This course covers the necessary fundamentals of geomechanics for wellbore applications; the origin of stresses in the subsurface and how in situ stresses can be understood from wellbore data; mechanical properties such as rock strength, and the origins of pore pressure and how it is measured and estimated. The course then proceeds to show how these data are applied through the Mechanical Earth Model to critical problems in exploration and field development. There are detailed case studies on wellbore stability sand production and hydraulic fracturing. The course also includes an introduction to reservoir geomechanics, showing the geomechanical influence of pressure changes in the reservoir.
At the end of the course attendees will be able to:
- Use routinely collected and specialized data to make basic geomechanical calculations for wellbore stability, sand production and hydraulic fracturing
- Select and design data acquisition for geomechanical studies
- Interpret image data to identify basic geomechanical behaviour
This course is also available as a 3 day class without classroom exercises
