The Bahariya Formation is considered as a crucial hydrocarbon reservoir in AES-E3 on the East Alam El-Shawish Field, North Western Desert of Egypt. This work aims to illustrate the impact of Petrophysical characteristics and subsurface features on Bahariya reservoir development through the integration of petrophysical analysis and seismic interpretation. The seismic interpretation displays Bahariya reservoir structure as a series of normal faults separating the area into deferent segments represented by two to three-way dip closure which considered as the main structures in the East Alam El-Shawish field. Petrel and Tech Log software was used for analysis and mapping the five well logs, to provide the lithology and fluid saturations for Bahariya reservoir. Also, the effect of geological features in the development of the area study was clarified. East Alam El-Shawish area has excessive porosity and hydrocarbon saturation values because of the massive fracturing resulting from faulting supported by high structural position, porosity, high percentage of hydrocarbon saturation and both low shale content and water saturation. This helps and encourages drilling lots of development and appraisal wells in north east, south east and central parts at the area of study to increase oil production. Consequently, the integration between the petro-physical characteristics and geological structures will be helpful for the development and increasing productivity of the study area.
