Available geothermal energy extractable by conventional techniques is in dry and comparatively impermeable
rocks. Enhanced Geothermal System (EGS) technologies enhance geothermal resources in the hot dry rock (HDR) through fracture
operations, usually through hydro-shearing. Large scale deployment of geothermal power production requires the demonstration of
successful EGS projects extracting heat from reservoirs constituting a variety of geological conditions. In this part, numerical
models are very important to show how geothermal power plant operations can be less risky and safer. Owing the fact that, some
major challenges in these operations are interaction between shear and tensile fractures with natural faults. These interactions can
be seen in two different cases, either these faults are badly oriented or these faults are fill in pore fluids or gases which are mainly
high pressure. Fluids and gases are important on account for because of the fact that these pore fluids can over whelmed the
injection pressure and cause well blow out. Furthermore, to prevent these operational hazards, we use field data and analysis in
combination with experimental tests and numerical/analytical models with finite element method software such as COMSOL
Multiphysics. Further work will be required for improving enhanced geothermal production by optimizing hydro-shearing
practices
