Abstract:
1. A method for predicting interbed multiples, comprising: generating trace geometries for one or more desired shot-side traces, one or more desired receiver-side traces, and one or more desired interbed multiple generator traces, for a first target trace; extracting a first set of reflections at the interbed multiple generator layer from one or more recorded traces closest to the desired interbed multiple generator traces; extracting a second set of reflections below the interbed multiple generator layer from one or more recorded traces closest to the desired shot-side traces; extracting a third set of reflections below the interbed multiple generator layer from one or more recorded traces closest to the desired receiver-side traces; and estimating the interbed multiples for the first target trace based on the first set, the second set, and the third set.
