Migration for zero-offset multiple reflections

It is interesting that cross-correlation between primary reflections and multiple reflections can provide a real zero-offset dataset, which can be processed by poststack migration. Figure [*] displays the poststack migration of the zero-offset dataset of pseudo-primary data. The migration result is noisy because only one offset of the data has been used while usually all offsets of the data are stacked after NMO in poststack migration. But we can still interpret the subsurface structure from the image, including the top and bottom of the salt, and the flat reflector below the salt.
