[Pertamina Geothermal Energy, Indonesia]

Kamojang geothermal field is the geothermal field with vapour dominated system, located in West Java, Indonesia with the generation of 235 MW from 5 (five) unit of power plants. The Kamojang geothermal field has been operating for 35 years. To understand better reservoir conditions, several geosciences survey were carried out, especially geophysical surveys. From the early phase of exploration around the 1970s to the exploitation and development phase, several geophysical surveys was conducted, such as DC resisitivity, Geo-Magnetic, CSAMT, Gravity, MT, MEQ, Sonic and resistivity logging. The new information obtained from geophysical surveys, such as MT, Gravity and microseismic is integrated with drilling data such as drilling cuting, coring, P & T survey analysis, production log, which aims to update the geophysical model and reservoir characterization.
