Final test Course review and wrap up Day 1 HPHT History and Challenges and the Geological Settings Defining the HPHT Environment HPHT Challenges and associated Standards and Practices Geology in the HPHT Environment HPHT Reservoirs On the first day we will set the HPHT environment by looking back at the history of drilling these deep hot wells. The class will be presented with the challenges associated with the HPHT environment and look at what standards and regulations apply to these HPHT wells. This is followed by a more detailed introduction of the geological aspects of the HPHT wells. Pressure ramps, increased temperatures and the various issues associated with HPHT geology will be presented. Next participants will look at the overburden, pore pressures, fracture pressures and temperatures associated with HPHT as this explains the critical differences between HPHT and normal drilling operations. Day 2 Well Design Casing Design and Tubular Selection Shoe Placement Annular Pressure build up and Thermal De-rating Casing Wear, H2S and CO2 Effects Cementing Challenges and Practices The second day we look at the well design aspects of HPHT wells. Trajectories, together with casing design and the associated issues in these high temperature environments will be addressed. Annular pressure buildup as well as temperature effects on the tubulars will be presented. Candidates will then presented with the sour gas effects in HPHT environments and then we look at the challenges and solutions when cementing HPHT wells. Day 3 Fluids and Well Control Drilling Fluid Aspects Gas Solubility Elastomers Well Control, Ballooning, Wellbore Breathing Gas Expansion Well Control Procedures On day three, participants will be introduced to the fluids and gasses encountered in HPHT wells. The aspects of drilling fluids and reservoir fluids are addressed and issues such as temperature stability, gas solubility, compressibility, elastomer ratings and operations aspects of drilling fluids will be covered. Once the fluids are understood we move onto the well control aspects, where we look at gas expansion, ballooning, losses, well control procedures and cover some of the operational aspects such as tripping, stripping and making connections. Day 4 Rig Surface Equipment and Drilling Operations Surface Equipment for HPHT Downhole Equipment Challenges Managed Pressure Drilling Finger Printing and Drilling Practices Contingency Planning Well Control Emergencies During the fourth day participants will take a closer look at all of the surface and down hole equipment that is being used in HPHT drilling operations. We will see why rig equipment as well as downhole equipment needs to be reviewed, inspected and selected based on the specific well requirements. We then look at the drilling practices and drilling technologies that are being used in HPHT wells, this includes Managed Pressure Drilling. The class then moves on to contingency planning and well control emergencies and this will introduce the candidates to aspects of emergencies and the various well control issues that can be encountered whilst drilling HPHT wells. Day 5 Completions and Well Testing HPHT Completions Design Considerations Component Selection and Specifications Tubing Leak Contingencies HPHT Well testing Operational Testing Considerations Well testing Safety The final day will be spent looking at completion and well testing issues for HPHT wells. Participants will discuss what needs to be addressed for completion and testing operations and the safety aspects associated with production of HPHT wells. The class will finish with some examples of challenges that have been encountered when producing HPHT wells. -----------------------------------------------------------------------------------------------------------------------------------------Day 1 Day 1 - The Well Construction Process Drilling purpose, where it fits into the Exploration and Production (E&P) process and its value. Exploration, appraisal, and development drilling Drilling as a project and key control tools Introduction to Drilling Mechanics On the first day, participants will learn about the well construction process. This will cover topics such as where drilling fits into the E&P process, what information can be obtained from drilling, and the exploration, appraisal, and development of a well. Well costing, AFE, and drilling operation procedures will be discussed as well. The day will conclude with an introduction about drilling mechanics Day 2 Day 2 - Drilling Fluids and hydraulics Functions of drilling fluids Composition of different type of fluids Hydraulics Rheology The second day will focus on the basics of drilling fluids. Participants will learn about the functions of the different drilling fluids as water based, oils based, synthetic based , air based, Air/water and Air/polymer. Drilling hydraulics and rheology will also be covered on this day, key for an optimal engineering. Day 3 Day 3 - Casing Design and Well Control Casing Manufacturing Process Casing Properties Casing Design Wellheads Well Control This day will focus firstly on casing design, both from an engineering and an operation perspective. Design concepts will be covered for a wide range of straightforward, as well as hostile environments. The course will examine the nomenclature of casing design, manufacturing processes, material properties and material selection. The theory of burst, collapse, and axial loading will be discussed, along with design policies and procedures. Important API specifications and other industry standards will be discussed in order for the participants to become familiar with these documents. Casing setting depths and depth design concepts will also be covered, key for an optimal engineering. This day fill follows with Wellheads, Well kicks, basic calculations required to kill a well, and the main functions of the BOP system will also be covered. The day will end with participants learning about the difference between a blow out and a well control situation. Day 4 Day 4 - Cementing and Rig Systems Cement purpose and additives Primary and secondary Cementing Casing hardware Rig Systems The importance of effective cement placement will be taught, as well as the hardware used to accomplish quality primary cement jobs. Cementing additives, Mud removal methods, techniques, and systems will be covered so that the participants will be able to recommend appropriate methods for their wells. Following with the day Rig systems description will continue, key variables to design the hoisting, rotary and circulation system will be touched to enhance the student skills to choose the most optimal tools. Day 5 Day 5 - Rig systems continuation, and completion and fishing introduction The well control system, its components and calculations about its limitations The power system, its components and calculations about its limitations The Automation system, its components and key concepts Completions introduction Fishing introduction We'll be spending the final day highlighting the importance of each one of the characteristics of the well control rig components. Students will be more familiar with several new drilling concepts and will link it all, in key concepts and rig elements used to drill while in every operation a safer well. The day will continue with the power system in which all the efforts are summarized. All the energy needed to drill an specific well design is calculated knowing about the components details. Further the automation system, we'll drive the student thru digital Intelligence concepts and robotics applied to the rig. At the end we'll make a n introduction about completions and fishing operations.
