Abstract

Summary

In this study, the coals and shales sediments of Miocene Bongaya Formation have been evaluated for their source rock potential using geochemical methods. Bongaya Formation consisted of sandstones interbedded with carbonaceous shales that occur in isolated basins on top of older sediments such as Crocker, Kudat and Chert-Spillite Formation. The results were used to characterize organic geochemical properties of coals and shales in the formation of determining their thermal maturation, organic richness, and quality of organic matter. Pyrolysis, bulk analysis as well as petrographic analysis were also performed on the samples. Based on geochemical and pyrolysis results, the samples suggest that Bongaya Formation is a dominant Type III kerogen with minor Type II kerogen shown mainly gas prone with minor oil generative potential. The formation also indicates a good and rich source rock but with a low thermal maturity level measured from both optical analysis and Tmax value.
