Abstract:ABSTRACT. We present a migration method for plane wave source data based on the Kirchhoff integral. Plane wave migration has been employed to increase the efficiency of the wavefield extrapolation. Point source records are synthesized into a plane wave and the resulting plane wave data can be migrated using the same scheme as the one for conventional shot-record migration. Plane wave migration reduces the migration computation time, because the extrapolation does not need to be done for all the individual shot… Show more
