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.
