The utilization of geothermal energy for electricity in Indonesia has grown rapidly. It is characterized by the acceleration of electrification program phase II, where geothermal energy contributes a large part of it. With high attention from various parties involved in it, there are several obstacles in geothermal energy utilization. One of the obstacle is geothermal electric pricing should be set at the level of certainty of geothermal energy resources is still low. <br /> <br /> <br /> Mining Working Area (WKP) which will be tendered generally classified as possible reserve, or an area with a lower potential classification level. Classification of potential assessment methods, according to the national standardization in Indonesia (SNI), is conducted by using volumetric method. The volumetric method basically has an internal weakness, namely the use of recovery factor assumptions that are independent against reservoir characteristic parameters. <br /> <br /> <br /> This thesis is about the utilization of volumetric method improvement which the recovery factor will be dependent on the characteristics of reservoir parameters. Improvement of volumetric method is done by the combination of probabilistic, volumetric and numerical simulation. The improvement method of potential assessment is expected to provide a better potential assessment that can lead to a proper electricity pricing.
