Cont. Ed: Accelerated Learning Tutorial: Introduction to Petroleum Geomechanics (with focus on Unconventional Completions)

There are number of challenges in unconventional reservoir completions that will benefit from geomechanical considerations. Examples include complex hydraulic fracture development in naturally fractured reservoir, altered in situ stresses due to production, and reservoir re-stimulation, and coupled thermo-poro-mechanics processes.  Recognizing the critical need to understand fundamental mechanisms involved in unconventional reservoir development, the “Introduction to Petroleum Geomechanics” one day course with focus on unconventional reservoir completions is offered.
