Brief ISS tutorial - Arthur Weglein*
Analysis, testing and comparison of the Inverse Scattering Series (ISS) Free- Surface Multiple-Elimination (FSME) algorithm, and the industry-standard SRME plus energy minimization adaptive subtraction for isolated free-surface multiples and multiples proximal to and interfering with other events - Chao Ma, Qiang Fu and Arthur B. Weglein
A multidimensional method that eliminates internal multiples: a new toolbox option for removing internal multiples that interfere with primaries, without damaging the primary, and without any knowledge of subsurface properties - Yanglei Zou, Chao Ma and Arthur B. Wegleinem>*
Testing, evaluating and analyzing the inverse scattering series internal multiple attenuation algorithm for an inelastic earth without knowing or needing the elastic or inelastic subsurface properties - Jing Wu and Arthur B. Weglein*
Analysis of the Inverse Scattering Series (ISS) internal multiple attenuation and elimination algorithms as effective tool box choices for absorptive and dispersive media with isolated and interfering events —A guide for effectively applying the current ISS internal multiple elimination algorithm with absorptive and dispersive media - Qiang Fu, Yanglei Zou, Jing Wu, and Arthur B. Weglein

A brief tutorial on Green’s theorem for Stolt CIII migration and a comparison with RTM - Arthur B. Weglein*
A user guide for implementing Stolt CIII migration and RTM for heterogeneous media: a study and comparison of the difference in resolution provided by these two migration methods - Qiang Fu, Yanglei Zou, Fang Liu and Arthur B. Weglein*
A tutorial on the logic and new math-physics methods development within M-OSRP required to address pressing and prioritized seismic processing challenges. Topics will include: 1. A comprehensive framework for all the preprocessing and processing methods being developed within M-OSRP 2. Why is the logic behind the ISS methodology so elusive to many- especially to mathematicians, physicists, geophysicists and geologists- in contrast, why is the logic behind indirect methods and model matching so accessible? 3. Why solving a forward problem in an inverse sense ( model matching,AVO, FWI) is not the same as solving an inverse problem directly-and why does it matter? 4. What are the conceptual and practical advantages of solving an inverse problem directly in terms of seismic processing and interpretation objectives- and improving drill success rates? 5. What do all direct inverse methods for structural determination and amplitude analysis communicate on the role of primaries and multiples? 6. What do we consider as the appropriate role for direct and indirect - Arthur B. Weglein
