Reservoir characterization of the Upper Cretaceous Abu Roash ‘G’ Member, using 3-D seismic data in the WON-X Oil Field, Beni Suef Basin, Western Desert, Egypt

Abstract

The WON-X field was discovered in the western area of Beni Suef Basin in Egypt, which is now being explored and exploited in the part of the northern Desert. Within this concession, the WON-X field is adopted to producing hydrocarbons successfully. The West Beni Suef basin is one of the prospective area recently added to Egypt's oil exploration strategy (WON-X). Interpolated seismic data oriented NE-SW and passed through well faults displayed the element that impacted the research area. The Lower Cretaceous Albian Kharita Fm, superimposes the foundation rocks in an unconformable form. The original Nile was at the top of the seismic section, where the sediments were eroded in a variety of methods, until they reached the Abu Roash E (A/R E) Member. It was feasible to find major lateral changes in the reservoir, such as stratigraphic barriers, as a result of many drilled wells evaluated, including pressure measurements, which differed between the southern and northern portions of the field. Through the integration of seismic and geological well log data, the WON-X oil field has obtained extensive knowledge and a deeper understanding of the potential of the Abu Roash (AR "G") reservoir. Seismic attributes such as the RMS map can be utilized, to discover various compartments in the field and the other geologic factors whose, amplitude responses allow them to be separated from the background features. In addition, the RMS map depicts the stratigraphic mud barrier that developed between the wells in the studied area. In addition to normal fault lines, the WON-X hydrocarbon oilfield is located on a doubly plunging anticline, commonly referred to as an "asymmetrical anticline." According to the maps of the AR "G" reservoir, this anticline's centre is a prime place for oil accumulation.
