IM006 MULTIDIMENSIONAL MULTIPLE ATTENUATION OF OBS DATA A. OSEN and L. AMUNDSEN Statoil Research Centre 7005 Trondheim Norway Introduction Previously Amundsen (2001) has presented a general wave-equation method for multidimensional signature deconvolution (“designature”) and elimination of free-surface related multiples (“demultiple”) from four-component ocean bottom seismic (OBS) data. Contrary to other free-surface multiple attenuation schemes the method requires no information about the source signature. Here we consider implementation and testing of the multidimensional multiple attenuation and designature scheme for general inhomogeneous media. The designature and demultiple algorithm may be divided into two major computational steps. First a multidimensional “deconvolution operator” being
