Evaluation of the source rock potential of the Unyazah Formation (late Carboniferous-Early Permian) in Dukhan Field, Qatar
Twenty samples were collected from the Unayzah Formation in three wells from Dukhan Field, Qatar. Many samples were of poor quality due to the low TOC content containing gas prone-kerogen type III and IV. The Rock-Eval maturity parameters indicate that many samples were immature, while the mature samples generated dry gas. The C15+ extracts GC suggests a marine input, while they have kerogen type III and IV which are usually derived from terrestrial input. This may be due to the abundance of G. Prisca which was probably recycled from older sediments. The organic matter may also have been subjected to oxidation, leaching, biodegradation or recycling due to the changing nature of the depositional environment that ranged from braided river system to marine settings.
