Two main reservoirs are producing in Komombo Basin: the first one belongs to the C Member of the Six Hills Formation, and the second belongs to the Albian/Cenomanian cycle. The C Member reservoir lacks detailed studies. Therefore, a detailed study of this reservoir is needed. 3D geological reservoir modeling of the C Member reservoir can be a pertinent part of an overall strategy for the development of hydrocarbon fields in Komombo Basin. Five boreholes, three vertical seismic profiles and twenty 2D seismic reflection sections are integrated in Petrel™ modeling software for building 3D structural, facies and petrophysical models for the C Member reservoir. The constructed 3D structural model reveals the presence of two normal faults, in NW–SE and NE–SW directions. A detailed petrophysical evaluation was performed for the available wells. The resulted facies/petrophysical parameters are then used as input in the processes of facies and petrophysical modeling. The C Member reservoir exhibits thickness values ranging from about 91.5 to 426.5 m. The constructed 3D facies model of the studied reservoir depicts that the shale beds have the large probability distribution in the study area with the comparison of the sandstone and siltstone beds. The created 3D petrophysical models reveal that the C Member reservoir has a fair reservoir quality. This reservoir exhibits, generally, high water saturation values in most parts of the study area, while the hydrocarbon saturation is restricted to the depocenter of the basin.

Bisphenol A (BPA) is a chemical material that using in polycarbonate
plastic that is widely used in daily life items. Several studies showed the
adverse effect on the health of erythrocytes in both human and animals, while
gallic acid (GA) is a known antioxidant capable of counteracting free radicals.
In this study included 4 groups 10 rats each. The first was the control. The
second received BPA in drinking water was given ad libitum at dose
40mg/kg.b.w. The third and fourth groups was given BPA by the same dose
and by the same route in addition to receive GA in the diet at doses of 50 and
200 mg/kg.b.w, respectively. In erythrocytic hemolysate, the antioxidants:
glutathione (GSH), activities of both superoxide dismutase (SOD) and catalase
(CAT) were estimated. Also, lipid peroxidation (LPO) and carbonyl protein
(CrPr) were determined. The results showed that BPA significantly increased
LPO and CrPr and decreased the activities of CAT, SOD and the GSH
content. However, the treatments of the BPA-intoxicated rats with GA
reversed the erythrocytic oxidative damage and curtailed the decrease in
antioxidants. In conclusion, the GA with both doses could attenuate the
oxidative damage in erythrocytes of rats-treated with BPA.
