Near surface variations not only create time delays but can create a more complicated frequency dependent phase distortion. The estimation of surface-consistent residual statics can be generalized to the phase, with the same attempt to maximize the stack power. The method presented in this paper, based on cross-spectral analysis, allows performing surface consistent residual phase corrections. This approach has the advantages to avoid the phase unwrapping and to use the full phase spectrum. Used after a first pass of surface-consistent residual statics or not, the proposed algorithm shows very encouraging results.
