Removal of Intrabed Multiples by Deterministic Deconvolution

摘要

Intrabed multiples, either due to shallow reverberations or the presence of manythin layers, can have a detrimental effect on the signature of deeper reflections. The authors discuss a method for removing this type of multiples. It can be viewed upon as a deterministic counterpart of well-known predictive deconvolution methods and is aimed at estimating the inverse transmission operator of a subsurface region, directly from its reflection response. The method is illustrated by applying it to a subsurface model consisting of 10,000 layers and appears to be able to remove all intrabed transmission effects.
