Abstract
Summary
We present a joint tomography flow for ocean bottom node (OBN) and streamer wide azimuth data in deep water Gulf of Mexico. This tomography method uses 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 OBN strengths of full azimuth coverage, better low frequency, longer offsets, and higher signal-to-noise ratio of OBN data can be exploited. The result is better velocity model building.
