oa Marine Wide-azimuth Seismic for Signal to Noise Enhancement and Multiple Suppression

Wide azimuth marine surveys have been successful in the deep water Gulf of Mexico at imaging beneath mobile salt. They have also shown that wide azimuth surveys can have benefits for multiple and noise suppression. Therefore, we should ask if these effects will be of benefit in other parts of the world with multiple and noise problems – do they still apply in shallower water, or in provinces with faster sedimentary velocities. The simplest answer is yes, but sampling criteria are likely to mean we will need to use different recording geometries for different geological settings – just as we do for conventional surveys.
