Course descriptionThe principal objective of the course is to teach participants how pressure data relate to the safe and efficient exploration and exploitation of petroleum reservoirs.Overpressure is experienced in most sedimentary basins where reservoirs are associated with fine-grained lithologies (such as shales), in particular at depths of 2.0km or greater below sea-bed.Recent advances in the understanding of overpressure, in particular the magnitude of overpressure resulting from each of the main mechanisms under realistic basin conditions, gives improved confidence in estimating pore pressures. The course teaches participants:
- Pore pressure prediction - methods and limitations
- Recognition of abnormal pressures and principal causes
- Influences of abnormal pressures on trap integrity, sealing capacity, reservoir quality and maturation/migration efficiency in petroleum systems
Course content
- Overpressure: worldwide context, origins and mechanisms
- Pressure data and data display - use of pressure/mudweight vs. depth plots
- Determination of fluid gradients
- Pore pressure prediction - seismic, wireline, drilling and modelling methods, strengths and weaknesses, limitations and pitfalls
- Influence of overpressure on the petroleum system (trap integrity, reservoir quality, source rock maturation and petroleum migration)
- Relationship between overpressure, seals and column heights
- Compartmentalisation of overpressured reservoirs - fault and seal characteristics
- Overpressure in deep water, including well design issues
Case studies used in the course are mainly from the Gulf of Mexico, North Sea, and South East Asia basins plus other classic overpressured basins such as South Caspian Sea, West Africa, Trinidad and mid-Norway.
Training instructor The training courses we offer are instructed by the Managing Director of GeoPressure Technology, Dr Richard Swarbrick, Dr. Richard Lahann and Dr Phillip Clegg. As a world expert in oilfield pressures, Dr Richard Swarbrick is also an instructor for the Geoscience Training Alliance and the AAPG Continuing Education Program. Dr Richard Lahann is an independent consultant with a long-term relationship with GPT. He had 23 years experience with ConocoPhillips, was responsible for fluid and fracture pressure prediction and drilling support for many international wildcat wells and is currently a GPT consultant and associated with the Indiana Geological Survey. Dr Phillip Clegg joined GPT in 2006 and has been involved with major projects in the North Sea, Mid Norway, Barents Sea, Black Sea, Gulf of Mexico and NW Australia. Phillip is the GeoPressure technology training coordinator and main adviser and trainer for PressureView, PPM and PPC software.
Who should attend?
This training course is designed for geologists, geophysicists, petrophysicists and reservoir/drilling engineers with an interest in overpressure and high-pressure reservoirs, i.e. anyone who wants to understand overpressure and to know about the tools to predict it ahead of the bit. A familiarity with oilfield practices will be an advantage.
The Pressure and Overpressure in the Subsurface course is available as an inhouse presention at a client's offices or as a public course at the Ikon Science Training Centre.
