Abstract:

Numerical simulation is very useful in utilizing large scale geothermal energy, predicting reservoir response and optimizing exploitation procedure. Here we describe the OpenGeoSys (OGS) software used to simulate the complex processes in geoscience and hydrological applications, focusing on its application in geothermal energy utilization. OGS is based on an object-oriented finite element method concept and can deal with numerical simulation of thermo-hydro-mechanical-chemical processes in porous media. Case studies related to shallow geothermal energy (temperature and pressure prediction), hydrothermal energy (optimization on the distance between production well and reinjection well, scaling) and hot dry rock (hydraulic fracturing, permeability evolution) are shown with the purpose to help managing geothermal energy utilization.

Key words: OGS, multi-fields coupling, geothermal energy, numerical simulation
