| Abstract | ||
| Slope channels are regarded currently as one of the most important reservoirs in several localities around the world as Gulf of Mexico (USA), Offshore West Africa, Offshore Indonesia, Offshore Nile Delta (Egypt), etc. Most of these slope channels reservoirs mainly belong to Cenozoic epoch. Within the Nile Delta gas province, reservoirs are dominated by Pliocene slope channel systems and understanding the geometry and distribution of its component sand bodies is very important. It is argued that when deepwater reservoir architecture is understood, this can be used to improve deepwater reservoir production performance. The objectives of the current study are to predict sand distribution and reservoir presence and the main targets are to follow the Pliocene channel prospect and evaluate its characteristic. Accurate petrophysical evaluation of deep water channels composed of thin bedded sand-shale sequences is crucial in the economic decision to explore, develop and produce these reservoirs. Visualization of the geometry of the Pliocene channel complex is based on 3D multiazimuth (MAZ) seismic data. The high resolution seismic, combined with log observations, provide spectacular insights into the gross seismic architecture and the internal geometry of the Pliocene channel complex. In the studied area, the Pliocene channel structure is complex in terms of faults distribution with more faults in the southern half of the structure. It consists of multi-sand package in the northern part of the channel with high net to gross (NTG) while the southern part of the channel exhibits only one sand package has low net to gross (NTG). | ||
