Abstract

Marine seismic data acquired over seafloors with rough topography are characterized by the presence of complicated multiple energy patterns. We present a model-based surface-related multiple modelling technique free from any constraint relating to the shot position and distribution. This technique may require streamer interpolation/extrapolation, but does not require any sail lines reconstructions. We are comparing results with conventional and dense acquisition geometries on a Norwegian Sea dataset. The sail lines were shot with 50% overlap for testing of 3D SRME techniques with special attention to the acquisition geometry. The results achieved with nominal and dense acquisition geometries are equivalent, as a consequence the proposed approach does not require dense cross sail line acquisition geometries neither dense cross sail line data reconstruction.
