Inverse scattering series internal multiple prediction with depth dependent scalars

Andrew Iverson and Kris Innanen


Interbed multiples continue to be detrimental to the processing and interpretation of seismic data. One prospective method to attenuate interbed multiples uses the inverse scattering series developed by Weglein et al in the 1990’s. The method predicts internal multiples from the recorded data with no additional subsurface information requirements. The issue addressed in this report involves the amplitudes of the predicted internal multiples. This report displays how a depth dependent scalar can be added to the algorithm to account for errors in the prediction amplitude and improve accuracy for specific cases. The location of the scalar application in the inverse scattering series is outlined.
