Oil-oil correlation for the oils recovered from Beni Suef
Concession suggests there are two oil groups .
Group I :
includes the oils that appear to be generated from
predominantly terrestrial organic matter and are
represented by Beni Suef-1X, Azhar -1X and Yusef -1X
oils. These oils appear to be generated at a high thermal
maturity ( Paraffinic waxy , high API & high Pour Point . )
Beni Suef Oils Correlation
Group II :
represented by Azhar -7X, Azhar E-1X, Sohba -1X and
Gharibon-1X oils appears to be generated from a
predominantly marine organic matter at moderate
thermal maturity ( API 25° , pour point Zero ).

Stratigraphic column of E.Desert is similar to W.Desert with the exception that Basin inception may be controlled by Aptian/Albian NE-SW extension and resulted in the Kharita Formation being deposited directly on basement.
Major part of Beni Suef basin is located in the East of Nile
Three oil discoveries were achieved based on 2D seismic interpretation and other three oil discoveries were achieved based on 3D seismic interpretation .
Conclusions
Geochemical studies confirmed presence of two oil families in Beni Suef basin, first is generated from lower Kharita shale & siltstones, second is generated from A/R “F”.
Basement is encountered in Azhar-2 & Azhar-5 more than 12¸000 ft which confirmed the presence of more than 1500 ft of shale & siltstone as an excellent source rock of lower Kharita.
Very high gas readings were recorded (more than 30%) while drilling L. Kharita shale & siltstones in Azhar field which could be a gas producer in future by using hydraulic frac.
The results of this work may be applied to the south for hydrocarbon potential of other basins such as Minya & Assyut of Upper Egypt.
Conduct required geological studies to evaluate lower Kharita shales & siltstones as gas producer.
Re-evalute any dry hole well data in the light of applying hydraulic frac. and in case of having encouraged results, study the visibility of re-enter or drill a twin well.
Conduct hydraulic frac. in case of having poor oil rate or oil slugs in the testing of an exploratory well .
