The central objective under investigation in this paper is the performance of WHL deconvolution operators for the compression of the seismic source-pulse under the conditions of non-minimum phase and density of events on the trace, as is the case supported for the real data and batch deconvolution. The method of attack to the constructed problems is centered on the information content of the autocorrelation function submitted to different conditions of: (a) the truncation and taper windows; (b) the characteristics of the operator phase (if minimum or non-minimum phase); (c) the measure of quality; (d) the whitening level; (e) the noise present and equalization; (f) the balancing of the trace; (g) the physical principles of wave propagation as expressed and limited by the convolutional model. Results can only be obtained numerically, and they are shown in the form of albums with increasing difficulties, and they demonstrate how the time windows on the autocorrelation serve to diagnostic and to improve the performance of the operators. We conclude that many questions still arise when deconvolution techniques are applied to seismic reflection data from sedimentary basins, and that the Goupillaud model is convenient for simulations through its simple and complete mathematical description.
