Abstract

Summary

This work explores different approaches for the image domain least-squares migration with Point Spread Functions (PSFs) computed in pre-stack and post-stack domain, using both Reverse Time Migration (RTM) and Kirchhoff migration engines. We also present two applications in 3D datasets of deepwater offshore of Brazil. Both strategies showed that least-squares migration provide an uplift in the migration amplitudes and resolution even on geologically complex models.
