Abstract

Reflection data consists of primary and multiply reflected events. Since most methods for estimating target properties from reflection data assume a linear model, these multiply reflected events often masquerade as, or interfere with, primaries. although there are many circumstances when current methods for removing multiples can be effective, there remain many important cases where state-of-the-art techniques are either suboptimal or fail. We present a multidimensional multiple suppression method for surface and internal multiples that doesn't depend on periodicity, differential moveout, or a model of the reflectors that generate the multiples. The method derives from separating an inverse scattering series into subseries that carry out specific tasks in the inversion process. Examples will be presented to illustrate the technique.
