Develop and implement an integrated methodology for building geomechanical models of tight gas systems (shale) that include knowledge of important characteristics of the native fracture network in the original undisturbed system, investigate through theoretical analysis, numerical simulation, laboratory studies and field experiments the interrelation between the geomechanical and geophysical behavior of such systems in the course of well completion and stimulation, and develop models of the coupled flow, geomechanical geophysical and geochemical behavior of fractured tight gas systems from the earliest stages of well stimulation to long-term production, and use the results of the field test to validate them.
