In practice, reverberations often are generated by a more complicated physical situation than the one we have described, so the simple dereverberation operator a given above is not adequate. The received seismic trace is made up of many reflections, each represented by its reverberation train. All of these reverberation signals overlap to various degrees. Thus, usually it is not feasible to obtain a direct measurement of the shape of any individual reverberation train. In such a situation, the method of predictive deconvolution can be used to attenuate the reverberations and thus to better delineate the deep reflections, which we want to see.
