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 travel-times for each multiple. The characteristics of the seismic data are used to estimate the waveform of the multiple to be attenuated. The travel-time 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 and receiver pegleg multiples.
