Interactive Petrophysics (IP) input well log data and output results for Alam El Bueib-3A Member in Safir-N07 well showing oil column above oil water contact (O.W.C) at 8222.5 ft
Source publication
Safir Oil Field which locates within Shushan Basin is considered one of the well-known oil fields in northern Western Desert of Egypt. Alam El Bueib 3A Member is the main oil producer in this field. This member in Safir-N07 well has water saturation (Sw) values less than 40% with 17% porosity. However, the available data of Drill Stem Test (DST) in...

... using neutrondensity cross-plot with gamma ray of the interest zone of AEB-3A Member (8217.5-8222.5 ft), Safir-N07 well, Safir Field, north Western Desert, Egypt, showing sandstone is the main lithology traditional interpretation for AEB-3A Member, Safir-N07 well through Interactive Petrophysics (IP), is presented as lithosaturation plot (Fig. 5). Accordingly, oil water contact (OWC) is located at 8222.5 ft. Above this contact, 5 ft oil column is seen with moved hydrocarbon. All calculations indicated good oil ...

... High Large oil and gas accumulations are a remarkable feature of the Shushan Basin, North Egypt and show potential hydrocarbons within the sandstone intervals of the Bahariya Formation (EGPC 1992;Dolson et al. 2001;Metwalli et al. 2018;Elhossainy et al. 2021). Meanwhile, the Abu Roash rock unit (G Member) represents a significant potential source rock and extends widely in northern Egypt. ...
The current work can produce an updated quantitative analysis and prospective paleoenvironment reconstruction from Tut oil Field, Shushan Basin to evaluate the hydrocarbon reservoirs in space and times for further development plans and modelling in the Tethyan regime. Two sporomorph interval zones (Classopollis brasiliensis and Afropollis jardinus), and one total foraminiferal Range Zone (Thomasinella punica) are proposed. Three palynofacies assemblages are differentiated using cluster analysis of the different palynofacies parameters. The paleoenvironmental conditions during the Cenomanian age were reconstructed. Palynofacies assemblage I of the Baharyia Formation suggests a marginally dysoxic-oxic basin environment with a common occurrence of ostracods and terrestrial organic matter, while palynofacies assemblage II reflects the high abundance of dinoflagellate cysts, suggesting a suboxic-anoxic middle neritic environment. Palynofacies assemblage III of the upper part of Abu Roash G Member represents a relatively deep water inner-middle neritic environment. Three 3rd order significant sequences separated by two hiatus surfaces (Ce3 and Ce4) are described and correlated with the global eustatic sea-level. The hydrocarbon evaluation results show that the samples from the Abu Roash G Member contain oil-prone material of kerogen type II, while the samples of the Baharyia Formation are characterized by kerogen type III (gas-prone). Spore coloration analysis reveals that the samples from the studied formations are too immature to produce gas or oil and are ineffective as sources of hydrocarbon.
