Description
Summary:A collection of 14 crude oil samples representing 13 giant oil fields from the prerift and synrift reservoirs of the Gulf of Suez province were analyzed for C7 light hydrocarbons. The light hydrocarbon parameters C7 star plot diagrams in conjunction with the biomarker characteristics differences were used to distinguish the Gulf of Suez into two oil groups, the prerift and synrift oils, which are predominantly source related and maturity dependent. The biomarker properties indicate that the prerift oils exhibit oleanane index < 8%, and higher gammacerane index > 23%, while the synrift oils are characterized by relatively higher oleanane index around 30% and low gammacerane index values < 10%.
