Reservoir characterization of the Upper Cretaceous Abu Roash "G" Member, using wire line logs and 3D seismic data in West of Nile-X Field, Beni-Suef Basin, Western Desert, Egypt.

The current work focuses on integration of seismic and well log data for evaluating the Upper Abu Roash “G” Sand Member, in West of Nile-X oil field. A comprehensive petrophysical evaluation was performed for Abu Roash G reservoir. The estimated petrophysical parameters of the reservoir in the study area for the Upper Abu Roash”G” Sand Member range between about 17 % and 22 % for the effective porosity, and range between about 5 % and 15 % for shale volume, and range between about 18 % and 79 % for Water saturation. All of These results show that the Upper Abu Roash ”G” Sand Member in this field deem as a good reservoir with high potential for oil production and the cumulative stock tank of original oil in place estimate for the study area is 27 Million Stock Tank Barrel. Depth structure map shows an elongated asymmetrical double plunging anticlinal has an axis of NNE-SSW trend with a steep dip value in the eastern part and a gentle dip in the western part of the study area, which formed petroleum traps in the crest of the study area. The study results show that the Upper Abu Roash ”G” Sand Member has a promosing reservoir characterization.
