Claim:
1. A method of performing a fracture operation at a wellsite, the wellsite positioned about a subterranean formation having a wellbore therethrough and a fracture network therein, the fracture network comprising natural fractures, the wellsite stimulated by injection of an injection fluid with proppant into the fracture network, the method comprising: generating wellsite data comprising natural fracture parameters of the natural fractures and obtaining measurements of microseismic events of the subterranean formation; modeling hydraulic fractures of the fracture network based on the wellsite data and defining a hydraulic fracture geometry of the hydraulic fractures; generating a stress field of the hydraulic fractures using a geomechanical model based on the wellsite data; determining shear failure parameters comprising a failure envelope and a stress state about the fracture network; determining a location of shear failure of the fracture network from the failure envelope and the stress state; and calibrating the hydraulic fracture geometry by comparing the modeled hydraulic fractures and the locations of shear failure against the measured microseismic events.
