Abstract

Many of the oil and gas installations in the Indonesian Sea are reaching the end of their economic production life. Typically, oil and gas fields have an economic life of 20 to 40 years and a decommissioning program will be required and predicted to peak during the period 2010-2020. Some of them are located in shallow water such as those around Pulau Seribu, Java Sea, and South China Sea; some others are in deeper water such those at Makasar Straits and Moluccas Sea. Many different opinions exist on the benefits and problems of a partial platform removal or a complete removal. For some reasons platforms would be a good fishing spot. On the other hands, an unseen hazard could be left behind by the platforms. Even a complete removal of the platforms is conducted but without proper clearing of the ocean floor, the unused platforms still can cause hazards. For the management of the seas outside the territorial waters, worldwide nations have historically entered into international agreements and conventions. These agreements and conventions that have been entered into under the umbrella of the United Nations are Geneva Convention, the United Nations Convention on the Law of the Sea (UNCLOS) and the International Maritime Organization (IMO) Guidelines. Nationally, there is little information concerning with the decommissioning project. This paper is intended to highlight options for decommissioning of offshore platforms, its environmental impacts, and regulations that could be referred to following the decommissioning proposal. The technological aspects of the structural decommissioning of platforms are beyond the scope of this paper.

Abstract

Tolo Bay is located between East Arm and Southeast Arm Sulawesi, reaching a water depth of up to 3500 meters below sea level. Regionally, this block is situated within Banggai Basin where some gas and oil fi elds are already in production. The closest fi eld is Tiaka Oil Field located about 125 kilometers northwest of the study area. A geo-science review has been conducted to clarify the potential existence of hydrocarbon in this block. Based on previous reports, papers, and subsurface data from the Directorate General of Oil and Gas, the study area is located within the collision area between Banggai-Sula Microcontinent and Sulawesi. This collision occurred during Late Creataceous and Middle Miocene periods. During drifting phase a sedimentation process occurred at the front of the Banggai-Sula Microcontinent. This sediment is potentially source rock and reservoir rock. Meanwhile, during the drifting phase the study area is interpreted as located at the southern part of Banggai-Sula Microcontinent. This different tectonic setting will impact on the type of sedimentary rock, hence source rock and reservoir rock occurrence in the study area is still unclear. As source rock and reservoir rock within the study area are unclear, hydrocarbon explorations will be very risky. In order to reduce exploration risk, it is proposed to conduct geological and geophysical studies using the latest seismic data that was surveyed by PT. TGS – NOPEC and PT. ECI – PGS.

Abstract

Oil and gas are important commodities in Indonesia and remain the main source for energy in various sectors. Therefore, the government aim to produce 1 million barrels of oil per day (BOPD) by 2030. To achieve this goal, exploration work is needed to discover new reserves and maintain production in existing fields. This study reviews the experience of oil and gas exploration in Indonesia using remote sensing data and the potential of using remote sensing data for oil and gas exploration through surface anomalies. Surface anomalies are changes or deviations that occur on the surface as the result of the presence of oil and gas underneath. These anomalies included vegetation growing stunted, yellowing or dying, changes in the quantity and composition of clay minerals, iron oxide, increased concentrations of hydrocarbons, helium, radon, carbon dioxide, microbes, and the presence of paraffin dirt formation, as well as geomorphological changes. This study aims to assess and explain the capabilities of remote sensing data in Indonesia for oil and gas exploration. The results show that remote sensing can be used for the initial exploration of oil and gas by delineating areas of potential oil and gas traps based on topographical anomalies and geological mapping integrated with gravity data and increasing confidence in the presence of oil and gas in the subsurface based on surface anomalies. These results are expected that the usefulness of remote sensing can be used to support oil and gas exploration in Indonesia and can be recognized and used for oil and gas activities by utilizing existing methods and discovering methods for data processing and their applications.

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

Central Sumatra Basin is one of the most prolifi c hydrocarbon basins in Indonesia and has proved itself as being the largest contributor to Indonesia’s national crude oil production. Heavy oil fi elds in the basin, such Duri fi eld as the largest one, plays a very important role in making up the basin’s whole oil production output. In general, the Central Sumatra Basin is also acknowledged for its heavy oil potential. Accordingly, a study under the auspices of the Ministry of Energy and Mineral Resources (MEMR) of the Republic of Indonesia is carried out to re-visit the potential. The study establishes and implements an integrated approach formed by a combined macro and micro analyses. In the macro analysis, a combined evaluations of regional geology, geophysics, geochemistry, remote sensing/geographic information system ( GIS), regional geothermal study, and fi eld survey/ microbiology is performed to identify geological positions of the heavy oil potential. In the micro analysis, on the other hand, qualitative and quantitative well-log analyses supported by well-test and laboratory measurement data on the identifi ed geological positions are carried out with an aim of identifying heavy oil bearing reservoirs/traps under three categories of certainty. The main result of the study is identifi cation of 51 fi elds/structures - producing and non-producing – that bears heavy oil within the three categories. Findings of the study can certainly be used as a prerequisite for more intensive and expansive studies to meet the need for a more solid conclusion regarding the heavy oil potential of the Central Sumatra Basin

Abstract

Heavy oil which is classifi ed as non conventional oil is the target of exploration in the world. In Indonesia, the potential for heavy oil exploration is quite large, especially in the Central Sumatra basin. This study aims to map the location of potential heavy oil based on remote sensing data and regional gravity data supported by a geographic information system. Landsat 8 OLI satellite data is processed to produce 567 (RGB) color composite images, then further processing is carried out with DEM data to produce fusion images; mapping the vegetation index, clay mineral index, iron oxide index, surface temperature. The gravity data is used for mapping subsurface geological structures. Overlay analysis is carried out on the results of remote sensing data processing and interpretation of surface and subsurface geology. Based on the analysis, it shows that heavy oil fi elds are generally found on the surface and subsurface structures which are relatively identical and located on the edge of the basement high. Based on this analysis, the locations that have the potential for heavy oil and gas traps are on the northeast edge, Dalu-dalu High, the edge of Kampar High, the west edge of Kuantan High, the southwest edge of the Beruk High, the southwest edge of the Sembilan High.
