A New hydrocarbon Prospect Determination Through Seismic Interpretation and Petrophysical Evaluation of Bahariya Reservoir in Nader field, North Western Desert, Egypt

The goal of this research is to carry out a subsurface and petrophysical investigation to estimate the petroleum potential of the Bahariya reservoir in the Nader Field of the Khalda Ridge concession in Egypt's northwestern desert. This study depends on using the composite logs for four wells, Nader-1, Nader-2, Nader-4, and Nader-8, and twenty (2D) seismic lines. The Bahariya Formation unconformably underlies and overlies the Abu Roash and Kharita formations, respectively. The Upper and Lower Bahariya formations were evaluated as the petroleum sandstone reservoirs in the studied field. Seismic interpretations were used to clarify the structural settings on the tops of these formations. These formations' time-and-depth-structure maps reveal a variety of structural features which aid in prospect identification and hydrocarbon potential in the area. The petrophysical evaluation involves lithology identification, reservoir pressure measurements, and determinations of petrophysical parameters such as effective porosity (PHIE), net-pay thickness, water saturation (S w ), shale content (V sh ), and hydrocarbon saturation (S h ). The results of this study revealed three new proposed locations to the southeast and north of the investigated Nader field. These locations are located on appropriate structures and on four- or three-way dip structural closures that are suitable for petroleum accumulations. They also have a decrease in V sh and S w , and an increase in net pay, PHIE, and S h for the Upper and Lower Bahariya reservoirs. As a result, it is advised to concentrate exploration efforts on new promising locations for more economical petroleum discoveries.
