A dip-based correction is calculated per trace and per sample for differences in azimuth, common midpoint coordinates, and offset between the best fitting trace and the desired trace. The dip-based correction is applied to the best fitting trace to reconstruct the desired trace for 3D surface-related multiple prediction.2/3 (20 Determine best fitting trace in seismic data for desired trace to be reconstructed 1 1-21 Calculate dip-based correction for differences in azimuth, CMP coordinates, and offset between best fitting and desired traces r22 Apply dip-based correction to best fitting trace to reconstruct desired trace for 3D surface-related multiple prediction FIG. 2
