| Abstract | ||||
| Belayim Land oil field is considered as one of the largest oil fields in the Suez rift. This field is located at the central part of the Gulf of Suez, along the western coast of Sinai Peninsula. It lies to the east of Belayim Marine oil field. The present study deals with an integrated seismic interpretation and well-log analysis using Interactive Petrophysics computer program for Kareem Formation. The interpretation of seismic data has been done using Seis Works software (Halliburton) and represented with three seismic sections. The available well – log digital data are resistivity (deep and shallow), porosity (sonic, density and neutron), gamma-ray and composite logs for nine scattered wells (112-50, 112-54, 113-14, 113-24, 113-32-tri, 113-69, 113-A-12 & 113-A-32ST) to evaluate the different petrophysical characteristics available computer software. The petrophysical characteristics deduced from the process of well-log analysis are generally varying vertically and laterally. The lateral variation of petrophysical characteristic in the area under investigation could be studied through a number of gradient maps (iso-parametric maps); that include, shale content (Vsh %), effective thickness (Heff m), effective porosity (Øeff %) and hydrocarbon saturation (Shr %) to complete the vision of hydrocarbon potentialities in the studied area. The vertical distribution of petrophysical characteristics have been performed through the litho-saturation computerized cross-plots in the form of petrophysical data logs (PDL). The litho-saturation cross-plots may be considered as an important vertical representation for petrophysical characteristics, because they are used for more accurate evaluation for each individual well and in the comparison among the different wells. The petrophysical characteristics of the Kareem Formation reflect the ability of this rock unit to generate, store and produce hydrocarbons. The shale content varies from 6 to 75, effective porosity ranges from 2 to 17% and hydrocarbon saturation ranges from 0-80%, which reflect good reservoir characterization. As a recommendation, more exploration activities are needed to be done along the Belayim Land Field especially across the western part of the area under investigation. | ||||
