Equivalent offset migration in anisotropic medium

Pavan Elapavuluri and John C. Bancroft

ABSTRACT

Equivalent offset migration (EOM) significantly improves the quality of time migrations, and is also very fast. It is shown in this paper that EOM is very robust in the presence of velocity perturbation (both due to inhomogeneities and anisotropy). A technique for extending EOM (depth) to anisotropic media is also proposed based on the shifted hyperbola NMO approach.
