Conclusion

We applied plane-wave migration in tilted coordinates on isotropic and anisotropic data. Plane-wave migration in tilted coordinates is potentially cheaper than shot-profile migration. For both isotropic and anisotropic data, plane-wave migration in tilted coordinates can handle overturned waves and image steeply dipping salt flanks and faults. It also images the rugose top of the salt very well. Plane-wave migration is a good tool for complex salt-body delineation.
