Migration of Multiple Scattered Events

Recent field tests show the feasibility of achieving superresolution in migration images. To partly realize this with practical exploration data, I 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 be achieved only with a highly accurate velocity model.
