Abstract

Marine seismic data acquired over sea floors made of submarine canyons are characterized by the presence of extremely complicated patterns in the shape of the reflected multiple energy. Despite the fact that data-driven SRME techniques do not require any a priori knowledge of the subsurface (reflectivity, structures and velocities), it is sometimes difficult in 3D to perform the reconstruction of the missing data or the missing multiple contributions needed when applying this technique, as the method theoretically requires a shot location at each receiver location. In the following instead, we present a model-based surface-related multiple modeling technique (SRMM), which is free from any constraint relating to shot position (including OBC) and distribution, which was applied on marine seismic data acquired offshore Brazil over a series of deep submarine canyons.
