We apply Full Waveform Inversion (FWI) to a Narrow Azimuth (NAZ) towed streamer data acquired over the Samson Dome region in the Barents Sea which has complex structural geology. This case study demonstrates the improvement in seismic image quality resulting from dramatically increasing the wavenumber content in the velocity field using FWI. The FWI result shows a spatial consistency that was unexpected from a standard 3D NAZ dataset. It also demonstrates the potential use of FWI velocity models in geological interpretation and shallow geohazard detection, even though in this implementation the FWI is effectively solving a combination of velocity, anisotropy and density, rather than just P-wave velocity.
