B032 Data-Driven Regularization/Extrapolation Using Interferometry with the Direct Wave A.C. Ramírez Pérez* (M-OSRP University of Houston) K. Hokstad (Statoil R&D Trondheim Norway) & E. Otnes (Statoil R&D Trondheim Norway) SUMMARY We present a method to extrapolate and regularize data. The procedure is based on crosscorrelation of the measured field with the direct wave and it is independent of earth properties. The method is derived from Green’s theorem and in principle requires the total field and its normal derivative at the receiver locations. Hence it is well-suited for OBS data. In order to apply the method to towed streamer data certain
