The principal aim of this work is to study the petrophysical parameters in the area under investigation. The study is applied essentially on the Rudeis and Kareem formations in Ras Ghara oil field, Gulf of Suez, Egypt. The study of hydrocarbon potentialities is very important to understand the hydrocarbon situation in the study area by estimating the volume of shale, porosity and the water saturation. Petrophysical characteristics deduced from the process of well-log analysis are generally varied vertically through litho-saturation crossplots and laterally through iso-parametric maps. In this research, Tech-log software is used to evaluate the petrophysical characteristics of the studied formations in the form of litho-saturation plots which are considered as an important vertical representation because they are used for more accurate evaluation in the individual wells in the comparison between different wells.
