Results Of Suppression Of Multiples The Kbc Method

New results are presented based on the Kalman-<br>Bucy-Crump (KBC) theory, here adapted for prediction<br>(KBCP), and applied to the suppression of symmetrical<br>and of nonsymmetrical multiples. These<br>multiples are related to upper low velocity layers<br>(weathering zone) and to deeper high velocity layers<br>(diabase sills). The method is to be compared to the<br>Wiener-Hopf-Levenberg (WHL) classical solution for<br>prediction in reflection seismics. The cases studied<br>are for (1D) zero off-set, and for (2D) time sections.
