Data Driven Surface-Related Multiple Elimination on Walkaway VSP Data

Abstract

Surface-related multiple elimination (SRME) can predict and attenuate all multiples generated by the air-water interface. Earlier SRME schemes for walkaway VSP (WVSP) data involve a model in order to generate primaries recorded at the air-water surface which are not recorded in a WVSP experiment. In this paper, we generate surface data from the WVSP using interferometry. Using this approach we obtain a data driven SRME scheme for WVSP data. The SRME algorithms developed for marine seismic can be used with minor revisions.
