ABSTRACT:

Tortonian and Serravallian potential reservoirs represent the main goal for hydrocarbon exploration in the north east province of the Nile Delta. In the present study such clastic reservoirs have been divided into vertically stacked lithologic cycles on basis of detailed biostratigraphic (foraminiferal and calcareous nanno plankton) analysis and electrofacies evaluation. The detailed environmental investigation of the resulted lithologic cycles revealed their deposition in deep marine zone as slope channels. The channels axes trend and the paleo-current direction have been detected from dipmeter patterns, 3D seismic lines interpretation and lithofacies evaluation. The structural architecture of the study area and its evolution from the early Miocene till the present day have been reviewed and a paleotectonic image for the north east province of the Nile Delta has been suggested in the present work. The tectonic evolution within Temsah, Port Fouad Marine and Wakar gas fields played an important role in the Serravallian-Tortonian reservoir distribution, which controlled the channels and hence the sediments fairway. It seems that the two main dominating fault trends (NW & NNE) were influencing the transport direction and the channel distribution during that period of time. The proposed depostional model opens optimistic prediction for further basin ward exploration phases
