Two decades of hydrocarbon exploration activity in Indonesia
During the past two decades, hydrocarbon exploration activity within Indonesia has been based on the Indonesian Energy Policy, aims of which include intensifying and expanding hydrocarbon exploration programs. Expansion into the offshore regions of the nation has resulted in the discovery of petroliferous basins. The first offshore oil production came on stream in 1971. Since then, significant achievements have been made in developing these resources. Intensified onshore exploration has resulted in additional oil fields being discovered in these more mature areas. Among the significant gas fields discovered during the past 20 years, Arun and Badak both supply major LNG projects. Oil fields have been found in the onshore areas of Sumatra, Kalimantan, Java, and Irian Jaya, and in the offshore areas around West Java, Madura, Natuna, and East Kalimantan. The exploration drilling success during this time has been approximately 32%. In addition, the ratio of oil field development to these discoveries is about 54%. For technical and economic reasons, not all discoveries can be developed into oil fields. Recently, Pertamina's Research and Development Division organized the study of data contributed by Pertamina exploration, foreign contractors, and science institutes. This study reveals that 60 basins are spread throughout the onshore and offshore areas of the nation. Using PAUS (plan and analysis of uncertainty situation), a Monte Carolo simulation program, the hydrocarbon potential of each basin has been estimated. These estimates will be continually revised as more data are made available to the study, as the geology of Indonesia is better understood in terms of plate tectonic theory, and as computing techniques improve.
