Paper Summary
A data driven 3D true azimuth surface related multiple elimination (SRME) technique can be quite effective in removing surface related multiples for both narrow azimuth (NAZ) surveys as well as wide azimuth (WAZ) surveys. To achieve the true azimuth multiple prediction, azimuth information should be preserved in both data preparation/interpolation, as well as during the multiple prediction. Examples show true azimuth 3D SRME effectively attenuate the surface multiples including the diffracted multiples generated from rugose water bottom. Combining WAZ with NAZ surveys could further improve the SRME multiple prediction quality. It also improves the final RTM images.
