ABSTRACT
The study area is located in the eastern offshore area of the Nile Delta of Egypt, between Long. 31° 84', 32° 44', and Lat. 31° 52', 31°30', approximately. The main gas fields of the study are Port Fouad and Wakar . This work aims to define hydrocarbon potentiality and its relation to geological processes through time, using geological and geochemical models. This study concerns six wells, namely, Port Fouad Marine-1,-2,-3,-4, Darfeel-1, Wakar-1 and -2 to evaluate the potential un-tested bypassed zones. The drilled stratigraphic section of the area ranges in age from Miocene to Pleistocene. The interpreted seismic lines, structure contour maps, isopach and isolith map illustrate that the upper surface of each of Kafr El Sheikh and Wakar formations shows NW-SE trending gentle anticlinal dome-like structures. The petrophysical study includes the sandstone layers in both Wakar and Kafr El Sheikh Formations. The porosity values indicate good to very good reservoir properties. Results also show that the overall area is characterized by source rocks of poor to fair hydrocarbon potentiality. The source rocks of Kafr El Sheikh, Wakar and Sidi Salem formations have generated hydrocarbons since the Late Miocene and Pliocene. The hydrocarbon migration pathways in the area are suggested to be from north, northwest and northeast to south, southeast and southwest directions following the up-dip direction of strata. The vertical movement through the fault planes is also suggested as different types of gas (dry and wet) in shallow reservoirs of Kafr El sheikh and Wakar are present. New hydrocarbon discoveries are expected with some structural up-thrown fault blocks and stratigraphic sand bodies (lenses and facies changes).
