| Abstract | : | The first geothermal exploration activities in Empat Lawang District, Soth Sumatera Province, Indonesia were carried out in the Airklinsar field, Ulub Musi Sub-District. The discharge test measurements show that wells Airklinsar spring produce predominantly from a single-phase, reservoir (liquid) with a temperature of 225oC and 223oC. The temperature analisys using silica and Na-Mg geotheermometers.The chemical composition of the reservoir water was analyzed by standard methods and subsequently classified using Cl-SO4, HCO3 and Cl-Li-B triangular diagrams. 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 type and from a relatively old hydrothermal system. Thermal fluid is in equilibrium with reservoir rocks. The chemical geothermome-ters were used to predict subsurface temperature. Silica geothermometers give temperature more close to measured temperature whereas cation geothermo-meters show significantly higher Silica geothermometers. |
