The Northeast Mediterranean Deepwater Area (41 500 km2) was awarded to Shell Egypt in July 1998. Operations started on 1 February 1999 to acquire a 7000-km, 2-D (6-km cable, 8 s, 120-fold) seismic survey. Key pre-1999 data included a 1500-km 2-D seismic (1973 vintage). In December 1999 Exxon Exploration and Production, Egypt acquired a 25% interest in the concession.
The concession is exceptional for its size (Figure 1) and its location in front of a major productive delta. The newly acquired 2-D seismic have enabled mapping of the geology of the whole concession for the first time. This mapping shows four distinct geologic domains, each with unique play characteristics. Of these, only the Nile Delta gas/condensate Pliocene and Miocene Platform domain has been tested. No wells have been drilled in the area, but direct hydrocarbon indicators on seismic attest to a high probability of charge. The nearest calibration points are in the southern West Delta Deep Concession where the Scarab and Saffron gas accumulations have been discovered. Shallow boreholes of the Deep Sea Drilling Project (DSDP Leg 160) provide data in the area of the Erastothenes Seamount and to the west of Cyprus (Figure 2).
During seismic acquisition, 10 000 km of shipboard gravity data were acquired. These data have been integrated with available satellite gravity data. In addition, 30 750 km of high-resolution aeromagnetic data …
