Modified Form of Reverse Time Migration Tuned to Multiple

Recent field tests show the feasibility of achieving superresolution in migration images. To partly realize this with practical exploration data, we introduce a modified form of reverse time migration, denoted as GDM, with an imaging condition tuned to multiple scattered events. GDM imaging of the SEG/EAGE synthetic data shows higher resolution in the migration image, but at the expense of an increased noise level. A limitation is that superresolution property can only be achieved with a highly accurate velocity model.
