1 Formation Pressure Prediction & Evaluation Master formation pressure evaluation to facilitate effective well design & reduce drilling risks, NPT, and associated costs 17th AUGUST st AUGUST 2015 at BALI, INDONESIA PetroSync Distinguished Instructor: TIM HERRETT Founder & Principal Consultant, Tim Herrett Ltd Over 35 years of experience in the Oil & Gas industry both in Operations Geology & Wellsite Operations He is a recognized expert in formation pressure evaluation in BP, ExxonMobil, and BG His major clients include Exxon Mobil and BP in Norway, Brazil, Turkey, and Egypt (since 2001) Worked on High Pressure & High Temperature wells for ExxonMobil & BP (since 2000) Authored Operations and Wellsite Geology procedure manuals for ExxonMobil Exploration, Development, and Production Companies in Norway and Houston Course Objectives Understand the different formation pressures - pore, fracture, and overburden pressure Relate the significance of earth stresses and relationship to formation pressure issues Calculate pressure gradients and apply to casing placements, formation pressure plotting, and equivalent mud weight plotting Determine how hydrocarbon generation and migration is influenced by formation pressure Master the evaluation and calculation of subsurface pressures through both quantitative and qualitative methods Learn how formation pressure are calculated using log and seismic data and industry standard algorithms Identify the critical data requirements for pore pressure prediction and evaluation Understand hazardous events of influxes and kicks during drilling operations Integrate subsurface data & drilling events, control data quality, identify non-pore pressure related hole problems, and understand the behavior of data before making any prediction analysis Specially Designed for The course is designed for those who want a deeper understanding in practical formation pressure evaluation and its application to wellsite operations. Wellsite Geologists Operations Geologists Well Planning Geologists Drilling Engineers LWD Engineers Mud Loggers Prerequisite: This course will assume that participants have at least a basic knowledge of wellsite geology practices and rig activities Supported by

2 Course Overview This course will provide a better understanding of pressure characteristics found in the subsurface. Delegates will be able to define 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 formation pressures.
