H012 Surface Seismic Imaging with VSP Green’s Functions S. Brandsberg-Dahl* (BP America) X. Xiao (University of Utah) & B. Hornby (BP America) SUMMARY We present a method for imaging surface seismic data that does not depend on a background velocity model. Instead of computing Green’s functions in a background velocity model we use direct measurements from VSP data as Green’s functions for the migration. Although the method is strictly only valid for v(z) media we show that mild lateral variations can be handled. The proposed method allows us to image/migrate surface seismic data from areas with layered geology without having
