Generation, migration and accumulation of oil of El-Ayun Field, Gulf of Suez, Egypt

Abstract

This study is an attempt to solve the problem of oil generation, migration and accumulation of oil in El-Ayun Field, Gulf of Suez. The organic carbon, hydrogen and organic matter contents in addition to the composition of kerogen are determined. The degree of transformation of organic matter to hydrocarbon and the level of thermal maturity of these sediments to yield hydrocarbons are deduced. The geothermal gradient mnd level of organic metamorphism (LOM) are determined by using the bottom hole temperature. The vitrinite reflectance values are used in this respect. The determined trace element contents for both crude oils and sediments clarifies the process of oil migration from possible source rocks to oil reservoirs. Recommendations, concerning exploratory testing of favourable sites for oil accumulation, laterally and vertically, are postulated on the basis of the achieved results. © 1987.
