Abstract

We present and discuss some improved results with a recently developed method for multiple suppression in the nearoffset<br>domain by using warping filters. The main steps of the application of the method are (a) simulation of multiples by<br>means of Kirchhoff-type summations applied to a common near-offset section; (b) application of an adaptive filter to<br>adjust simulated multiples, and (c) subtraction from the original data. Our approach consists in deforming simulated<br>multiples in order to match the geometry of observed multiples. A mesh warping specification was chosen due to its<br>simplicity, efficiency, and robustness. The warping technique has been successfully applied to correct strong<br>deformations present on simulated multiples in shallow-water data.
