It is well known that a complex near surface—encountered in areas such as desert, mountainous, and glacial till environments—can significantly distort primary reflections from deeper horizons of interest. This has been and remains a major problem in seismic data processing.

One way to address this situation is via data processing methods that can be classified under the general term “redatuming” techniques. Conventional redatuming methods involve applications of static time shifts to the input traces. These time shifts (commonly known as statics) can be applied prestack and/or poststack to compensate for the effects of the near surface. The key assumption inherent...
