Abstract
West Esh El Mallaha area is located at the southern onshore part of Gulf of Suez (GOS) and extended to about 52 km2. The main objective of this article is to extract the most important petrophysical parameters of sedimentary sequence to evaluate and define the hydrocarbon potentiality in WEEM area using the available well log data suite. The lithology of each reservoir were detected by using combination of different logs and different cross-plots including "Neutron-Density Cross-Plot" and" M-N Cross plot" respectively. Four wells were selected for the study, Tawoos-1, R-4, RE-2 and RE-22 which represent most of the study area. The results of the interpretation indicated that pre rift reservoirs sediment "Nubia, Matulla" are composed of coarse to fine grained sandstone with fair to poor sorting. Shale inter-beds are common and some wells show carbonate layer in the upper Nubia-A. The post-rift reservoir sediment "Nukhul is considered one of the main reservoirs in our study area. Its main lithology is Sandstone, dolomite and, Limestone as well as the presence of shale. The majority of point distributed as carbonate (dolomite and limestone) with some of it back to the effect of clay minerals and calcareous cement. Different Cross Plots indicated the abundance of dolomite and limestone with minor occurrence of sand stone. The presence of high shale content in Rudies fm. shifted the point downward in M-N Cross plot. This reveals that the reservoir encountered is highly calcareous sandstone.
