Abstract

This study focuses on the source rock evaluation and the hydrocarbon generation in the East Bahariya concession, the eastern trough of Abu Gharadig basin, Western Desert, Egypt. By using the available data from Yomna field a subsurface evaluation of the encountered stratigraphic rock unit was carried out. Geochemical analysis of source rock and oil to source correlation to support the hydrocarbon origin in reservoir in the study area. These analyses were executed to determine the organic and the effect of both structural & stratigraphic implications on the source rock, in order to conduct more activities in the study area. The main objective of this study is to evaluate the prospectively, hydrocarbon potentialities and petroleum system elements of the study area, deals mainly with the source rock evaluation and the hydrocarbon generation. Also present the petroleum system in the area such as reservoir, source rock with its maturation stages and the proposed migration path to enhance the productivity of the field and add more rooms or prospects. Detecting the efficiency of hydrocarbon expulsion from source areas to Reservoir in the study areas will open new rooms of prospect new locations of shallow reservoir.
It was concluded that the ARF Member, Khatatba and Alam El Bueib (AEB) formations are rich in organic matter with TOC mostly >2.00 % and both could be considered as an effective source rock for the oil presented in Yomna7a & 22 wells. Accordingly, we have a good opportunity to drill more development wells to enhancement the productivity of the study area.
