| Abstract | ||||
| A comprehensive petrophysical evaluation has been made in six wells in the BED-1 field which penetrated the Bahariya Formation, namely, BED 1-2, 1-3, 1-4, 1-5, 1-6 and 1-8.The study shows that the thickness of the net sand of the Lower Bahariya Formation ranges from 14 m to 78 m. The shale content is low (5.3 % to 16.9 %). The log-derived net/gross, porosity and water saturation calculated using all available raw logs. The petrophysical results can infer the hydrocarbon potentialities of this reservoir. From petrophysical analysis, it was found that, the porosity of the Lower Bahariya Formation varies from 8.8% to 11.2%, averaging 10.5%. The pores are filled with more than 74% of hydrocarbons. Also the permeability is between 0.07 to 1052 md, with an average value of 515 md as deduced from core analysis for the study wells. Furthermore, RFT pressure measurements indicate the presence of the two fluid gradients, one for oil (0.3 psi/ft) and the other for water (0.5 psi/ft), with a free water level at 3609 mss. Based on the study results it recommended that a development/exploration activity to be conducted to assess the Lower Bahariya Formation in the area of interest | ||||
