An independent processing concept based on equivalent offsets: from statics to migration

John C. Bancroft


It is proposed that a procedure based on the principle of equivalent offsets and CSP gathers will provide the necessary tools for accurate prestack migration without the need to form CMP gathers or a stacked section.

The processing of conventional prestack migrations is based on the concept of CMP gathers and creating a stacked section, even if only used for static analysis. The objective of this paper is to outline a processing strategy that is completely independent of both CMP gathers and the stacked sections.
