Imaging in deep-water environments poses a specific set of challenges, both in data preconditioning and velocity model building. These challenges include scattered, complex 3D multiples, aliased noise, and low-velocity shallow anomalies associated wi

Conventional 2 nd and 4 th order RMO picking of moveout on CRP gathers for a complex sea-floor canyon area, offshore Sri Lanka, failed to capture the short wavelength velocity variation associated with the buried canyons, thus limiting the ability of

Offshore Sri Lanka, basaltic flows and other intrusive bodies (sills and dykes) hamper efforts to image deeper structures. In this study, we demonstrate the ability of hi-resolution hybrid gridded tomography to resolve the internal structure of an ex
