Neptune Energy has licensed a concession as operator in the North West El Amal in the Gulf of Suez, Egypt (Figure 1). The seismic data available over the block was acquired in 1992 with a narrow azimuth 5 x 3km towed streamer geometry (NAZ), suitable for the shallow target at that time. One of the targets of the project was Nubia sandstones in the deep faulted blocks due to the Red Sea opening at a depth of 4 to 5 km. In order to image these faults, a new set of data was required, with full azimuth for deep target illumination and long offsets to leverage the latest depth imaging technologies, most particularly full waveform inversion (FWI). The presence of surface obstructions such as production platforms, made wide azimuth (WAZ) towed streamer acquisition impossible. Seabed nodes offered the obvious solution. To ensure an optimum illumination of the target and yet economically viable project, it was decided to test and select the optimum acquisition parameters (receiver, shot templates) with a survey design and modelling (SD&M) exercise and compare the results at the target horizons with the illumination generated by the NAZ streamer acquisition of 1992.
