Wave equation datuming is the upward or downward continuation of seismic time data when the purpose is to redefine the reference surface on which the sources and receivers appear to be located. This technique, differs from conventional datuming methods in causing seismic reflection to move laterally as well as vertically in response to observed time dips. In the most interesting applications of the technique, the redefined reference surface is an actual geological interface having an irregular topography and a large velocity contrast. Wave equation datuming as a data-correction method can remove the deleterious effect such an interface has on seismic reflections originating below it. The method is also applicable to seismic modeling.
