In their papers Doicin and energy associated with a specified primary event and generated by Spitz (1991,1992) demonstrated the usefulness of a 2-D implementation an identified mechanism. Removal of the targeted multiple is based on (SPLAT) specifically designed to remove the short period, flat sea a pattern recognition technique. This technique is implemented in 3-bottom peg legs associated with a strong primary event such as the D. The targeting and removal of a surface-related multiple pertaining base of the Cretaceous unconformity in the North Sea. Their published to a strong reflector is illustrated with a real data set.
