| Abstract | Gonen geothermal system can be defined as low temperature fracture zone system that was formed on NE-SW oriented Yenice-Gonen fault, which was created by the North Anatolian Fault. The geothermal system seems to be locally delimited by smaller faults that were identified by geophysical surveys. Partial reinjection conducted in the field did not stop pressure decline and caused cooling in the geothermal reservoir. After quadrupling the capacity of the district heating system in 16 years of exploitation, a pressure drop of about 6 bars and a cooling of 10-15 o C were observed in the reservoir. In this study, by analyzing the geological, geophysical surveys and the available tests conducted, problems arisen from the existing reservoir management are stated, and solutions are proposed for improving utilization of the geothermal system on the way to sustainability. |
