GENERAL GEOLOGY AND HYDROCARBON POTENTIAL OF CARBONACEOUS SHALE IN KAMPUNG IBOK, CHUKAI, TERENGGANU

Abstract

Various chemical analyses such as Total Organic Carbon (TOC), Source Rock Analysis (SRA), Vitrinite Reectance (VR) and X-Ray Diraction (XRD) have been performed to study the properties of carbonaceous shale and its hydrocarbon potential at Kampung Ibok, Cukai, Terengganu. The TOC content of carbonaceous shale in Chukai area is ranging from 1.24% to 15.3% and increases towards southern part. This may indicate that the southern part might be the deepest part of shallow marine environment. The SRA conrms that the carbonaceous shale in the study area has poor capability in generating any hydrocarbon. However, the results from VR suggested that the shale could have the possibility in producing shale gas. Keywords: carbonaceous shale, shallow marine environment, hydrocarbon potential, shale gas
