The study area is located in northwest Murzuq Basin in the Atshan Field within NC 151 and includes F1 and C1 wells. This research aims to investigate the geochemical properties of Tanezzuft formation by using Rock Eval analysis to evaluate organic matter and potential generation of hydrocarbon. Result of analysis show values of Total organic carbon (TOC) range from (0.45% to 1.26%) which suggests total organic matter ranges from fair to good, The Hydrogen Index indicates the dominance of Type III kerogen of continental origin, while the Tmax values range from 436 to 452 °C, indicating that the organic matter has reached the oil generation stage (oil window). Furthermore, the relatively low Oil Saturation Index (OSI) values suggest that the Tanezzuft Formation has low saturation potential for unconventional hydrocarbons (shale oil).
