... We extend applications of a recently developed method for internal multiples prediction (van der Neut and Wapenaar, 2016) to a streamer dataset from a shallow-water survey. The internal multiples being predicted are all the internal multiples arriving later than a reflection from a fictitious...

... in the offset-time domain. The impact of random spatial sampling on internal multiple prediction is tested in this domain. This study is carried out on both a two-interface synthetic model and a physical modeling dataset recorded in the CREWES Physical Modeling Facility. We find that the 1.5D version...

This paper describes the practical application of the zero-offset inverse scattering internal multiple prediction theory to time migrated data. This is a fast and effective way of getting migrated time migrated internal multiple seismic cube that can...
