Pre-Feasibility Study
Under the Decrees of the Minister of Energy and Mineral Resource (ESDM) issued in 2008, PT. Supreme Energy was assigned to conduct pre-feasibility studies in Liki Pinangawan Muaralaboh and Gunung Rajabasa geothermal prospects. These assignments were completed in 2009 within the time specified in the decrees. The studies have successfully estimated the possible reserves and established the concession area for each of the prospects based on the conceptual models constructed by the integration of geological, geophysical, geochemical data and prior wells. Geotechnical data was added in order to identify any constraints or hazards for development of the field. The earth science data acquired during the pre-feasibility studies were used to estimate resource size of the prospects.

Current Status
Following the tender award of the Muara Laboh and Rajabasa concessions to the Supreme Energy Consortium in early 2010, a mining area license (IUP or Ijin Usaha Pertambangan) was issued to each of the project companies.

PT Supreme Energy Muara Laboh has started the exploration program and it has recently completed the Micro Earth Quake (MEQ) surveys. Airborne topographic survey and civil engineering studies are ongoing for Muara Laboh. Similar activities are also planned and scheduled to be conducted in the near future for Rajabasa. Exploration drilling is expected to begin first in Muara Laboh in early 2012 and subsequently followed by drilling in Rajabasa.
