Various far-offset marine acquisition geometries have been deemed as promising for alleviating imaging difficulties in the deepwater Gulf of Mexico (GOM). In this case study from the GOM we explore the benefits of far offsets using ocean bottom node (OBN) data with acquisition offsets up to 25 km, and investigate the untapped potential of extremely far offsets of up to 50 km. Using offsets between 12 km and 25 km is not straightforward but these offsets can significantly improve the subsalt images and were valuable for building the salt model in this study. Although their usefulness may be limited in salt model building, we observed imaging benefits from extremely far offsets up to 50 km.
