Multidimensional Filtering of Irregularly Sampled Seismic Data

A037 Z-99 MULTIDIMENSIONAL FILTERING OF IRREGULARLY SAMPLED SEISMIC DATA Abstract 1 In this paper we introduce a new technique for multidimensional filtering of irregularly sampled seismic data. In this context filtering may be used for coherent noise and interference attenuation as well as the generation of seismic images. The filtering operation consists of the convolution of the filter operator with the seismic data. The filter operator is usually computed on a regular grid (rectangular or hexagonal) that corresponds to the nominal sampling of the seismic data. Unfortunately in the physical world the seismic data are often sampled at irregular spatial
