Abstract

For VSP data, interferometric migration of free-surface multiples has two significant advantages over standard VSP migration: 1). a significantly larger imaging area than that of conventional migration of VSP primaries, and 2). less sensitivity to velocity and static errors than conventional migration of VSP multiples. In this report we validate these claims by applying wave-equation interferometric migration to 3D VSP data. Results show that interferometric migration can produce an image volume that is comparable to that of a small 3D surface seismic survey around the well, but at a much reduced processing and acquisition cost. This may suggest that 3D interferometric migration of VSP multiples can be a cost effective 4D monitoring tool for some oil fields.
