Source rock evaluation is one of the important tools in petroleum exploration which determine how and where the organic matter in the sediment is converted into hydrocarbons (Gas and/or Oil). Many geochemical factors play important role in that transformation such as temperature, pressure, bacterial activity, catalytic action, time and existence of geochemical medium with certain PH and EH value.
This study deals with the geochemical criteria of Zeit Bay Field, Gulf of Suez and the nearby areas to determine its source rock potentiality. The field represents one of the complicated oil fields as it comprises several reservoirs in complete hydraulic communication, making it one of the unique reservoirs. Hydrocarbons are produced from all the porous and permeable intervals from Hammam Faraun member of Belayim Formation down to Pre-Cambrian Fracture Basement. The determination of its source rock had been done through the interpretation of the geochemical analysis that carried out by geochemical lab, further more, to discus the reservoir potential of the field
Organic carbon content (type and quality), free bitumen content, vitrinite reflectance which reflect the thermal maturation Index and the hydrocarbon Index had been used as geochemical parameters in this study.
A correlation between Zeit Bay Field crude oil analysis and different rock samples had been performed to relate the crude oil to its proper source rock.
