A method for removing internal multiples from collected data, such as seismic data. The method includes predicting internal multiples for each horizon in a plurality of horizons that created the internal multiples. The internal multiples may be predicted from the seismic data in one pass. After predicting the internal multiples, the method includes creating a separate model of internal multiples for each horizon based on the predicted internal multiples for each horizon. The method then iteratively subtracts each separate model of internal multiples for each horizon from the seismic data.

Attenuating internal multiples from seismic data

Methods for attenuating multiple reflections in seismic data by predicting the multiples using wavefield extrapolation modeling, which uses one-way wavefield propagation in both the up and down directions to predict internal multiples up to a specified order.
