Abstract

Conventional prestack migration methods that incorporate some form of velocity analysis, use either constant offset sections, or source gathers (shot records). When the velocities are known, these methods should give identical migrated .images. When the velocities are not known, velocity analysis is attempted by applying inverse NMO (INMO) based on arbitrary assumptions of offset, and with the prestack migration gathers formed at CMP locations.
