About the course

This course will provide a better understanding of pressure characteristics found in the subsurface. Delegates will be able to defi ne the fundamentals of pore pressure, fracture pressure, and overburden pressure as well as earth stresses. This course will also cover the mechanism of how abnormal formation pressure is developed and its important relationship to the evaluation of hydrocarbon generation and migration. This course will focus on providing the methodologies and techniques available in evaluating formation pressure both qualitatively and quantitatively. Topics will include methods of pre-well prediction using seismic and basin modelling as well as evaluation using trend analysis techniques and pore pressure indicators. This will be supported with case studies and exercises throughout the sessions. Delegates will learn how to use an integrated approach to evaluation using subsurface data and drilling events to fully understand fomation pressures.

You will learn

• Understand the different formation pressures – pore, fracture, and overburden pressure
• Calculate pressure gradients and apply to casing placements, formation pressure plotting, and equivalent mud weight plotting
• Determine how hydrocarbon generation and migration is infl uenced by formation pressure
• Master the evaluation and calculation of subsurface pressures through both quantitative and qualitative methods
• Identify the critical data requirements for pore pressure prediction and evaluation
• Understand hazardous events of infl uxes and kicks during drilling operations
• Integrate subsurface data & driling events, control data quality, identify non-pore pressure related hole problems, and understand the behavior of data before making any prediction analysis.
