Abstract: A method of performing a fracture operation at a wellsite about a subterranean formation having a fracture network with natural fractures is provided. The wellsite is stimulated by injection of fluid into the fracture network. The method involves generating wellsite data including natural fracture parameters and obtaining measurements of microseismic events, 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, 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.

Abstract: A method of performing a fracture operation is provided at a wellsite. The wellsite is positioned about a subterranean formation having a wellbore therethrough and a complex fracture network therein. The complex fracture network includes natural fractures, and the wellsite stimulated by injection of an injection fluid with proppant into the complex fracture network. The method involves generating wellsite data comprising measurements of microseismic events of the subterranean formation, modeling a hydraulic fracture network and a discrete fracture network of the complex fracture network based on the wellsite data, and performing a seismic moment operation. The method involves determining an actual seismic moment density based on the wellsite data and a predicted seismic moment density based on shear and tensile components of the simulated hydraulic fracture network, and calibrating the discrete fracture network based on a comparison of the predicted moment density and the actual moment density.
