Dynamic predictive deconvolution
WebThe least-squares prediction filter with unit prediction distance is equivalent within a scale factor to the least-squares, zero-lag inverse filter. The use of least-squares prediction filters with prediction distances greater than unity leads to the method of predictive deconvolution which represents a more generalized approach to this subject ... WebFor comparison, we use the traditional predictive deconvolution to squeeze all wavelets (figure 5a), the filter length N is 10 and the prewhitening factor is 0.0001. The traditional method produces a reasonable result at the high-frequency locations, however, the predictive deconvolution still loses part of the original amplitudes.

WebSep 10, 2024 · After compensation for the amplitude decay, the Chirp and Boomer seismograms are better able to approximate the key condition for a later processing step, i.e., the predictive deconvolution. This algorithm assumes that the received seismogram is the convolution of a (quasi)-stationary waveform with a random Earth reflectivity, whose …

WebPredictive deconvolution The problem is now to estimate a predictive filter f with the input traces. As the input traces have 512 samples, I took the length of the filter equal to 50 samples. The residuals of L 2 and L 1 deconvolution on the pure trace are similar (Figure ). As the input wavelet is minimum-phase, the L 2 deconvolution is efficient. WebPredictive deconvolution is the use of information from the earlier part of a seismic trace to predict and deconvolve the latter part of that trace. In processing procedure, the …
WebA time‐varying deconvolution method has been developed which is based upon adaptive linear filtering techniques. This adaptive deconvolution is applicable for use in processing reflection seismic data which contain multiples with periods that vary with traveltime. Filter coefficients are designed for each sample of the input trace using an adaptive algorithm. …
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.
