Abstract: Since 1950’s Ghadames Basin is considered as a highly productive petroleum province with a long exploration history in Libya, Algeria, and Tunisia. The ongoing exploration efforts and success of this basin in these countries is a proof of its potential to provide attractive exploration targets in future. Most discoveries in the basin so far have been made in the Acacus Formation as primary target and Wan Kasa and Momenyiat formations as secondary target. As well as small discoveries have been made in the Tahara and Mrar, Ras Hamia and Tanezufft formations. The scope of this project was to study the distribution of Tahara and Mrar formations to look for new potential areas. To provide a better understanding of the structural and stratigraphic framework and regional hydrocarbon prospectivity, A regional N-S cross-section (700 km) through the Ghadames Basin was constructed by using LandMark StratWork software. The information shown on it is based on well logging data from 36 wells. These wells penetrated the Paleozoic sedimentary rocks and the crystalline basement. The correlation of the stratigraphic units between the wells was done using a variety of wireline logs (e.g. gamma-ray, spontaneous potential, resistivity and sonic). The sandstone units in the Tahara and Mrar formation could provide a good opportunity to explore for stratigraphic traps. These intervals are recommended for study in more details in the future using all the available information.
