Predictive Deconvolution for Correction of Nonstationary Seismic Records

B028 Predictive Deconvolution for Correction of Nonstationary Seismic Records D.B. Finikov (GeoTechSystem) & M.A. Poluboyarinov* (Deco Geophysical) SUMMARY Generalization of the autoregressive model for the case of nonstationarity is used. Proposed way of parameterization of nonstationarity allows effective correction of the waveform at even significantly nonstationary seismic data. Nostationary predictive deconvolution described can be used both for elimination of reverberations and for wavelet correction and provides better results than the traditional approach.
