| Abstract | A three-year research project was conducted in FY2010- 2012 to develop an integrated geothermal reservoir operation system for adequately controlled utilization and to apply the system to model fields. The purpose of this study is to prove that geothermal exploitations can be performed without interference to nearby hot springs. The project consists of three parts: Geothermal system modeling, Development of monitoring techniques, and Estimation of reservoir change by numerical simulation, all including nearby hot spring aquifers. The integrated geothermal reservoir operation system was applied to two model fields, the Hachijojima and the Minami-Izu geothermal fields. As results, the relation between geothermal reservoir and hot spring aquifer(s) in the Minami-Izu field was identified as “identical system” or “water supply from deep reservoir” in which a geothermal development may affect on hot springs, while that in the Hachijojima field was identified as “identical systems” in which a develop may not affect. A proto-type system support software, which helps “type analysis of hot spring and geothermal relation” and “time series analysis of hot spring monitoring data” was also developed. Since the software needs some improvements for practical use, improvement will be done in a separate project. |
