Using Least-Squares to Reduce Migration Noise Richard Leggott (CGGVeritas) Richard Wombell (CGGVeritas) Tony Noss (CGGVeritas) Graham Conroy (CGG Veritas) and Gareth Williams (CGGVeritas) SUMMARY____________________________________________________________ Seismic data should be migrated before analysis and interpretation. However the process of migration is often a source of noise; this is especially true of onshore seismic data where an “acquisition footprint” is a common problem. The origin of this migration noise lies in the difficulty of computing an accurate migration operator. If simplifying assumptions are used such as regular acquisition geometry then the computation of the migration operator becomes practical. Such assumptions are almost universal
