Abstract

Salt-related converted waves (C-waves) can be significant in conventional marine data. We explore the elimination of high-amplitude C-waves from the base of salt reflection as a way to improve subsalt imaging. We propose a dual-leg 3D acoustic modelling method to provide guidance for salt-related C-wave artifact identification and removal. Real data studies are presented to show the artifacts removed through pre-migration adaptive subtraction and post-migration Vector Offset Output RTM stacking. Additionally, we study dual flood RTM imaging for feasibility of using C-wave energies to aid in base of salt interpretation.
