The other three simulations used a stochastically generated network of natural fractures and assumed that as hydraulic fractures propagated through the formation, they terminated when they intersected natural fractures. The termination process created...

... stimulation of a well. It is a “screening model” meaning point-by-point details of the natural fracture distribution, fluid leakoff, and failure prediction are not emphasized. By matching this to the microseismic cloud of shear failure, we obtain the injection permeability and porosity, which characterize...
