REGULARISATION OF IRREGULARLY SAMPLED SEISMIC DATA

摘要

There is provided a method of spatially shifting seismic signals acquired through a seismic survey using the steps of identifying within the signals a set of N actual locations of seismic receivers and corresponding N seismic signals received by the set of seismic receivers; identifying a set of N' d esired locations of seismic receivers; and determining a set of N' signal va lues at said N' desired locations by evaluating for each of said N' signal v alues a weighted sum of the N seismic signals, wherein the weights are at le ast partly determined by the relative distance between pairs of locations se lected from said set of N actual locations of seismic receivers.
