Reservoir Characterization of the Middle Jurassic Lower Safa Member in the West Kanayes Fields, North Western Desert, Egypt.

Abstract

The objective of this study is to evaluate Lower Safa Member in West Kanayes fields, located in Western Desert of Egypt.Zones with favorable log responses such as gamma ray readings, positive resistivity separation,and neutron-density separation indicative of sandstone were selected for further analysis.Key petrophysical parameters,including shale content,effective porosity,and water saturation,were computed using established equations.The results indicate that the WKAN D-1X well contains one promising interval characterized by the average effective porosity 7.5% and higher hydrocarbon saturation of average value of nearly 64% and the net pay thickness 3 ft.In contrast,the WKAN E-1X well contains one promising interval characterized by high effective porosity with averaging 8.1% and higher hydrocarbon saturation of average value 85%and the net pay thickness 3 ft. WKAN F-1X well identified one promising zone,with effective porosity 7.3%and the hydrocarbon saturation of average value 59.7%and the net pay thickness 4 ft. The WKAN I-1X well contains eight promising intervals characterized by high effective porosity with averaging 8.9%and higher hydrocarbon saturation of average value 66.6%and the net pay thickness 58 ft.Similarly, the WKAN N-1X well showed four zones with effective porosity 10.3%and the hydrocarbon saturation of average value 65.3%and the net pay thickness 44 ft.Through our study,we found that the Lower Safa Member composed of a mixture of Siltstone,Sandstone,Shale,and occasional Limestone and coal streaks,according to lithological identification.Overall,the Lower Safa Member exhibits potential hydrocarbon-bearing zones with varying degrees of reservoir quality,influenced by shale content and porosity levels.This evaluation provides a foundation for further exploration and development in the West Kanayes field
