The purpose of this paper is mainly to apply a complete workflow for a petrophysical evaluation to enhance and quantify hydrocarbon prospect and productivity of West Wadi El Rayan field in Abo El Gharadig Basin, Western Desert, Egypt through the quantitative interpretation of the logging data for WD38-1 well. The litho-saturation model will be created for WD38-1 well, so that at each depth, the volume of shale, matrix, water and hydrocarbon could be determined. This model provides a direct technique for the quantitative interpretation for the petrophysical parameters, such as shale volume (𝑉𝑠ℎ), porosity (∅) and fluid saturations (𝑆𝑤 and 𝑆ℎ), which are the most important for the geologists, geophysicists, petrophysicists and petroleum engineers.
