چکیده:

A new implementation of the normal-moveout (NMO) correction is described in this paper that is routinely applied to common-midpoint (CMP) reflections prior to stacking. This method automatically avoids the undesirable stretch effects that are present in conventional NMO (NMO stretch). Under this method, a significant range of large offsets, that would normally be muted in the case of conventional NMO, can be kept and used in stack. The method improves the resolution of CMP stack. The use of this method is illustrated by its application to synthetic and real datasets.
