Suppressing Peg-Leg Multiples with Parabolic Radon Demultiple

F-36 SUPPRESSING PEG-LEG MULTIPLES WITH PARABOLIC RADON DEMULTIPLE Abstract 1 Parabolic Radon demultiple is one of the standard processing techniques for removing multiple reflection energy from seismic data. In the deep water salt dominated areas of the Gulf of Mexico this technique fails to remove some of the strong salt related multiples. This study will show how an important class of multiples peg-leg multiples can violate the underlying assumptions of parabolic Radon demultiple. This results in a strong near offset residual multiple in the resulting data. This study shows how peg-leg multiples can be removed by expanding the underlying model
