Interpolation of near offset seismic trace using surface-related multiples

A seismic trace interpolation method was presented based on raw prestack common shot gather with surface-related multiples. By using the method, we firstly generate the pseudo-primaries by the cross correlation of original seismic data to extract the seismic information included in the multiples, instead of nearby traces information conversion or rebuilding missing seismic data by extrapolation. The pseudo-traces is corrected by using Least-squares Matching Filter (LMF) and RMS amplitude correction in slipping time-space window for filling the trace gaps, and then the corrected traces is used for missing traces interpolation rebuilding. The method needs no extraction of primaries and multiples are easily realized. The feasibility and validity of this method is proved by model test and practical application.
