Abstract

Summary

Surface-related multiples widely exist in marine seismic data and contain valuable subsurface information. Migration of multiples has higher vertical resolution and more balanced illumination compared to imaging with primaries, however, there can be strong interference from multiples with different orders or primaries when high order multiples are migrated. In this paper, borrowing the idea from SRME, we developed the method to separate different order surface-related multiples and then proposed one-way wave-equation migration (OWM) of different order multiples, in which only primaries are forward propagated crosscorrelation with backward propagated certain order multiple to avoid artifacts. Our approach was applied to deep marine field data. OWM of first order and second order multiples have more balanced illumination and higher dominant frequency which proved that OWM of different order surface-related multiples is a favorable supplementary to migration of primaries.
