I hope that this note finds you very well.
The first contains a detailed response to ‘why’ exactly multiples need to be removed within all seismic processing methods, without exception (including when using multiples to approximate the image of an unrecorded primary, and for model-matching methods like FWI). The second is a ‘how’ presentation and provides a tool-box perspective on the current state of multiple removal capability. The recognition of assumptions and prerequisites is essential and helps: to make an informed cost-effective choice, among tool-box options, for a given play and circumstance, and (2) to define open issues and challenges. This second presentation ( co-authored with Jing Wu and Frederico Xavier de Melo) is for an upcoming EAGE post-convention Workshop on Multiples, October 22, 2021. Below in this link please find a few selected references, including two papers recently submitted to the Journal of Seismic Exploration. One submitted manuscript, corresponding to the second presentation, is co-authored with Jing Wu, Frederico Xavier de Melo, John T. Etgen, and Jim Mayhan.
I look forward to staying in touch. Warmest best wishes for you to be well, and to please stay healthy, happy, and safe.
