COURSE DESCRIPTION AND OBJECTIVES
This three-day course provides subsurface and well-planning professionals with a practical foundation in the geological and geomechanical principles that control pore pressure and in-situ stress in sedimentary basins. The course begins with basin formation, basin filling, sediment accumulation, and the geological and tectonic processes that influence normal and abnormal pore pressure.
Participants will learn to recognize, interpret, and predict pore pressure using well logs, drilling data, mud weight, and formation pressure measurements, followed by an introduction to in-situ stress and stress regimes. Practical applications include seal capacity and integrity analysis, maximum hydrocarbon column prediction, and the integration of pore pressure and stress conditions to define a safe mud-weight window for well planning and drilling.
The course combines lectures, practical data analysis, exercises, and case studies from Indonesia and global sedimentary basins. Participants will work with realistic subsurface datasets to develop pressure–depth interpretations, perform basic pore pressure prediction, evaluate stress conditions and regimes, assess seal capacity, estimate maximum hydrocarbon column height, and construct practical mud-weight windows. Participants are required to bring their own laptop with Microsoft Office installed, particularly Microsoft Excel, for practical exercises.
LEARNING OUTCOMES
By the end of the course, participants should be able to:
- Understand the Fundamentals of Pore Pressure and Geomechanics
- Identify and Evaluate Abnormal Pore Pressure
- Apply Practical Pore Pressure Prediction Techniques
- Characterize In-Situ Stress and Stress Regimes
- Apply Geomechanics to Practical Exploration and Drilling Problems
- Integrate Subsurface Data for Decision-Making
WHO SHOULD ATTEND
This course is designed for subsurface and well-planning professionals, including exploration and development geologists, geophysicists, petrophysicists, drilling and well engineers, reservoir engineers, geomechanics professionals and other technical professionals involved in subsurface evaluation and well planning.
WHY WE SHOULD ATTEND
Pore pressure and geomechanics are no longer specialized topics limited to dedicated geomechanics teams. They are increasingly important components of everyday subsurface interpretation and exploration decision-making.
