The of inverse beam stack multiple suppression method has shown cleaner results than the results of the PRT method on the same synthetic data examples. As such, the beam stack method can be attractive method when the PRT method is not optimal. The beam stack method is especially attractive in situations in which prestack amplitudes are important. The beam stack method performs well in the presence of very strong multiples, in the presence of non-hyperbolic moveout and in cases of significant AVO on primaries or multiples. The speed is comparable to the PRT method. Unfortunately the near offset remnant multiple energy is a problem for the beam stack method. The near offset energy may be handled using predictive deconvolution. Another possible shortcoming is that the beam stack method may be sensitive to primary events in NMO-corrected gathers that are not completely flat.
