This research aims to provide a good model which produces reasonably accurate predictions of reservoir performance in the future. In addition to that, the model is intended to clarify the geological structures, distribution of physical properties, and geothermal fluid flow pattern in Patuha geothermal field. To simulate using TOUGH2, the model was constructed by integrating geologic, geophysical, geochemical, and deep downhole pressure and temperature data. By varying its permeability, heat and recharge magnitude and locations, and geometry of the geologic feature, the model has been calibrated and showing the reasonable result which was obtained by the small difference in pressure and temperature between the simulations and observed data. The model therefore well defines the Patuha geothermal system around the Bandung Basin. Furthermore, this model can be used to simulate future production scenarios to evaluate the sustainability of the reservoir.
