The well-to-seismic tie is not only the best way to tie seismic data back to a ground truth by comparison with well-log data using synthetic seismograms for seismic interpretation purposes, but it also provides very valuable seismic anisotropy information. In this paper, we present our concepts and an example of use of a well-to-seismic tie to indicate seismic anisotropy. In addition, rock-physics analyses were incorporated to update the subsalt velocity in a deepwater area of the Gulf of Mexico.
