Abstract

The Scarab Field, in West Delta Deep Marine concession, represents deep marine slope channels in Nile Delta of Egypt. The main hydrocarbon bearing formation is the Late Pliocene El Wastani Formation. Channel-1 and channel-2 of the El Wastani Formation are considered as the main reservoirs of Scarab Field. Well log data analysis, of four wells were accomplished using computer software programs (e.g. Interactive petrophysics (I.P. V. 3.6) software was used in petrophysical evaluation Petrophysical analysis, in terms of determining the effective porosity, shale volume, and reservoir fluid saturation of Channel-1 and channel-2 of El Wastani Formation, is the primary aim of this study in order to achieve better determination of the reservoir quality in Scarab Field. We found that Channel-1 and channel-2 of El Wastani Formation are having high storage capacity properties permit them of bearing a considerable amount of hydrocarbon fluids in the Scarab Field. It was found that effective porosity in chaneel-1 ranges between 18% and 30%, shale content ranges between 20% and 30%, the water saturation ranges between 36% and 52% in channel -2 the effective porosity ranges between 22% and 25%, shale content ranges between 20% and 30%, the water saturation ranges between 40% and 52.5% It is clear that the facies effect is the main factor that is controlling the distribution of the petrophysical properties.
