Dear Sponsors, Colleagues and Friends,

I hope that this note finds you very well. Below please find a video of a longer/extended version of an invited key-note address for the SEG/KOC Workshop: Seismic Multiples, the Challenges and the Way Forward” in Kuwait December 3-5.

“ A new perspective on removing and using multiples | they have the same exact goal | imaging primaries, recorded and unrecorded primaries | Recent advances in multiple removal”.


In the links below, and in the attachments, please find documents and video presentations that support the objectives and strategy presented in the new video in the link above, with background, context and perspective.

I hope that you find this new video, ( the extended version of a key note address at the SEG/KOC Workshop in Kuwait)in the link above, to be informative, interesting and worthwhile. As always, we thank you for your encouragement and for your support.

We send you and your family our warmest greetings for the Holiday Season and our very best wishes for Good Health and Happiness in the New Year,

This link below provides a menu for all the video presentation from the 2018 M-OSRP Annual Technical Review- we point out, and possibly of particular interest for this SEG/KOC Workshop, are the advances by Dr. Jing Wu in on-shore ground roll and reflection data prediction without damaging either, and for on-shore de-ghosting.

M-OSRP Annual Technical Review Presentations: Videos with Synced Slides and Meeting Agenda

A recent development ( Weglein, 2020) 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 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 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)information.
