PSDM provides very good imaging results but is often not optimal for time to depth conversion. PSDM model uncertainties quantification and calibration to well data may benefit from geostatistics. Complexity in the geological structures (presence of a salt dome for example) can be very challenging for spatializing data and requires therefore the use of innovative geostatistical techniques such as kriging with a fast marching algorithm.
