Accurate definition of the depth structure of a salt sill, with two-dimensionalseismic data, is made difficult because of sideswipe, raypath bending, and velocity anomalies. A procedure is described, using three-dimensional forward modeling and map migration, which leads the interpreter to a geophysically plausible model.
