| Abstract | ||
| A package of 2D reflection seismic lines of good quality set is ordinarily interpreted to disclose the structure controls of the Shorouk field, NorthWestern Desert of Egypt. The geological and geophysical information are helped to facilitate creating a number of maps and cross sections that clarify the tectonic fabric. The study focuses attention on tops of the Lower and Upper Bahariya members which act as major hydrocarbon reservoirs in Shushan basin. The seismic reflection interpretation aims to review and bring insight into the basin architecture, which may increase the chances for developing and/or exploring the entrapments. The work steps involve identification, picking and correlation of reflectors, closing loops, fault detection, constructing geoseismic cross sections, time, and depth structural maps. The reservoir quality was confirmed through constructing the correlation charts between wells. The results indicate that the Shorouk field lies on a fault-bounded high feature. The structure at Bahariya Formation is affected by an anticlinal horst, cut across the central area in the WNW-direction, and bounded by normal faults down-step to the north and south. These bounding faults seem to be inherited from older ones along lines of weakness and grow up into the overburdens. The seismic lines investigation gives no evidence to support the presence of any salt ridges or magmatic flows into fractures. Tieing well data with seismic events revealed that the seismic depths are deeper than the actual, with ~100m static shift. The dip-reversals along flanks of the central closures are the most potential traps at Bahariya Formation. | ||
