What is Geomechanics ? Learn the fundamentals of geomechanics and latest technology in unconventional reservoir simulation available in GEM and STARS. Discuss key geomechanical topics from simple dilation/compaction table input to complex finite element strain/stress approaches. Several case studies and practical exercises will showcase single well to full field examples of geomechanical simulation in CMG’s simulators.

The information and techniques provided in this course will enable engineers to build a complex reservoir simulation dataset and analyze simulation run results using geomechanical features in GEM and STARS.
