Course Details

Objective

This course covers the necessary fundamentals of reservoir geomechanics in a 3D environment; the origin of stresses in the subsurface and how in situ stresses could be understood using wellbore data, seismic and geological interpretations.

Methodology

A highly interactive combination of lectures and discussion sessions will be managed to maximize the amount and quality of information and knowledge transfer. The sessions will start by raising the most relevant questions, and motivate everybody find the right answers. You will also be encouraged to raise your own questions and to share in the development of the right answers using your own analysis and experiences. Tests of multiple-choice type will be made available on daily basis to examine the effectiveness of delivering the course.
All presentations are made in excellent colorful power point. Very useful Course Materials will be given.
