Abstract
This invention relates to a method for processing seismic data comprising a collection of seismic traces with different offsets, comprising the steps of: a) breaking up one or several first trace(s) of the collection of seismic traces into a series of trace segment's according to a predetermined segmentation interval; b) defining a series of expansion coefficients, each expansion coefficient being associated with a segment of the first trace or traces; c) applying the associated expansion coefficient to each segment of the first trace or traces; d) comparing the first trace or traces thus expanded with a second trace from the collection of seismic traces to evaluate their similarity; e) repeating steps b), and d) with a new series of expansion coefficients, f) determining an optimum series of expansion coefficients that maximizes the similarity between the first expanded trace and the second trace in order to obtain one or several corrected first trace(s).
