We presented a joint tomography flow for OBN and streamer WAZ data in deep water Gulf of Mexico. This tomography provides the method to utilize surface offset gathers from surveys with different shot and receiver datums together for joint tomography. By incorporating both OBN and streamer data in tomography, the aperture and coarse sampling limitations of OBN can be overcome, and the full azimuth coverage, better low frequency, longer offsets, and higher S/N of OBN data can benefit tomography. Subsequently we are able to build a better velocity model.
