| Title of Invention | METHOD FOR SEISMIC MIGRATION USING EXPLICIT DEPTH EXTRAPOLATION OPERATORS WITH DYNAMICALLY VARIABLE OPERATOR LENGTH |
|---|---|
| Abstract | Explicit depth extrapolation operators are constructed with variable operator lengths depending on maximum dip angle, accuracy condition, and wave number. Operator tables are then constructed using the explicit depth extrapolation operators. In a further embodiment, depth migration is performed using the explicit depth extrapolation operators from the operator tables. |
