“…Isocadalene formed at high temperatures was a more stable isomer than cadalene [57]. Therefore, the high intensity of cadalene compared to isocadalene indicates the low maturity of the Polaman sample [58][59]. A high abundance of the compound cadalene was also found in the coal of the Kutai Basin, Indonesia [53].…”

A study of the sedimentary rocks of the Ngrayong formation has been carried out on five samples from the Polaman outcrop point to determine the potential of coal as a source rock for producing oil and gas through GC-MS analysis. Biomarker analysis shows the presence of n-alkanes (C16-C36) with a bimodal distribution, indicating that the source of organic material in sedimentary rocks comes from bacteria, algae, and vascular plants, which is supported by several parameters such as CPI, OEP, LHCPI, wax index, ACL and AlkTerr values. This dominant source of terrigenous organic matter is also proven by the TAR value, C31/C19, C29/C17 ratio, and several aromatic compounds and their derivatives. Bacterial input as an organic source of allouchtonic sedimentary rocks is also proven by the presence of hopanoid, de-A-lupane biomarkers, and C17/C31 ratio. The oxic deposition environment is indicated by the Pr/Ph ratio. CPI and OEP parameters, C29 bb/ab ratio > 0.15 and C31 22S/(22S+22R) < 1 indicate low maturity of the sediment sample. Several parameters and the presence of biomarkers stated above conclude that Ngrayong coal as a source rock has the potential to produce oil and gas.

The energy demand increased dramatically owing to the evolution of industrial and domestic requirements and the associated decrease in oil and gas resources. This study aims to evaluate El-Maghara coal (with about 52 MT reserve) as a potential hydrocarbon source. The collect samples were subjected to petrographic, chemical analyses and Rock–Eval pyrolysis to investigate the detailed characteristics of this coal. Chemically, this coal is high volatile bituminous coal with high H and S content. The high H/C ratio indicates the high extraction yield of coal. The main maceral group in the studied samples is vitrinite (62.8%) followed by liptinite (31.3%) and inertinite (5.8%). The content of liptinite indicates the capability of this coal for petroleum production. Based on Rock–Eval Pyrolysis results and TOC content, the coal has excellent petroleum potential. The hydrogen index (HI) and H/C atomic ratio indicate the II kerogen type (oil prone) of this coal. This coal has Tmax and vitrinite reflectance values around 415.8 °C and 0.37%, respectively, indicating the immature stage of kerogen. The high reactive maceral content (94.2%), oil-yield (65.5%) and conversion from coal to oil (95.4%), indicated that this coal has a hydrocarbon generation potential for oil.
