Arash JafarGandomi and Gordon Poole, CGG Summary It is well-known that standard migration is not a true inverse operation and is based on the adjoint of the forward modeling operator. Due to this approximation the resulting migrated image can often suffer from various artifacts and uneven illumination issues, especially in regions of

by CGG in collaboration with Lundin Energy Norway (Lie et al., 2018). To further increase the resolution, denser sampling of the subsurface has been proposed where the cable and receiver separa - tion is reduced and the sources and streamers are kept at a shallow depth to avoid ghost interference (Garden et al., 2017).
