Petroleum geochemistry of Harshah formation from Bahr Essalam Field, Sabratah Basin, NW Libya

الملخص EN

The goal of this work is to discuss the crude oil in the Harshah Formation (reservoir) in well C2-NC42 from Bahr Essalam Field, Sabratah Basin, NW Libya.

Based on API classification the crude oil samples are classified mainly light oil type.

The organic matter is characterized by thermally mature and were deposited in an open marine environment formed in suboxic condition.

The methyl cyclohexane/toluene (Mch/Tol) vs cyclohexane/ benzene (Ch/B) ratios revealed that crude oil is affected by evaporative fractionation.
