A two-dimensional numerical model is used to study the response of enhanced geothermal reservoirs to stimulation and production. In the model, the discrete fracture network is explicitly represented, and the solution is thermo-hydro-mechanically coupled. A series of metrics including shear- stimulated area, injectivity, produced water temperature and produced energy are evaluated for each case. Comparison of these metrics provides insight into the effect and range of importance of these parameters.
