Depositional Environment and Storage Capacity of Eocene Carbonate Rocks, South Western Sinai, Egypt

The main objective of the present study is to shed light on the lithostratigraphy, microfacies association, depositional environment, and the petrophysical characteristics of the Eocene carbonate rocks in southwestern Sinai, Egypt. The study area is represented by two examined sections, namely Wadi Tayiba and Wadi Feiran (from older to younger): Thebes, (Samalute equivalent Darat), Khaboba and Tanka. In this study, five microfacies were identified. These microfacies are: pellitiferous micrite, micrite, foraminiferal biomicrite, argillaceous micrite, and fossiliferous micrite. These are deposited in a platform and an open marine occurrence on the inner ramp. The obtained petrophysical results show that the Darat Formation at the Wadi Tayiba area and the Thebes Formation at the Wadi Feiran area possess the best storage capacity of the Eocene carbonate rocks in the studied area.
