Addressing imaging challenges in the Viking Graben with multi-azimuth acquisition, longer offsets, and wide-tow sources

The Viking Graben is a mature exploration area on the Norwegian Continental Shelf that still suffers from illumination and resolution challenges that reprocessing alone cannot solve. In the following case study we demonstrate how those challenges were addressed by a novel towed streamer acquisition project in 2019. The multi azimuth acquisition solution featured latest advances in towed streamer technology including variable streamer lengths and wide tow sources. The survey delivered improved near-offset sampling, higher trace density, denser spatial sampling, and larger azimuthal coverage in a cost and time effective manner. Imaging results from the ongoing processing project are presented.
