Gas-generative potential for the post-Messinian megasequence of Nile Delta Basin: a case study of Tao Field, North Sinai Concession, Egypt

Abstract The main aim of the article is to evaluate gas potentiality for post-Messinian megasequence in TAO Field, North Sinai Concession, offshore Nile Delta Basin. detailed petrophysical analysis three deviated wells study area (Tao-3 ST1 Well, Tao-5 STA Well and Tao-7 Well) revealed that Pliocene Kafr El-Sheikh Formation includes eleven gas-bearing zones. These zones were named: A, B, C Tao-3 D, E, F Well. In interesting are named G, H, I, J K. All these sandy intervals relatively shallow depth differ thickness between 4 56 m. characterized by shale volume (10%), total porosity (30–40%), effective (30–35%), saturation (50–90%), high permeability low water. seismic data displayed listric faults associated rollover folds have an important role forming structural traps examined Tao Field its surroundings. This work success rate discovering new prospects within Pliocene–Pleistocene succession at Concession very high.
