Abstract

This invention is a method of attenuating multiples in seismic data, particularly three-dimensional seismic data in which seafloor roughness is present. The method relies on an efficient ray-tracing procedure to determine traveltimes for each multiple. The characteristics of the seismic data are used to estimate the waveform of the multiple to be attenuated. The traveltime and the estimated waveform are then used to attenuate the multiple from the original data. The method can be employed both for water-bottom multiples and for source (36) and receiver (26) pegleg multiples.
