Resolution enhancement with deconvolution after migration

Deconvolution is a process that is normally applied to seismic data before migration to enhance the resolution. We propose that deconvolution should also be applied to the data after a poststack or a prestack migration. We address the objections to this process, then present arguments for its use. The deconvolution process should be applied as a multidimensional process to the complete data. However, a typical trace process is usually sufficient to provide a significant enhancement in the resolution after migration. Two data examples are provided that show significant improvement in the resolution of the data by use of a simple spiking deconvolution that was applied to each trace after migration.
