Abstract

DOI: 10.17014/ijog.v1i1.175The Oligocene Sinamar Formation consists of shale, claystone, mudstone, sandstone, conglomeratic sandstone, and intercalation of coal seams. The objective of study was to identify the hydrocarbon source rock potential of the Sinamar Formation based on geochemichal characteristics. The analyses were focused on fine sediments of the Sinamar Formation comprising shale, claystone, and mudstone. Primary data collected from the Sinamar Formation well and outcrops were analyzed according to TOC, pyrolisis analysis, and gas chromatography - mass spectometry of normal alkanes that include isoprenoids and sterane. The TOC value indicates a very well category. Based on TOC versus Pyrolysis Yields (PY) diagram, the shales of Sinamar Formation are included into oil prone source rock potential with good to excellent categories. Fine sediments of the Sinamar Formation tend to produce oil and gas originated from kerogen types I and III. The shales tend to generate oil than claystone and mudstone and therefore they are included into a potential source rock.

Abstract

This study focuses on correlation of liptinite and vitrinite maceral to kerogen type of shale from Kelesa Formation in Kuburan Panjang areas, Sumai sub-basin, Central Sumatra Basin. The composition of the organic material consists of vitrinite maceral ranged from 0.2 to 5%, liptinite from 0.6 to 4.7%, the type of minerals in the form of pyrite from 0.2 to 16%, and 0.2 -24.2% of carbonate, as well as clay minerals are the most dominant component ranged between 71.6 -98%. TOC values of the shale range from 1.18% to 7.17%, which indicate ability of the shale as a good source rock. Kerogen type analysis of theshale in the research area tends to indicate I, II and III kerogen types. There is an influence of the liptinite and vitrinite maceral groups abundance to the type of kerogen, where liptinit maceral group tends to produce type I and II kerogen.

Abstract

In this study, we apply organic geochemistry analysis for evaluating source rocks in Gunung Bayan Areas, West Kutai Basin. Subject of this research are Oligocene fine-grained sedimentary rocks of Pamaluan Formation on Gunung Bayan Areas. The Oligosen fine-grained sedimentary rock of Pamaluan Formation consists of shale, siltstone and claystone. The organic geochemistry analysis includes pyrolysis data as total organic carbon(TOC%), generating source potential (S2), production index (PI), oxygen and hydrogen indices(OI, HI) and (Tmax). The results show that the Oligocene source rocks have poor into good quality with type III kerogen and have true capability to generate  gas. The source rocks candidate is  characterized by HI 5 - 115 (mg/g), TOC from 0.19 to 1.78 wt%, S1 from 0.01 to 0.09 (mg/g) and S2 from 0.05 to 1.74 (mg/g) that indicating poor to fair source rocks with type III kerogen and capable of generate  gas. The maturity of the fine-grained sedimentary rocks tend to indicate immature to mature stage. Overall fine-grained sedimentary rocks of Pamaluan Formation has capability to produced gas with poor to fair quality.
