.
thickness, total organic carbon contents, types of organic matter, maturity, mineralogy, etc.);
The Petroleum Geological Atlas of the Southern Permian Basin Area will be published in 2010 as a printed
full colour atlas and as a GIS product including databases and GIS maps available as a DVD or as a webbased interactive GIS viewer. Doornenbal enlarges on the quality and diversity of the SPBA deliverables
which are very attractive indeed (among other things the subcrop map of the pre-Quaternary; the compilation of all seismics and wells used for the SPBA database; the depth map of the Zechstein base; several 3D
models; the occurrences of source rocks and main reservoirs; the reservoir facies distribution map of the
Lower Slochteren Formation; the petroleum provinces related to Paleozoic source rocks; etc.); we refer our
readers to the powerpoint sheets of Doornenbal’s presentation.
The Atlas projects are useful in their effects of unifying data presentation and nomenclature across national
boundaries; this goes for the stratigraphic nomenclatures and correlations; for the mapped seismic horizons,
and the tectono-stratigraphic charts. The atlas offers an easy and inexpensive public access to these unified
data and models and also offers an easy way for linking to scientific papers, to commercial datasets and to
key-persons (in-kind authors). In this the Atlas supports the E&P industry to fully develop the reservoirs:
careful data-integration and geoscientific effort will discover new and increase the existing reserves. Atlas
projects also function as stepping stones for (commercial) follow-up projects.
The chairman thanks Mr. Doornenbal for his presentation; in view of the advanced hour questions are to be
answered after the closing of the meeting. The chairman tables the next agenda point.

Subject
State of affairs NLOG portal
Over the past 6 months the DINO-team made efforts to realise the wishes expressed by the DINO-DO Users Advisory Council.
The realisation of a part of these wishes can be found in the December 4th release of the NLOG portal. In
fact two new releases are planned, the first as mentioned above and a next release in the beginning of 2010.
Parallel to improving the existing portals, DINO has started the preparations of the implementation of the
Key Registration Subsurface of the Netherlands (BRO). With the architecture of the BRO a data distribution portal will be provided and that portal is considered to be the successor of NLOG and DINOLoket. To
ensure that the design of the new portal has a solid foundation, DINO started a usability study immediately
after this summer, so the way this portal will be used will meet the wishes of the future users as much as
possible.
At the request of the DINO-team a number of members of both the DINO-DO Users Advisory Council and
the DINO Users Advisory Council Shallow Subsurface have made a contribution to this usability study, by
participating in a usability workshop.
Structural improvements of NLOG will be incorporated in the design of the new portal as much as possible.
In this memorandum the state of affairs concerning NLOG will be dealt with.
The division below is used to present the results:
1.
List of issues settled with the release of the April 25th, 2009 version of NLOG
