In the present study, well logs and petrophysical core data are integrated to analyze Abu Roash (G) reservoir characteristics in Karama oil field, North Western Desert, Egypt. Conventional core data analysis of about 64 samples from Karama-4 well had been used in characteristic evaluation of the target reservoir. These data include permeability (horizontal and vertical), porosity (helium and fluid summation), and matrix density. The available core data were used to generate statistical analysis, histograms and new relations for porosity, and permeability data. The core analysis results show fair porosity and permeability values where the lithology is mainly carbonate (limestone and dolomite) with some sandstone. Well logging data of 4 wells were analyzed to evaluate the reservoir petrophysical parameters. These parameters include gross thickness, net pay, effective porosity, shale volume, water saturation, and hydrocarbon saturation. These reservoir parameters are mapped to illustrate vertical plotting and the aerial distribution. The aerial distribution maps showed that the best locations of hydrocarbon accumulation are at south, southeastern, and southwestern directions of study area. The petrophysical parameters also offered in the form of vertical variation logs (vertical litho saturation cross plots). They indicate that the lithology is intercalations of carbonate, mud, and sand streaks. In sand streaks, there is an observed increasing in the values of total and effective porosities and hydrocarbon saturation as well as decreasing in shale volume and water saturation. The results give an impression that the sand streaks in the studied formation are good reservoirs where the effective porosity ranges from 18.3 to 33.3% and the hydrocarbon saturation reaches up to 61.5% in in some zones in the different wells.
