Patent ID: 8103452

Claim:
Method for processing with a processor seismic data comprising a collection of seismic traces with different offsets, comprising the steps of: a) breaking up a first trace representing physical events occurring in a subsoil of the collection of seismic traces into a series of trace segments according to a predetermined segmentation interval; b) defining a series of expansion coefficients, each expansion coefficient being assigned to a segment of the first trace; c) applying each expansion coefficient of the series of expansion coefficients to their assigned segments of the first trace to create an expanded first trace; d) comparing the expanded first trace with a second trace from the collection of seismic traces to evaluate their similarity; e) repeating steps b), c), and d) with a new series of expansion coefficients, and f) determining with the processor an optimum series of expansion coefficients that maximizes the similarity between the first expanded trace and the second trace in order to obtain a corrected first trace of seismic data representing physical events occurring in the subsoil.
