One of the exclusive beneficial characteristics of VSP data is the possibility of identifying multiple reflections, which exist in upcoming waves. As shown in this paper, powerful predictive deconvolution operators can be designed from down going waves in order to suppress the above-mentioned multiples. In this study VSP data from the south of Iran was used to suppress multiples from nearby surface 2D seismic data.
The designed operators suppressed multiples from surface seismic data properly without creating any destructive side effects on the rest of the record. The results indicate that the application of deconvolution operators not only suppressed the multiples from 2D seismic data but also produced a better correlation between VSP data and the final 2D seismic section. Seismic data and required software packages for this study were provided by the National Iranian Oil Company
