Moving Toward Palinspastic Reconstruction of Velocity Models in Prestack Depth Migration

In order to produce an accurate depth migration of a seismic line, one needs an accurate velocity model. This model should reflect the lithology and lithostatic load that the rocks have experienced through burial and deformation. If we understand the geometry of these rocks, and their behaviour upon deformation, we can produce a more accurate velocity model. Performing palinspastic restoration of a depth-migrated seismic line can be used to assess the geologic validity of the velocity models and can lead to improvements in these models, particularly in the fine-scale velocity structure of exploration targets.
