Abstract

The Sab'atayn Basin has the greatest oil and gas exploration potential in the Mesozoic basins of Yemen. The quantity and quality of the organic matter of sediments is a core focus of source rocks evaluation in exploration of hydrocarbon. Organic-rich sediments within the Meem (Lower) and Lam (Upper) members from four wells in the NW Sab'atayn basin were analyzed using organic geochemistry and total organic carbon content. The obtained data shows that the total organic carbon content (TOC) values from Meem source rocks are between 0.2 to 1.68 wt% indicating fair to very good source rocks. While the values for the Lam source rocks are between 0.2 to 3.81 wt% indicating excellent source rocks, only two samples have values more than 3 wt% in Kamaran-01 well. The Rock-Eval pyrolysis data reveals that most of the samples are consist of reworked organic matter with no interesting source rocks potential.
