Pre-Feasibility Study
PT Supreme Energy has completed the pre-feasibility study of the Rantau Dedap geothermal prospect in March 2009 as assigned by the Minister of Energy and Mineral Resources. The study successfully estimated the possible reserves based on the conceptual model 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. Based on the study findings, the Rantau Dedap Concession was established and the open tender was conducted by the Government.

Project Updates
The concession for the Rantau Dedap has been awarded to the Supreme Energy – GDF Suez Consortium in early December 2010 and the Mining Area License was granted to the project company PT Supreme Energy Rantau Dedap. The preparation work to support the exploration program is ongoing. Detailed topographic survey, micro-earthquake survey, civil engineering works and associated permitting and land acquisition activities will start in July 2011.
