Click on any of the small images below to view the results of WIT's Shot Gather migration performed on the BP 2D Velocity Benchmark Synthetic. This dataset, distributed as a blind velocity test, has nonetheless gained popularity as a test of migration algorithms (when the correct velocity is used, as it is here). While the overturned flanks of the "tooth" salt on the model's right side generally require reverse time migration to be imaged correctly, notice that our code does an excellent job on the rugose salt body on the model's left side. This salt body, similar to those seen in the ultradeep Gulf of Mexico, causes severe focusing and defocusing of the wavefield, and presents lateral velocity variations that challenge many wave equation migration codes.
