Migration and demigration deblending in receiver domain
Ziguang Su, Daniel O. Trad
In some important cases, for example, ocean bottom node surveys(OBN), seismic acquisitions have more sources than receivers. This brings the need to develop processing and inversion techniques that work more efficiently in the receiver domain. After exchanging source and receiver location, receiver domain Reverse Time Migration (RTM) can save significant computation time compared with shot domain RTM. This problem is also interesting because some deblending techniques exploit incoherence in the receiver domain created by time delays in the shot domain to separate simultaneous sources. In this report, we investigate receiver domain RTM for both migration of regular surveys and its possible use for the deblending of simultaneous sources.
