Abstract
A01 SUPPRESSION OF FREE-SURFACE EFFECTS FROM MULTICOMPONENT SEA-FLOOR DATA 1 Summary. We use multicomponent sea-floor data to suppress receiver-side ghosts and free-surface multiples and to datum the results of ghosts and multiple suppression from the sea-floor to the free-surface. Both steps – deghosting and multiple suppression - are applied trace by trace to the tau-p transformed common receiver gathers. 2D datuming for structures with inline lateral variations is performed in the same tau-p domain. Therefore effective suppression of aliasing in the tau-p transform is of crucial importance. In addition to the dip filter our antialiasing protection is based on simple
