Source Rock Evaluation and Maturity Levels of the Rudeis Formation, Northern Gulf of Suez, Egypt, Using Well Log Analysis and Rock-Eval Pyrolysis

Gamma-ray, density, sonic, resistivity and neutron are the commonly used wireline logs to identify and quantify source rocks. Several models were developed to use the conventional wireline logs for evaluating the thermal maturity of the source rocks and calculating the total organic carbon (TOC) content. Application of Schmockr and Hester (1) approach with some required modifications for the Rudeis Formation, Northern Gulf of Suez, Egypt, is the main purpose of this paper. The results, which compared with those obtained from the Rock-Eval pyrolysis, show that cautions must be taken into consideration when applying this model, because most of the models reflect empirical relatinoships and their validation takes place under certain conditions. It can be concluded that, the Rudeis Formation represents fair source rock potential with type III kerogen and terrestrial supply of the organic matter and is marginally mature for the generation of minor amounts of oil and gas.
