Abstract:Conventional surface seismic deconvolution methods rely on deconvolution operator repeatedly tested to be confirmed.Even so they are uncertain,and it is often difficult to obtain good deconvolution results.We propose in this paper a new surface seismic data deconvolution approach with VSP operator.First we calculate independent operator at any shot point and any receiver point from VSP data,then we use this operator in surface seismic deconvolution.Our application shows that the proposed method can both suppress multiples and improve wavelet form.
