Abstract
A method is described for improving subsalt seismic imaging using wavefield redatuming. The method redatums the source wavefield and receiver wavefield to the salt surface. It cross-correlates the redatumed wavefields and uses the time cross-correlations to update the salt surface. The method may be executed by a computer system.
