Abstract
A method is for use in seismic data processing includes improving the continuity of the primary events in an original seismic dataset to create a continuous, seismic dataset; predicting at least the first order multiples of the original seismic dataset from the continuous seismic dataset; deterministically matching the predicted multiples and one of the original seismic dataset or the continuous seismic dataset; and taking the difference between the matched datasets. In other aspects, an apparatus may include a computer programmed to perform to such a method and by which the seismic data may be processed. The apparatus may also include a program storage medium encoded with instructions that, when executed by a computing device, will perform the method. The data upon which the method operates may be acquired in either a land or marine survey and may be two-dimensional, three-dimensional, or four-dimensional.
