Modern 3D land seismic data, acquired by small field arrays or single sensors, require some type of prestack enhancement based on local stacking to accumulate large enough signals for estimating time processing parameters. We demonstrate that the cross-spread domain provides the most suitable 2D domain with regular and dense trace distribution. Evaluating residual moveout after normal moveout (NMO) correction enables local estimation of reflection moveout, whereas summation along moveout in the cross-spread domain benefits from uniform trace density within the enhancement ensembles irrespective of offset, azimuth or fold. This is demonstrated on field data examples. Mixing of different azimuths is naturally avoided for anisotropy friendly processing.
