Indonesia Geology Potential Study
Indonesia according to Ministry of Energy, estimated has 60 sedimentary basin as reservoirs for oil and gas, three biggest are Kutai, Tarakan and South Sumatera Basin. So far only 38 basin that explored. The study of geological potential in Indonesia is challenging, since there are not so many study conducted and the nature of research that require high cost investment. Some of the study as follows:
Study by Iskandar et al (2013) on Ranking of Indonesia Sedimentary Basin and Storage Capacity Estimates for CO2 Geological Storage, rank the basin and its estimation for CO2 geological storage.
A study by Doust and Noble (2007) on Petroleum systems of Indonesia, stated that “Indonesian petroliferous basins share a number of important characteristics: most are Tertiary in age and pass through early Tertiary synrift to late Tertiary postrift stages of geological development. They are filled with non-marine to marine sediments subject to rapid environmentally-controlled facies variations and receive charge almost exclusively from terrestrial and/or lacustrine source material”
Hochstein and Sudarman (2008) on History of geothermal exploration in Indonesia from 1970 to 2000 stated that “In summary, geothermal exploration in Indonesia from 1970 until 2000 can be seen as a sequence of successful and less successful developments undertaken partly by the public sector (Indonesian Government agencies) and partly by private industry”
Stevens and Sani (2002) on Coalbed Methane Potential of Indonesia: Preliminary Evaluation of a New Natural Gas Source stated that “CBM development costs will likely be higher in Indonesia than in the U.S., at least initially, and fiscal incentives may be required to jump-start this new gas supply source”
van Leeuwen (1994) on 25 years of mineral exploration and discovery in Indonesia stated that “The unprecedented high level of mineral exploration activity over the past 25 years can be attributed to Indonesia’s mineral prospectivity and favourable investment climate. Given a continued competitive commercial environment and sustained commodity prices, the next 25 years should see further strong development of the country’s mineral resources.”
