Pitfalls in seismic interpretation: Depth migration artifacts

Abstract

Interpretation of depth-migrated data has become increasingly common owing to advances in both post- and prestack depth processing. It is well known that depth processing can provide better imaging of complex subsurface geology than conventional time processing, depending largely on the accuracy of the depth-migration velocity model. This paper briefly describes an example of an artifact in a prestack depth-migrated image caused by an inaccurate velocity model.
