Course Description
This course covers the necessary fundamentals of geomechanics for wellbore applications. First of all, the origin of stresses in the subsurface and how in situ stresses can be understood from wellbore data. the course also discusses mechanical properties such as rock strength, the Mechanical Earth Model, and the origins of pore pressure and how it is measured and estimated. It proceeds then 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.
