The evaluation of the geochemical characteristics of the Jurassic and Cretaceous oils in
the study area revealed that these oils have high API gravity, low sulfur content and rich
in saturated hydrocarbon fractions. They are mature, with no biodegradation and belonging
to normal paraffinic waxy type. They were derived from mixed organic source, mainly
terrestrial (land plants).
The geochemical correlation among the productive oils and the extracts of the potential
sedimentary source beds of Khatatba (Jurassic), Alam ElBueib and Bahariya (Cretaceous)
Formations revealed a genetic close relationship among them and supported the indegenous
mixed source of these oils.
