The purpose of the studies are to develop the prospect area in order to support the Indonesian Government Policy to utilize the clean, environmentally and sustainable energy along with to reduce the use of fossil energy as an electrical power plant in the future. Geoscientific studies ( geology-geochemistry and geophysics ) in the Gunung Endut geothermal field is to delineate the geothermal potency of the area. The results of the study indicates that the hot water surface temperatures vary from 53oC to 88oC, with neutral pH. Based on the surface temperatutre data and referring to SiO2 and NaK geothermometry equation, therefore, the calculate of sub surface temperature is 162oC dan 180oC and can be classified as an intermediate enthalpy. The prospect area is about 4.5 km2 , with the possible resources are 60 Mwe.. The heat source of the geothermal system in the area is considered to be associated to volcano-tectonic activities. |
