WebDuring application of predictive deconvolution, we assume that within each time gate, (1) the wavelet is unknown but is minimum delay and (2) the frequency content of the reflectivity series is completely white. The validity of the random-reflectivity assumption naturally depends on the geology of the area. The frequency content of the wavelet ...
