Abstract

saffron Gas Field, situated within the West Delta Deep Marine (WDDM) concession on the north-western margin of the Nile Delta. The hydrocarbons in this field are extracted from the Saffron sand reservoirs. Many wells have been drilled and have penetrated these reservoirs. The petrophysical evaluation, conducted using well-log data, aims to identify hydrocarbon-bearing reservoirs and examine reservoir properties based on data from four wells. This study utilizes the Tech-log Schlumberger software packages for its analyses.
The four wells provided ample data for detailed analysis, allowing evaluation of some petrophysical parameters such as shale volume (Vsh), total porosity (PHT), effective porosity (PHE), water saturation (Sw), hydrocarbon saturation (Sh), and net-to-gross reservoir thickness. Both conventional log tools and advanced CMR tools (Combinable magnetic resonance) were used in the present study, with a comparison between traditional and advanced techniques.
