When predictive deconvolution is applied to seismic
traces usïng prediction distance longer than one
sample interval, the output seismic wavelet is a
truncated version of the input wavelet, and is not
minimum phase. Therefore when predictive
deconvolution before stack is followed by
predictive deconvolution after stack, the decon
after stack sometimes produces a serious distortion
of the wavelet. This happens when the after-stack
prediction distance is shorter than the
before-stack prediction distance.
