Post-Stack Kirchhoff Depth De-Migration Method for Tilted Transverse Isotropic (TTI) and Heterogeneous Media Based on Ray Tracing on Migrated Data
Post-Stack Kirchhoff Depth De-Migration Method for Tilted Transverse Isotropic (TTI) and Heterogeneous Media Based on Ray Tracing on Migrated Data
The present invention is related to a specific de-migration method based on ray tracing algorithms characterized in that the interpolation procedure involved in the computation of the travel time required by the de-migration is being modified. The interpolation according to the invention obtains an accurate travel time for those rays departing from sources being interpolated.
