Four crude oil samples recovered from some producing wells in the southern part of the Egyptian Gulf of Suez were subjected for measuring some organic geochemical parameters. Biomarkers are biological markers such as Terpanes and steranes of the saturated hydrocarbons obtained by gas chromatography-mass spectorometry (GC-MS). In addition to n-alkanes and isoprenoids distributions obtained by gas chromatography (GC). Terpanes biomarker distributions ( m/z 191) mass chromatograms for oil samples is revealing marine organic facies of depositional environmental and maturation parameter. Hopane distributions (m/z = 191) indicates the marine organic sources. The steranes distributions for the oil samples (m/z 217) suggest a pre Tertiary source rocks for these oil samples.
