Abstract

The Pasema Air Keruh geothermal area situated within the Empat Lawang District,Sumatera Selatan Province. Magnetic, gradient temperature and geochemistry surviesconducted within that area, in 9 June 2012. The magnetic and the gradient temperaturewere not analysed zet. The geochemical analysis using the geothermometer andgeoindikator, doe to determine the reservoir characteristic and temperature. The firstgeothermal exploration activities in Empat Lawang District Sumatera Selatan Provincewere carried out in the Penantian hot spring field Air Keruh Sub District and Airklinsarhot spring field Ulu Musi Sub District. The discharge test measurements show that chemical composition of the reservoir water was analyzed by standard methods and subsequently classified using Cl-SO4, HCO3 triangular diagram. A Na-K-Mg triangular diagram was used to classify waters according to the state of equilibrium at given temperatures. The geothermal waters are of chloride water type and from a relatively old hydrothermal system. Thermal fluid is in equilibrium with reservoir rocks. The chemical geothermometers were used to predict subsurface temperature. The calculated temperatures using Na-K geothermometers and Na-K-Mg geoindikcator is more than 300oC. However, compare with measured temperature furthere.
