The Kutai Basin is one of the most important basins in Indonesia. This basin has an area of ± 16,000 km2 and contains deposits of Tertiary age with a thickness of up to 14 km. This study focuses on analyzing the quantity and type of source rock organic material in the Kampung Baru Formation and the Pulaubalang Formation. Based on geochemical analysis, it can determine the quantity of organic material, the type of organic material in the Lower Kutai Basin. By using parameters, namely, TOC (Total Organic Carbon), HI (Hydrogen Index), Depth, Tmax (Maximum Temperature), PY (Yield Potential). Based on the results of the study, the analysis of the TOC value in the Kampung Baru Formation shows the quantity of source rock is good - special, with a TOC value of 1.57 - 50.99 wt.%. while the Pulaubalang Formation ranges from moderate to excellent, with a TOC value of 0.64 - 67.25 wt.%. The kerogen type in the Kampung Baru Formation and the Pulaubalang Formation shows kerogen type III and Kerogen type II/IIIb, producing gas and oil or gas (Mixed)
