Abstract

We discuss the application of linear Radon transform (LRT) filtering for the supression of complex geometry related multiples in common offset and stacked sections. Common offset sections have to be considered for amplitude versus offset (AVO) analysis. Complex geometries give rise to events of non-hyperbolical moveouts that cannot be properly modeled by parabolic Radon transforms (PRT) and thus are not sufficiently attenuated via PRT filtering. Moreover, wave-equation based methods are still unable to deal with peg-leg multiples. On the other hand, in structurally complex areas, multiples and primaries are in general characterized by . different dips in the stack or in common offset sections allowing discrimination via LRT. For stacked sections, when more radical procedures such as internal muting are mandatory, the LRT filtering on a limited offset range, may be worthwhile.
