The natural and artificial fractures in a rock influence both its mechanical and hydraulic characteristics. To overcome the challenges in conventional methods of the coupled multi-physical simulation of fractured porous media, an advanced mesh generation method and some multi-physical models based on discrete fracture network were developed. Verification sensitivity analysis, and convergence for these models were accomplished. This work investigated and evaluated the coupled thermo hydro-mechanical process in enhanced geothermal systems using either water or supercritical C02 as a working fluid.
