| Abstract | Numerical simulations of hypothetical enhanced geothermal systems (EGS) have been carried out in order to be able to understand what to expect from them in terms of power production. Since the quantity of unconventional geothermal resources in the world is larger than that of conventional resource it is a topic worthy of study. In this study simulations were carried out with different shapes for the cloud of fractures, with different numbers of production wells (1 to 4) and various injection rates (5 to 30 kg/s). The best set of parameters was found to be a configuration of 1 injection well in the centre of the cloud surrounded by 4 production wells located above the injector. This configuration produced a power output of 1.1 MWe. |
