Course & Workshop

March 12 – 16, 2023

Instructor : Stephen Occoner (Ph.D.)
Geopressure Advisor UK

WHO SHOULD ATTEND

Geologists, geophysicists, petrophysicists, engineers and drillers

Course Outlines

The principal objective of the course is to teach participants how pressure data relate to the safe and efficient exploration and exploitation of petroleum reservoirs. The course teaches participants:
• Pore pressure estimation – methods and limitations.
• Recognition of abnormal pressures and principal causes
• Influence of abnormal pressures on trap integrity, sealing efficiency for HPHT wells, reservoir quality and maturation/migration efficiency in petroleum systems.

The course is a mixture of short lectures, with sample exercises and “hands on” with pressure data and case studies. Material for the course will include many of the classic overpressure area such as Levant Basin, Nile Cone and Red Sea.

INSTRUCTOR PROFILE

Steve is a GeoPressure domain expert who has also been involved in many 100’s of projects globally, ranging from basinal studies and exploration risking to well planning/design and field assessments. He has extensive experience in SE Asia.

He has been involved in knowledge transfer and has taught more than 70 courses including bespoke courses for companies focused on integrating G&G, asset and drilling teams.

He has been instrumental in developing “Best Practice” workflows, has been involved in R&D to help reduce uncertainty in pore pressure prediction, and has integrated pore pressure with other disciplines such as rock physics and geomechanics.

He has written and been co-author on over 50 published papers.
