Efficient 3D Internal Multiple Attenuation in the Santos Basin

Summary Internal multiples constitute a major challenge for imaging. Artefacts generated by incorrectly imaging internal multiples interfere with targets, affecting the interpretation and contaminating amplitude analyses in the reservoir. The Santos basin is a particularly challenging example of this problem because of the presence of stratified salt. We implemented a method recently proposed by Van der Neut and Wapenaar (2016) to attenuate internal multiples and successfully applied it to a data set from the Santos basin.
