Abstract
Methods and systems for ghost compensation of seismic data in conjunction with Kirchhoff migration are described. Input traces are deghosted by applying a deghost operator thereto across a range of ray parameters, which ray parameters are associated with the Kirchhoff migration. The deghosted traces are buffered and then selected for use in the mapping stage of Kirchhoff migration.
