Petrophysical properties of well logs studies of cores from four wells including (F1, F2, G1 and A1) penetrating the Beda”C member of The Beda Formation at depths from , 8800-9245ft, 9050 - 9250 ft, 9052- 9370ft and 8180-8500ft consecutively, indicated that the Beda”C member represents a carbonate sequence that underwent shallowing from open marine to restricted water. The progradational nature of the Beda”C Member however, allows a long distance correlation for different horizons.

From through petrophysical properties calculations explain porosity and permeability increases with dolomitization but decreases with rise shale and depth. From examination water and oil saturation can determination oil, shale and water zones.The reservoir potential of the Beda”C Member is controlled by several geological factors, such as paleogeography, daigenesis and structure.

From comper btween zonitons, porosity calculition and type lithology we can see absence of dolomite in A1well, changes in the porosity which are good in F1 and G1 wells and differant SO and oil zone btween F1 and G1wells are good but A1well is low.
