Abstract

Although revenue from the oil and gas industry is no longer the main source of national income, it is still playing a strategic role. The oil and gas industry is known as a high-tech, a high-risk, and a high-capital industry, on which the country has limited capacity for regional development, especially of the resources in areas located along the national border. The main objective of this research is to closely identify the recent growth centre status of blocks and sedimentary basins located along the national border. The study relies on published reports, studies, and data such as bathymetry map, national geographic and jurisdiction map, and maps of existing oil and gas blocks. All data were managed under a geographic information system application in order to conduct comparative and qualitative analysis of those overlaying data. Some oil and gas blocks that are located near to neighboring countries, such as Singapore, Malaysia, Brunei, Vietnam, The Philippines, Papua New Guinea, East Timor, and Australia have been categorized based on these methods of scoring and ranking analysis to identify new economic centres of growth. Three categories are suggested: very important, important, and ordinary as new growth centres. The Natuna Sea blocks, Iwur, and Timor blocks are considered to be important.

Abstract

Buton island as a potential area for conventional oil and gas, as well as asphalt/bitumen has long been the target of evaluation aimed at exploiting this potential, although to date no economic exploitation has been implemented. In this study, the potential of Buton asphalt/bitumen with mineable and in situ (non-mineable) status was studied and evaluated. In this study, qualitative and quantitative analysis have been carried out from Landsat 8 and Shuttle Radar Topography Mission (SRTM) data with the aim of identifying the presence of active faults and gravity due to orogenic processes. The lineament density pattern shows a general direction of NE-SW to NNW-SSE. The lineament process between satellite image data and gravity surveys helps efforts to identify the distribution of asphalt on Buton Island. Through combining distribution patterns of the Sampolakosa, Tondo, and Winto Formations, contain asphalt/bitumen, the study produces distribution of asphalt/bitumen accumulation in the region, both in surface/mineable and in situ categories. The 'best estimate' reserves obtained are 786.6 million barrels and 46 million barrels, respectively for asphalt/bitumen surface/mineable reserves and in situ/non-mineable reserves. It is hoped that this information regarding the potential/reserves of asphalt/bitumen on Buton Island may support efforts to exploit it

Abstract

Oil production from the extraction of Buton Asphalt (Asbuton) becomes an attractive bitumen to study considering that the use of Asbuton is currently still relatively limited for asphalt needs with absorption of only 0.9% of national asphalt needs, of course this is a contradiction considering Asbuton deposits reach 667 million tons. Another factor is the high price of crude oil encouraging the use of bitumen as an alternative to crude oil, especially heavy crude oil. Bitumen reserves contained in Asbuton are capable of meeting oil refinery needs of 50,000 BOPD or the equivalent of 4.3% of domestic refinery capacity for a period of 20 years. There are two options for Bitumen production from Asbuton, namely all production comes from open pit mining or a combination of production from open pit mining (40%) and in situ extraction (60%). The techno-economic analysis was prepared with the assumption that the Asbuton production area is part of the Oil and Gas Working Area with a Cost Recovery Production Sharing Contract (PSC) scheme. The development of Bitumen production from Asbuton provides feasible economic indicators with NPV = $ 973 million and IRR = 15.2%. During the contract period, the government received revenue of $ 12.0 billion and the contractor $ 14.6 billion. This economic feasibility study is expected to enrich further our understanding over Buton asphalt utilization in support of crude oil production in the future

Abstract

Since 1980 the nuniber of Indonesian Sedimentary Basin which is officially announcedby the government are 60 basins, but informally the variation in the range of less than 60up to around 66 basins. Based on stratigraphic and tectonics conditions of some areasthere are overlapping layers between Tertiary Sedimentary and Pre Tertiary Basin. In general the definition of a sedimentary basin is a region, part of the earth's crustwhere sedimentary strata have been deposited in a relatively much greater thickness thanits surrounding area. The nomenclature for basin is referred more to basinal areas. Basedon sedimentary basin classification there are: type of plate where basin exists, basin posi-tion in the plate margin, type of plate interaction, tinie development of basin and basins fiilwith respect to tectonic and shape of the basin. The updating classification using new technology and knowledge of the basin, canalso update previous knowledge because of the limitation of the data and the lack of newconcept when the report was published. 63 Tertiary Sedimentary Basins (16 producing basin of oil and gas, 8 drilled basin withdiscovery, 15 drilled basin with has no discovery yet and 24 basin which has not beendrilled yet) could be used as a basic data for development of Science and technology, tosupport government policy and investor, to improve and accelerate oil and gas explorationand production in Indonesia.

Abstract

Industrial minerals are useful as drilling materials support such as; limestone(MgCaCOJ for filler, bentonite and barite for drilling mud and quart: sand for proppingagent. Until ncrw the benefit of thern has not been optimized because it is only as buildingmaterial, and still the mining -which cause environmental damage. Concerning the environmental care and to support the movement of using nationalproducts of oil and gas activities need innovations and creativities in taking the benefit ofthose minerals. The alternative that has been chosen such as the effort of the balancingbetween the national products and big investment in oil and gas. To rnake condition of bentonite as drilling mud was needed activation and change itto sodium bentonite to improve those mineral suspension by polymer added. Meanwhileindustrial development of silica sand as gravel packing and propping agent, have beenbetter within mining activity in Bangka Area. Average quality of silica sand consist Si O,up of 90 % to satisfy the requirements, but still was quality improved. In few regions inIndonesia overall industrial mineral can be used to support oil and gas activities. Key words: environmental, industrial minerals, upstream oil and gas activities.
