What is the computational procedure for deconvolution? The predictive deconvolution process separates on the basis of two fundamental criteria: “minimum-delay” and “white.” Thus, the method of predictive deconvolution removes an estimate of the predictable minimum-delay component of the trace to yield an estimate of the nonpredictable white component, which we identify with the reflectivity. The observed data are the seismic trace recorded at the surface. The computational procedure used to determine the deconvolution operator is given by steps 1 and 2 below, and the computational procedure to carry out the deconvolution is given by step 3.
