The present thesis discusses the geochemistry and maturation history of the upper cretaceous source rock of sirte formation in the eastern side of sirte basin, Libya. The study involves details on the evaluation of the kerogen type and richness in relation to the prevailed depositional environment. Thirty three cuttings samples were collected from three wells and two wells have not samples, namely; 23M1 - 593, 25P1-593, 23Y1 - 593, 25R1 - 593 and 25B1 - 593, hereafter abbreviated as A, B, C, D and E, respectively. According to the Rock - Eval results, the studied sediments are very good to perfect source rocks for oil and gas generation. The TOC richness and anoxic condition propose adequate preservation conditions. Kerogen belongs to type II or mixed type II and III (oil and gas condensate). Tmax and predication index evaluation indicate that maturity of the study source rocks occur between immature or / and early mature oil zone and at the beginning of the oil - producing stage
