Abstract

Two migration procedures are described which allow a wide range of steep-dip seismic boundaries to be imaged. The first procedure is based on using duplex waves that suffer mode conversion when passing through seismic heterogeneities. Thus, these are transmitted converted waves, which are still not involved in surface seismic exploration. The second procedure is based on interferometric migration both compressional and converted wave fields, continued downward to the points of mode conversion. For imaging, this procedure uses primary reflected compressional and converted waves, as well as duplex reflected and transmitted compressional and converted waves. This assembly of waves allows us to obtain a migration procedure with, practically, no limitations on the angle of inclination of the seismic boundaries. Examples showing both migrations on synthetic data are provided.
