Multiple removal, new opportunities

Current multiple removal algorithms make use of either differential moveout or predictability. If the<br>differential moveout between primaries and multiples becomes very small, prediction filtering is the<br>only option available. In the last decade, wave theory-based prediction-error filters have proven to be<br>very successful. In the near future, one may expect that the multireflector imaging concept may offer a<br>third option in multiple removal. Imaging avoids the adaptive subtraction process as required in<br>prediction-error algorithms. Moreover, it allows the transformation of multiples into primaries.
