| Abstract | A three dimensional numerical reservoir model of the Takigami geothermal field was developed by inverse analysis method. The model was calibrated by using iTOUGH2 simulator that improves a set of reservoir parameters simultaneously. Natural state, production and reinjection histories were sequentially simulated. Initial temperatures from 21 wells were matched with a numerical model in the natural state simulation process and discharged enthalpies from five production wells about 11 years in the exploitation history. A good agreement was obtained for initial temperature profiles and discharged enthalpies of production wells with the model. |
