Seismic structural models at Shukheir Bay Field, Gulf of Suez, Egypt

Bulletin of the Faculty of Science F, Geology

Seismic structural models at Shukheir Bay Field, Gulf of Suez, Egypt

To help understanding of the Shukheir Bay Field potential, reservoir delineation and lithology recognition, together with hydrocarbon identification, were integrated in the present study that was achieved incorporating all available geological and geophysical data. The geological and geophysical data revealed the structural architecture of the studied oilfield and evaluated the prospective areas worth to drill or to farm out. Well data of the surrounding fields were incorporated to place Shukheir Bay Field in its proper regional setting. Shukheir Bay field was found to be in the northeast dip province similar to the surrounding onshore fields (Ayun, Umm El Yusr and Kheir) and the offshore (July and Ramadan) fields. There is a dominant southwest dip regime in Shukheir Bay field, which is probably due to drag on faults. The Clysmic westerly dipping faults are the dominant structural trend of the field. The easterly dipping faults are the minor faults. The complex trace analysis of the seismic data was very useful to identify the reservoirs and to delineate accurately the structure and stratigraphy of the study area. Also, the actual and real reflection coefficient and the hydrocarbon indicators characterizing the study area were calculated from the true amplitude seismic data. The high accurate lithology identification expressed in interval velocity and density profiling was the yield of the inversion of seismic data. All data including geological, petrophysical and geophysical information were integrated to identify an accurate and descriptive structural model for the field. The geometrical distribution of the field reservoirs and the resolution of the stratigraphical units were achieved in this study. The Kareem and Rudeis sands, which are widely distributed in the area, are representing the main reservoirs in the Shukheir Bay field. Their distribution seems to be strongly affected by the pre-existing topography that, occurred after the Rudeis unconformity.
