Predicting sand distribution and reservoir presence is a major exploration risk in the Nile Delta offshore Egypt. However, integrating state-of-the-art technologies including 3-D seismic reflection surveys, seismic attributes, amplitude extractions, and coherency techniques can reduce this risk through recognition and more accurate mapping of submarine valleys and channel complexes. In addition, identification of sediment input points and pathways may result in more accurate interpretations of sand distribution patterns.

Seismic profiles from the area of interest indicate that Upper Miocene (Messinian) evaporites created a series of bright reflectors that are overlain by a Lower Pliocene transgressive sequence which, based on well...
