Geochemical Evaluation of Source Rocks in the Sirte Shale Formation, Concession NC98, Southeastern Sirte Basin, Libya

Abstract

This project presents a geochemical study aimed at evaluating the source rocks of the Sirte Shale Formation within the NC-98 Concession, located in the southeastern part of the Sirte Basin, Libya. The main objective was to assess the hydrocarbon source potential of these rocks. The Sirte Basin is one of the most important oil basins in Libya and Africa. It contains vast high-quality oil reserves and thousands of productive wells, making it a major center for exploration and production activities. This study analyzed 15 rock samples collected from three different locations within the concession area, using advanced techniques such as Total Organic Carbon (TOC) analysis and Rock-Eval pyrolysis. These analyses provide valuable information on organic matter content, kerogen type, and thermal maturity, which are essential factors in determining the capability of rocks to generate hydrocarbons. The study concluded that the rocks of the Sirte Shale Formation, particularly the upper part, possess favorable characteristics as hydrocarbon source rocks. This indicates that the area is promising for future exploration. The study recommends intensifying research and exploration efforts in the region using modern and advanced techniques to identify optimal production sites, thereby enhancing investment opportunities in the Libyan oil sector and supporting the sustainability of national resources.
