M-OSRP: A sample of recent advances and progress, February, 2022
Posted on January 12, 2022
Dear Colleagues and Friends,
I hope that this note finds you very well.
Below please find a sampling of papers and video presentations on a range topics that M-OSRP has recently pioneered, developed and delivered. I look forward to staying in touch.
Sending you my Warmest Best Wishes for a Joyful Winter Holiday Season and a Healthy and Happy the New Year, Arthur

A FEW DOCUMENTS, PUBLISHED PAPERS AND VIDEOS WITH SYNCED SLIDES
In the link below, please find a note and logical framework that help to determine whether a problem that we are interested in is the problem we need to be interested in - and the unique role of direct inverse methods in that determination. This paper, and the analysis therein, are transferable to all fundamental physics research, and application-where the interest is in providing new knowledge and insight and making significant progress, delivering relevant differential impact, and capability.
THE ‘WHY’ AND ‘HOW’ OF SEISMIC MULTIPLE REMOVAL: FEBRUARY, 2022
The playlist below provides two presentations that, taken together, provide a fundamentally new perspective, insight and understanding on Seismic Multiples. The first presentation details exactly ‘why’ multiples must 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.
There is a direct comparison of the current high-water mark of internal multiple removal capability and a new and more capable method that is called for and needed for interfering or proximal seismic events, and will soon be a tool box option.
Open issues and daunting challenges are also discussed- including those arising with on-shore and OBS plays.
The recognition of assumptions and prerequisites is essential and helps: (1) 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) was for a recent EAGE post-convention Workshop on Multiples, October 22, 2021. The link contains a few selected references, including two papers to appear in the February 2022 issue of the Journal of Seismic Exploration. One of these papers, corresponding to the second presentation, is co-authored with Jing Wu, Frederico Xavier de Melo, John T. Etgen and Jim Mayhan.

A SINGLE COMPREHESIVE LOGIC AND OVERVIEW OF ALL OF THE CONCEPTS AND METHODS PIONEERED, DEVELOPED AND DELIVERED FROM M-OSRP
The video in the link below provides a development of all the methods and projects pioneered, developed and delivered from within M-OSRP (in the above seismic processing tree and linked chain) from a single simple starting point, the field due a localized source in a homogeneous whole source. That single comprehensive overview of all the previous and current M-OSRP research projects and methods can be found in

A RECENT M-OSRP ANNUAL TECHNICAL REVIEW, WITH A MENU, VIDEOS AND SYNCED SLIDES
This link below provides a menu for all the video presentation from the 2018 M-OSRP Annual Technical Review.
http://www.mosrp.uh.edu/events/annual-meetings/meeting-18
Within that M-OSRP Annual Technical review, and of particular interest for the 2019 SEG/KOC Workshop, defining and addressing on-shore challenges, are the advances by Dr. Jing Wu for on-shore ground roll and reflection data prediction without damaging either, and for on-shore de-ghosting, and all subsequent processing methods and goals.
REMOVING THE NEED TO KNOW, ESTIMATE OR TO DETERMINE NEAR-SURFACE PROPERTIES FOR ON-SHORE AND OBS PROCESSING
A recent development (Weglein, 2022) provides a new concept, set of methods and Green’s theorem and ISS algorithms that remove the need to know, estimate, or to determine, both subsurface and near-surface information, that is- no information at and beneath and at the Earth’s surface (or at and beneath the ocean bottom for OBS) for all preprocessing and processing objectives. The current inability to determine adequate near surface properties represents a major obstacle for on-shore and OBS seismic E&P effectiveness. We have a new concept and set of algorithms within our pipeline of capability and delivery that directly addresses that problem, by developing a suite of new effective methods that do not require, or have any interest in knowing any subsurface and near surface (and at the Earth’s surface or ocean bottom) information.
