Geothermal Energy Potential of Arjuno and Welirang Volcanoes Area, East Java, Indonesia

Untung Sumotarto

Abstract


Indonesia is a country having a high geothermal energy potential. The geothermal energy in Java island, as a volcanic row island, has been explored and produced. One of the areas that have not been produced is volcanic area around Arjuno and Welirang volcanoes located in East Java. Geochemical survey has been performed to explore a more detailed objective in exploring the potential resource of geothermal energy of this area. Chemical and isotopic analises show the maturity level of waters taken from water springs in the area. The immature water from the water springs is interpreted coming mostly from meteoric water which flows quite fast forming water springs around the area. The geothermal reservoir thermometer has been predicted to arive 300 to 350 degrees C. Using available data and information, geohydrothermal of the area has been modeled. Further, the energy potential has been calculated to achieve about 200 MWe.
