POST-STACK KIRCHHOFF DEPTH DE-MIGRATION METHOD FOR TILTED TRANSVERSE ISOTROPIC (TTI) AND HETEROGENEOUS MEDIA BASED ON RAY TRACING ON MIGRATED DATA

摘要

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.
