During hydraulic stimulation in unconventional resources such as shale gas or geothermal, newly forming and preexisting fractures interact to generate complex fracture networks. A model was developed that couples fluid flow and stresses induced by fracture deformation in large, complex discrete fracture networks. Modeling these processes with discrete fracture networks is useful because the stresses induced by fracture propagation and deformation are spatially heterogeneous and depend on the relative locations and orientations of neighboring fractures. The model also has the capability to describe friction evolution on fractures, allowing it to directly describe the processes giving rise to induced seismicity. In this talk, details of the model will be summarized and applications to practical problems will be given.
