Integrated Prestack Depth Migration of VSP and Surface Seismic Data

M-31 INTEGRATED PRESTACK DEPTH MIGRATION OF VSP AND SURFACE SEISMIC DATA Summary 1 A new prestack depth migration algorithm has been developed for the integrated depth imaging of Vertical Seismic Profile (VSP) and surface seismic data. The algorithm which is Kirchhoff-based includes anisotropic velocities and can also be applied to depth migration of converted waves and multimodes. Results from the depth imaging of a numerical model data set from a complex structural model shows that the integrated imaging of VSP and surface seismic data yields a result that is superior to those obtained from the migration of either data set
