The WON-X field was discovered in the western portion of the Beni Suef Basin in Egypt, which is now being investigated and exploited in the north of Western Desert, Egypt. Within this concession, the WON-X field is built in a way that makes it good at making hydrocarbons. One of the promising areas newly added to Egypt's strategy for future oil exploration is the West Beni Suef basin (WON-X). Interpolated seismic data-oriented NE-SW and passing through well faults, showing the faults that affected the research area, were oriented NE-SW and passed through wells. In an unconformable manner, the Lower Cretaceous, Albian Kharita Formation overlies the basement rocks. The original Nile was at the top of the seismic section, where the sediments were eroded in different ways until they reached Abu Roash E (A/R E) member. As a consequence of multiple drilled wells and the analysis of the well data such as the pressure measurement which were different in the southern and the northern parts of the field, it was possible to identify substantial lateral variations in the reservoir, such as stratigraphic barriers. Through the integration of seismic and geological well data, significant experience and a greater understanding of the Abu Roash (AR "G") reservoir potentiality have been gained in the WON-X oil field. The seismic attributes such as the RMS map may be used to detect the different compartments in the field as well as other geologic parameters whose amplitude response allows them to be isolated from background features. Additionally, the RMS map displays the stratigraphic mud barrier that formed between the wells in the study region. In addition to typical fault lines, the WON-X hydrocarbon oilfield is situated on a double plunging anticline, also known as an "asymmetrical anticline". According to maps of the AR "G" reservoir, the centre of this anticline is an ideal location for oil accumulation.
