Abstract

Sulawesi is one of the area in Eastern Indonesia that still has frontier area. South Sulawesi has several basins which formed as a result of tectonic activity that caused a geological condition complexity. The complexity of the regional geology is one of the interest of this research. The presence of gas seep within research area ensure that there is a potential petroleum system underneath the surface of the research area which is Padamarang sub-Basin, Bone Basin, South of Sulawesi. New insights into Bone Gulf is based on surface geochemical exploration that came up with 26 core sea sediments samples using piston core acquisition that has been analyzed with Gas Chromatography in sediment extract.  This study aims to identify the geochemical characteristics of migrated hydrocarbon. These geochemistry characteristics referred to depositional environment and maturity determination that are analyzed using non biomarker parameters including CPI and OEP, and cross plot between CPI and Pr/Phy. According to the CPI value has shown the number from 0.169 to 1.27 with the majority of the values is 0.4. While OEP value has shown the number from 0.312 to 1.5 with the majority of the values is 0.75.  Thus, according to the majority value of CPI and OEP, we could determine that it was thermally immatured.Keywords: Biomarker, Core, Geochemical, Non Biomarker, Padamarang

Abstract

Bone Gulf in South Sulawesi is an area with the possibility of potential hydrocarbon deposits. This research was conducted to examine the characteristics of Hydrocarbons gotten from Core Extractionfrom underwater geochemistry survey in the area of study by geochemical analysis methods and compared with known geological data. Geochemical analysis was carried out on 27 seabed-core samples taken from the area around the Kabaena sub-basin to determine the maturity level and depositional environment and the source of organic material from the Hydrocarbon producing Source Rock. Determination of the maturity level and depositional environment is based on CPI and OEP value, as well as N-Alkane and Isoprenoids which obtained from Gas Chromatography (GC). Geochemical analysis for the maturity level of all the samples showed the maturity level of immature to mature. Geochemical analysis for depositional environments on all samples showed a tendency to be deposited in the transitional and the sources of organic material is Mixed Kerogen.Keywords:        Bone Gulf, Hydrocarbon, CPI and OEP, N-Alkane, Geochemistry Analysis, Source RockABSTRACTBone Gulf in South Sulawesi is an area with the possibility of potential hydrocarbon deposits.
