Kajian Geokimia Molekuler Minyak Bumi Dari Ladang Minyak Bumi Bakau Dan Beruk (Blok Selat Panjang) Menggunakan Distribusi Biomarker (Gammaserana, Hopana, Dan Oleonana)
Petroleum is a natural enrgy source that requires a long time to form. Petroleum derived from source rocks requires hundreds of millions of years to from petroleum, but the use of petroleum in indonesia is increasing every year, while the amount of oil production in indonesia is decreasing in number of production each year. Therefore it is necessary to explore in the search for new and productive. Petroleum samples from Bakau an Beruk (Selat panjang block) are new oil wells that were discovered in 2017 and there no data on these oil wells, so needed analysis molecular geochemichal. Crude oil were fractionated using chromatographic columns into fractions. The analysis was carried out on the aromat fraction using gas chromatograpi mass spectroscopy (GC-MS) m/z 191. This study aimed to determine the level of maturity, origin of organic material, depositinal environment, hypersalin content, and correlation petroleum wells with using biomarker parameters such as hopana, gammaserana and oleonana. Based on the results of the study showed Bakau hopana (0,63) and Beruk (0,50), Bakau gammaserana (0,10) and Beruk (0,19), Bakau hopana (0,63) and Beruk (0,50), Bakau oils gammaserana (0,10) and Beruk oils (0,48), Bakau oils oleonana (1,72) and Beruk (1,040). Based on the analyses shows that oil from Bakau and Beruk originated from organic plant material from high level plants (angiospermae), oxidative depostional environment, non-hypersalin petroleum content, and the maturity level of oil from Bakau and Beruk are at the early maturity level.
