Future research

Two promising potential future research projects would be to demonstrate datuming with field data for applications to land data static corrections, and for migration in complex velocity areas. In deep marine seismic surveys, the removal of the water bottom multiples has long been a tricky problem. A likely solution is to datum all the common-shot and common-receiver gathers to a planar datum just above the water bottom, so that water bottom multiple travel-time period is short; conventional predictive deconvolution (Peacock and Treital, 1979) should work well, as in shallow water seismic surveys. Finite-difference datuming also has potential for applications in estimating background velocity by layer stripping procedures.
