Inverse scattering internal multiple prediction on data from a physical modeling experiment

The internal multiple attenuation algorithm derived from the inverse scattering series is a powerful means to predict and suppress interbed multiples. Examples of significant multiple suppression in marine field data cases have been well-documented, and more recently land application has also had positive outcomes. Especially as applicability moves onto land, questions of (1) optimal choice of integration limits, (2) minimum allowable proximity of sub-events, etc., grow in importance. One possible way of systematically studying these issues is via physical modeling. Using the CREWES physical modeling facility, a large contrast layered target was designed to generate size able interbed multiples in near offset reflection data. A 1D version of the prediction component of the algorithm was applied to data with some minimal preprocessing. In this paper we present our initial results and preliminary conclusions.
