An efficient and accurate algorithm for constructing common scatter point gathers

Xinxiang Li and John C. Bancroft

ABSTRACT

The equivalent offset migration (EOM) technique has been successfully used for field data from different areas. As an efficient alternate approach of pre-stack Kirchhoff time migration, it involves a procedure of constructing common scatter point (CSP)gathers. An efficient and accurate algorithm for constructing CSP gathers is presented. This method will improve the accuracy, quality and the speed in forming the accurate CSP gathers as well as benefits the poststack image section.
