Pressures and Overpressure in the Subsurface

Course Outline:

Overpressure is found in most sedimentary basins, so understanding subsurface pressures and their effects on the hydrocarbon system is a key input into developing successful exploration strategies, efficient well planning and ensuring the safe and effective exploration and exploitation of petroleum reservoirs.

The main objective of this course is for attendees to learn how pressure data affects the safe and optimal exploration and exploitation of hydrocarbon reservoirs.

The course is designed for geologists, geophysicists, petrophysicists and reservoir/drilling engineers who have an interest in, or need to utilise pressure data in their workflows, and wish to gain a deeper understanding of the relationships between geology and overpressure.

Participants will learn how to:

• Analyse pressure data
• Calculate overburden and fracture gradients
• Use industry standard techniques to predict pore pressures in the pre-drill environment

Plus this course also covers:

• Well planning
• Hydrodynamics
• Seal breach risk

The course is presented as a combination of PowerPoint based lectures and practical exercises, and familiarity with oilfield practices will be an advantage.

This course has been officially endorsed by the Geological Society of London.
