In order to study the origin and the characteristics of the oil from the oil seepage area and the source rock the geochemical approaches are considered to be the most appropriate tools of all. The geochemical approaches of Total Organic Carbon Content (TOC), Fourier Transform Infrared spectroscopy (FTIR) and Ultravioletvisible spectroscopy (UV-Vis) will be the main analyses in this project in which the study area was conducted at the oil seepage of the transect area located in the Miri Formation, Sarawak. The Miri Hill structure is considered to be an asymmetric, slightly overturned, northeast-trending anticline, bounded to the southeast by a set of northwest-hading steep normal faults, of which the Shell Hill Fault. Miri Formation is mainly composed of underlying argillaceous Setap Shale with the upper part is dominated by arenaceous sandstone. The oil – source rock correlation will be carried out by studying the rock samples of the source rock, the Setap Shale of different beds and the oil seepage found at the seepage area. The similarities in terms of the chemical composition of the source rock and the oil seepage will be observed and discussed. The samples were taken from three study areas. The oil seepage area is located at 4°24'04.5"N, 113°59'57.1"E and the shale sample areas are located at 4°22'53.8"N, 113°59'27.1"E and 3°48'37.1"N, 113°44'25.8"E. These three areas will be the main study areas of this project.
