Summary:
We utilized interferometric datuming to convert VSP first-order surface-related multiples into virtual surface-seismic primary reflections. These reflections are subsequently imaged using a Kirchhoff-based migration to obtain representative subsurface structures. Tests on both synthetic and field datasets demonstrate the ability of imaging with VSP multiples to extend the spatial resolution of the migrated images. We concluded that imaging with VSP multiples could potentially provide a wider subsurface illumination compared with conventional imaging with VSP primaries.
