Paper Summary
This paper presents a case study of a 3D marine streamer seismic acquisition using an ultra-wide-tow penta source set-up to improve trace density and near offset coverage without compromising acquisition efficiency. The survey was shot in 2020 in the Barents Sea where the water depth is approximately between 300 m and 400 m. The total source separation in crossline direction was 315 m. The acquisition and processing grid was 6.25 m x 6.25 m and the processing was carried out at 2 ms temporal sampling. The high number of sources introduces additional blended signals which were simultaneously separated using an iterative deblending method. We then demonstrate the effectiveness of a standard demultiple workflow which benefited from the rich near offset distribution and the early out migrated images show high resolution quality in the very near surface.
