Geomechanics in GEM and STARS
Who should attend
This two-day course is designed for engineers, geologists, or other technical personnel who would like to learn the geomechanical features in CMG's GEM and STARS simulators. Basic knowledge of CMG simulator functions are required to learn the geomechanical features and applications.
About the course
This course will introduce the Geomechanical concepts from simple dilation/compaction table input to complex finite element strain/stress approaches and subsidence/thermally induced fracturing during water flooding. Attendees should be familiar with basic simulation work and have some practical experience in black oil, compositional, or thermal simulation. The stress-related phenomenon will be discussed including rock deformation and subsidence. Caprock integrity and modelling of cap rock failures will be discussed and illustrated. Simple elasto-plastic yield to more complex cap models will be explained and demonstrated. Single well to full field examples of geomechanics simulation in GEM and STARS will be illustrated. Analysis of the simulation runs will be performed to have a better understanding of these Geomechanical features. This course will provide participant enough information and techniques to build a complex reservoir simulation dataset with geomechanical effects and explore the more complex functions of GEM and STARS simulators.
