Abstract

<p>We analyzed tracer tests in the Ogiri geothermal field, which was conducted in 2008 and 2011, respectively. The test results were analyzed with the multi-flowpath model, then interpreted together with hydrological features of the field determined from geological settings and geophysical surveys. The results indicate the presence of two flow path for reinjected water flowing to the production zone in the Ginyu fault. A part of the reinjected water flows into the main production zone of the Ginyu fault directly through this fault from the west. The water also flows the Ogiri deep faults zone located to the south of the Ginyu fault, then flows into the Ginyu fault from the east which takes longer time to reach the production zone.</p>
