Intrabed multiple removal: theory and practice

A novel approach to removal of intrabed multiples is<br>suggested. Based upon a Source-Signature Invariant<br>Inversion (hereafter SoSI-inversion), a relevant strategy<br>is reduced to a few sequential steps, each of those exploits<br>a technique similar to the predictive deconvolution. A<br>total number of steps is controlled by related number of<br>strong reflectors, which cause intrabed reverberations.<br>Due to linearity the codes are very fast, while a proper<br>regularization makes them fairly robust. A few examples<br>of processing synthetic/real marine data with the codes<br>in a fully automatic mode are exposed.
