Abstract

Organic petrology is the key study to identify the favorable geological condition of black shale as a hydrocarbon source rock. The study aims to identify the organic matter types in the black shale of Bokor Formation, Kampot province. Three outcrop cross-sections (Phnom Khley, Phnom Chakrey, and Phnom Monprey), which extend from the West to the East of Kampot province, were investigated for stratigraphic sequences, sedimentary structures/textures, fossil contents through fieldwork observation. Rock sampling was conducted to performed polish pellet for organic petrology. The result demonstrated that the western part consisted of repeated sequences of thin laminated shale layers interbedded with massive sandstone layers. In the eastern part, the shale layers are continually deposited as a thick bedding with fossils of syringopora, crinoid, and foraminifera, which indicates a low energy flow environment during sediment deposition. Organic petrologic analysis in shale samples revealed that alginate and bituminite were dominantly found shale samples in the Phnom Khley section, whereas macrinite and vitrinite were observed in Phnom Monprey and Phnom Chakrey, respectively. The presence of alginate, bituminite, and macrinite, suggest a potential for hydrocarbon source rock. The maceral types, such as alginite, bituminite, micrinite, and vitrinite, indicate deposition in periodically oxygenated bottom water and a sulfidic marine water environment. Based on the existing macerals and cubic pyrite that presented in the collected samples, those source rocks are suggested as thermally mature petroleum source rock.
