The proposed acquisition methodology features variable separations between adjacent sources and between adjacent streamers and builds on recent advances achieved by the seismic industry in towing the sources wide. This methodology results in better near offset coverage while improving survey efficiency, up to approximately 28% when compared to conventional configurations. A theoretical case study is presented to explain how to design this new towing concept and demonstrate the expected gains when compared to similar configurations.", }
