COURSE CANCELLED - Cont. Ed: Accelerated Learning Tutorial: Geomechanics for Unconventional Reservoir Fracturing; Basics to Field Application

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 “Geomechanics for Unconventional Reservoir Fracturing; Basics to Field Application” one day course with focus on unconventional reservoir completions is offered.
