ABSTRACT:
Seismic data are passed through a preselected number of migration stages. During each stage, data are migrated a plurality of times, where the migration-velocity function is a minor fraction of the velocity required to fully migrate the data in a single stage. The cascaded migration migrates data having steeply-dipping events with greater accuracy and with less noise or artifacts than does a single-stage migration.
