    Abstract

    It has been long realized that the process of removing the effects of inland near-surface on downgoing and upcoming propagating body waves should involve an imaging or wavefield redatuming solution instead of conventional time-shifts or statics. However, a primary factor governing the success of the imaging approach is the knowledge of the velocity model between the acquisition surface and the new datum. In this paper, we first present an approach for performing redatuming without knowing the velocity model. Second, we extend this approach to determine the velocity model and perform pre-stack depth migration. Real data examples are presented.
