چکیده
Kampong Som Basin is a Paleozoic-Mesozoic sedimentary basin located in southern Cambodia. While the sandstone of Bokor Formation expected to be reservoir for hydrocarbon accumulation. Hence, this study aims define properties, quality, and factors that control rock quality. Sandstones are sampled analyzed using helium porosimeter, nitrogen permeameter, polarized light microscope, scanning electron microscope (SEM) check porosity, permeability, minerals, pore geometry, clay minerals influence According result petrography analysis described by thin section, samples from formation classified as quartz arenite composes mainly quartz, fragment, mica-flake, sericite with connected unconnected pores 50 μm 500 interparticle type. have porosity values ranging 6.55% 13.19%, permeability 10 mD 60 mD. The statistics reservoirs indicate low suggested fair SEM results there three types authigenic involving such kaolinite, illite, chlorite. In addition, overgrowth, dissolution felspar grain filling space, compaction, replacement diagenesis processes, cementation presence main controlling Formation. Furthermore, area exhibits structures planar cross-bedding, parallel lamination, normal grading, massive, wavy, reverse graded bedding, which indicates these lithofacies may deposited shallow marine environments.
