AVO Processing - Myths and Reality

N-14 AVO PROCESSING – MYTHS AND REALITY Summary 1 AVO processing is meant to make the input data compatible with Shuey’s equation. This task is extremely difficult due to the overly simplistic formulation of the problem compared with the complexity of the real physical experiment. Fortunately the advent of elastic impedance has made it possible to relax some of the processing requirements. Some major concerns (such as amplitude balancing and NMO-stretching) have become almost irrelevant while others that were often overlooked (such as residual-NMO and multiples) have become critical. Introduction Although preserved amplitude processing is a clear requirement for AVO
