Use of information from the earlier part of a seismic trace to predict and deconvolve the latter part of that trace. Some types of systematic noise, such as reverberations and multiples can be predicted. The difference between the predicted value and the actual value is called the prediction error; it is sensitive to new information such as primary reflections. Predictive deconvolution may also be used in a multitrace sense, where one tries to predict a trace from neighboring traces. See Sheriff and Geldart (1995, 166, 168, 298).
