Migrating composite seismic response data to produce a representation of a seismic volume

Image Number 4 for United States Patent #7599798.

A subterranean structure is characterized using composite seismic response data received from a plurality of sources. Phase encoding is applied to the data in which phase shifts are selected based on frequency variation of noise terms. The phase-encoded data is then migrated and a representation of the subterranean structure is produced according to the migrating.
