| Abstract | ||||
| In this work, Leveret J function methodology has been found ideal in characterizing water saturation within the reservoir and modeling fluid saturation profiles through a calculated software equation.Accordingly, the core capillary pressure data has been studied for the upper member of Bahariya Formation of Lower Cenomanian age (El-bassyouni and Abdullah, 1989) in Falak oil field area by plotting the capillary pressure of porous plate method versus the water saturation at which the pressure was applied, then capillary pressure curves were converted to reservoir condition in order to have more realistic capillary pressure curves similar to the reservoir conditions. The capillary pressure data were converted to height curves to simulate the reservoir fluid saturation along the depths above the free water level. Consequently, all the height curves that were plotted against the water saturation were normalized in order to have only one equation which directly represents the saturation profile in any well without using the resistivity tool data. Leveret J function has been used to extract an equation in this normalization process through the interactive petrophysics software. The extracted equation, with a correlation coefficient reaches (92%) has been used to calculate the water saturation from this modeling process. The water saturation coefficients achieved for the upper member of Bahariya Formation in 4 wells in Falak oil field were correlated with the water saturation coefficients derived from log interpretation and were found to be in a very good match. Hence,the proposed equation could be safely used to obtain the water saturation and accordingly hydrocarbon volume for any other un-cored intervals in any upcoming wells within Falak area without resistivity inpu | ||||
