APPLICATION OF WELLLOG TOOLS AND ORGANIC GEOCHEMISTRY IN SOURCE ROCK IDENTIFICATION, SOUTHERN GULF OF SUEZ, EGYPT

In order to evaluate the source rock a combination between resistivity measurements from one hand and sonic, density, neutron and level of organic metamorphism (LOM) from the other is carried out in an area located at the southern part of the Gulf of Suez-Egypt. The methods described by Meyer and Nederlof (1984) and by Passey et al. (1989 and 1990) was applied as analytical techniques. Calculations were done using the equations given by Meyer and Nederlof, then the results obtained are correlated with the results obtained from the ƒxlogR mthod which is applied in three steps i) Calculation of ƒxlogR using the overlay relation between resistivity parameter and each of the other measured log parameters and ii) calculation of TOC% using the obtained ƒxlogR and LOM values calculated using the method described by Hood et al (1975) and some geochemical data. The method is applied on three wells scattered in the study areaand covering Middle and Lower Miocene section. Correlation between the results obtained from log analysis and geochemical information proved that both methods could be applied successfully in this case.
