Journal Article: Finite-Element Simulation Of Hot-Water-Type Geothermal Reservoirs
AbstractA fully coupled finite-element model is presented to simulate geothermal reservoirs in terms of the unknown variables of displacement, pore pressure and temperature using an elasto-plastic stress-strain relationship. The mathematical model combines the simultaneous mechanisms of subsidence, mass flow and heat flow through porous media by utilizing the equilibrium, fluid flow and energy flow equations. The governing partial differential equations are based upon constant physical parameters (except fluid density) and formulated for hot-water-type geothermal reservoirs. A simultaneous solution algorithm is applied to the modelling equations yielding transient and spatial distributions of the unknown variables. Application of the simulator to actual field conditions is performed by simulating the production history of a well located in the Denizli-KIzIldere geothermal field in Turkey. The results show an excellent agreement between the computed and the observed values of temperature and pore pressure variations throughout the reservoir.
