Abstract

A complication in 3D marine acquisition is that streamer feathering causes a crossline distribution of the actual midpoints. In conventional processing the individual traces are gathered in bin sorts and stacked after NMO correction. The stacked traces are posted at the centre of the bin, thus causing a posting error. This approach has some disadvantages. Depending on the feathering conditions some bin sorts will be overpopulated, while others will be underpopulated producing inconsistent stacking responses. The binstack smears the data over the bin area and thus puts a limit on the resolution. On the other hand this latter effect may be considered as a kind of spatial anti-alias filter.
