The utilization of geothermal energy for the direct use in Mengeruda, Flores Island, Indonesia

Abstract

At least eight hot springs, and weakly altered rocks occur along the NE-SW trending fault as geothermal surface manifestations. Judging from the results from these surveys, it is considered that the geothermal system is probably an out-flow type. The constructed models of the Gou and Mengeruda geothermal areas also show that geothermal fluids seem to be an out-flow system. The purpose of this paper is to evaluate whether the Mengeruda prospect area is adequate for direct or indirect use in geothermal utilization. Using the results of geological, geochemical and geophysical surveys, Mengeruda is recommended for a direct use of geothermal energy. The direct use geothermal energy is drying agroindustrial products, hydrating and tourism.
