Abstract

The turbidite sands of the Nile Delta Plio-Pleistocene section have been demonstrated to be a good quality reservoir within the Egyption Mediterranean Gas Province. Exploration has been based in the last decades on the definition of clear direct hydrocarbon indicators (DHI), as the bright spots, flat spots, amplitude shut-offs, polarity reversals,…. etc.  In this paper, the seismic attributes technique; such as the root mean square (RMS) amplitude, reflection intensity, instantaneous frequency and Instantaneous phase are applied to the 2D seismic sections, in combination with the well log data, in addition to core data, to delineate the stratigraphic features, such as channels in the Lower Pliocene deposits and to investigate new potential in the Upper Pliocene surrounding North Idku 4-x well. Thus, based on the combined investigation of the geologic cores, geophysical well-logs and seismic attributes two channels and two possible leads are delineated and confirmed in the study area.
