Simultaneous Pre- and Post-NMO Deconvolution , by Jon F. Claerbout

Wave theory justifies both pre- and post-NMO deconvolution, but the filters should be estimated simultaneously, not sequentially. A conjugate gradient procedure estimates the two filters simultaneously. The method also handles spherical divergence independently from statistical weighting. Test cases demonstrate the expected interaction between NMO and deconvolution. The tests were inadequate to establish that simultaneous estimation is superior to sequential estimation.
