Pore Pressure, Fracture Pressure and Wellbore Stability Management Course

Course Level: Skill / Advanced

Formation pressure prediction and evaluation is a safety critical task. This course provides you with the fundamental skills required for pre-well prediction and subsequent real-time evaluation of subsurface pressures (overburden, fracture and pore pressures) using a variety of direct and indirect methods. It will also introduce you to the basics of wellbore stability analysis and describe how recognition of the pore pressure generation method is so important for prediction and evaluation.

DESIGNED FOR YOU, IF YOU ARE…
• A geologist, geophysicist or engineer requiring a fundamental understanding of the principles and applications of pore and fracture pressure in addition to wellbore stability
• A wellsite or operations geologist wishing to advance your knowledge to an expert level
The course assumes some basic knowledge of operations or wellsite geology and good awareness of drilling operations.

HOW WE BUILD YOUR CONFIDENCE
You will be taken along a path which gradually introduces each topic and uses many exercises and case studies to illustrate the points made. The manual provides a good future reference for what has been taught on the course.

THE BENEFITS FROM ATTENDING
By the end of the course you will feel confident in your understanding of:

• The essential concepts of subsurface pressures and stresses and their interrelationships
• Pore fracture and overburden pressures and how to calculate them
• The origins of geopressures and how pressure regimes develop through time
• How geopressures affect the distribution and migration of hydrocarbons
• The centroid principle and pressure transfer
• How formation pressures will affect well planning and risk evaluation
• Subsurface stresses and associated wellbore instability
• Pore pressure prediction and real-time evaluation using trend analysis
• Fracture gradient evaluation and interpretation of leak-off tests and FITs
• How to distinguish causes of wellbore instability
• How hole conditions, shale caving and gas can be used in evaluations

INSTRUCTOR:-
Tim Herrett holds a B.Sc. (honours) in Geology from Portsmouth University, UK and is a chartered geologist with the Geological Society of London. Starting in the industry as a mudlogger in 1978 he subsequently worked as a pore pressure engineer, wellsite geologist and then operations/project geologist. He is considered a subject matter expert in these roles as well as formation pressure evaluation and HTHP wells having worked as a contractor for extended periods with ExxonMobil and BP as well as many other companies. He designed and developed software for wellsite and office use which are now commercially used in the industry. He was founder and technical director of Cambrian Consultants with responsibilities for training, computing and software products.
Tim is the author and presenter of well-received industry training courses worldwide. All his courses have been peer-reviewed and accredited by the Geological Society of London. Tim currently provides training courses for HOT, lectures part-time on two M.Sc. courses at the universities of Manchester and Derby and performs independent pressure studies for various oil companies. Over the last 6 years he has co-written and is lead facilitator/trainer on BP’s Accelerated Development Programme for Operations Geology.
The courses he presents are based on years of experience and practical knowledge which are used to enhance the learning experience. Tim was chairman of the convening committee for the Operations Geology Conference held in London in November 2016. He created, distributed and presented the results of a survey of operations geologists at this conference.
