摘要：Near-offset and far-offset seismic data volumes are time-aligned by firstselecting a plurality of time shifts. The near-offset and far-offset seismic data volumes
are cross-correlated at the plurality of time shifts. An initial time-shift volume and amaximum correlation volume are created from the maximal cross-correlations at theplurality of time shifts. Areas of high time shift from the initial time-shift volume andareas of low cross-correlation from the maximum correlation volume are determined.The determined areas of high time shift and low cross-correlation are filtered from theinitial time-shift volume, generating a filtered time-shift volume. The filtered time-shiftvolume is applied to the far-offset seismic volume to generate a time-aligned far-offsetvolume.
