Claerbout and Muir illustrated the advantage of an L1‐norm misfit function in seismic processing with erratic data. Predictive 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 seismic processing the purpose of deconvolution is to remove (or collapse) the seismic wavelet. Deconvolution, in seismic data processing, shortens reflection waves and reduces the ghost effect that can might occur because of instrumentation, reverberations, or multiple reflections. - 1. Deconvolution is a process that increase vertical resolution of seismic data by compressing the source wavelet into a zero phase spike (spiking deconvolution) and also a powerful tool to remove periodic repetitive multiples (predictive multiples).
