Abstract
A quantitative reservoir model of present state has been developed through a natural-state simulation, in order to evaluate the geothermal potential of Oguni field in Japan. A series of calculation was carried out to forecast reservoir response to fluid production and injection using the natural-state model. The MINC type fracture model was introduced to this exploitation calculations, with equivalent steady properties. The thermal influence of low temperature reinjected water on the proposed production area was appraised. From this study, it was concluded that the projected productionheinjection scheme is appropriate for the future stable operation of power station.
