| Abstract | The Ogiri geothermal system is characterized with the presence of steam-water two-phase zone and the fractured zone along Ginyu Fault which is the main target. For representing these characters, a numerical reservoir model has been developed. In the present study, we applied the MINC method to the grid blocks corresponding to the production zone of numerical model and carried out the history matching simulation with the model by using the code TOUGH2 (Pruess et al, 1999). |
