Seismic Interferometry by Deconvolution – Theory and Examples

H001 Seismic Interferometry by Deconvolution – Theory and Examples I. Vasconcelos* (Center for Wave Phenomena) & R. Snieder (Center for Wave Phenomena) SUMMARY Seismic interferometry is a field of growing interest in exploration seismology. In this paper we provide the theoretical basis for performing interferometry by deconvolution. We argue models deconvolution interferometry gives the causal scattering response between any two receivers. Interferometry by crosscorrelation on the other hand gives both causal and acausal scattering responses. Even with a closed surface of integration deconvolution interferometry also gives rise to spurious events not present in its cross-correlation counterpart. These events arise from
