Presentation Title & Author	Video
Technical Program begins: Meeting Overview—IDENTIFYING AND RESPONDING TO PRIORITIZED AND PRESSING SEISMIC EXPLORATION CHALLENGES - Arthur B. Weglein
Green’s theorem tutorial Part I: for wave field separation (separation of reference and scattered wave-fields, and for de-ghosting) - Arthur B. Weglein
Predicting deghosted pressure and multicomponent displacements at the ocean bottom - Jing Wu
Using depth-variable towed streamers for offshore preprocessing in the (x-ω) domain to predict scattered wave and receiver deghosted data above the streamers — towards on-shore and ocean bottom application with variable topography. - Zhen Zhang
Onshore preprocessing: (1) reference wave removal including ground roll and deghosting, and (2) achieving that objective with a reduced data requirement - Jing Wu
The significance and impact of incorporating a 3D point source in deghosting for data coming from a 1D subsurface - Xinglu Lin
A new method for deghosting on a depth variable acquisition surface by combining Green’s theorem and a Stolt extended Claerbout III wave prediction for one way propagating waves - Jing Wu
Initial tests for the new two-step strategy of deghosting that combines Green’s theorem and a Stolt extended Claerbout III wave prediction for one way propagating wave on a non-horizontal measurement surface for marine case - Yuchang Shen and Zhen Zhang
Green’s theorem tutorial Part II: for wave field prediction: imaging conditions, one-way and two-way wave equation migration for a more effective and fundamentally and practically more capable migration (Stolt extended Claerbout III imaging for migrating in a volume with two way propagating waves) (Glossary of imaging conditions: in our usage, Claerbout imaging I is the exploding reflector model, Claerbout II imaging , is the space and time coincidence of up and downgoing waves, and Claerbout III refers to predicting a coincident source and receiver experiment at depth at time equals zero.) These migration methods require a velocity model. - Arthur B. Weglein
The Claerbout II imaging principle resides behind all current leading edge RTM methods used in industry. Claerbout II and all RTM methods are intrinsically high frequency approximations independent of how they are extended or implemented. . Benefits of the new Stolt extended Claerbout III imaging for two way propagating waves: (1) provides a new and first migration method that’s equally effective at all recorded frequencies at the target and reservoir and hence added-value and advantages for both structural determination and amplitude analysis in migration and (2) provides clarity on the role of primaries and multiples in imaging and migration - Arthur B. Weglein
Stolt extended Claerbout III imaging for two way propagating waves provides a clear and definitive response to the role of primaries and multiples in imaging and inversion: Multiples: signal or noise? - Arthur B. Weglein
Only primaries are required for imaging and inversion, but when there is inadequate acquisition of primaries, multiples can be used to provide an approximate image of an unrecorded primary - Arthur B. Weglein
A tutorial on the inverse scattering series: distinct isolated task subseries for removing free surface and internal multiples Multiples: part I: Background/Introduction/Update Multiple attenuation: recent progress, and a plan to address open, prioritized and pressing issues and challenges - Arthur B. Weglein
Thesis executive summary: On-shore ISS internal multiple attenuation: first field data tests - Qiang Fu
Thesis executive summary plus recent advances: positive impact of incorporating a 3D point source in the processing steps (deghosting, multiple removal) for a 1D/2D subsurface - Xinglu Lin
Thesis executive summary: The ISS data comprehensive internal multiple attenuation algorithm that accommodates primaries and internal multiples in the input data - Chao Ma

An alternative Inverse-Scattering-Series (ISS) internal multiple eliminator for the first-order internal multiples generated by the ocean bottom - Xinglu Lin
The Claerbout II (CII) imaging condition (current leading edge RTM) removing back -scatter artifacts - Qiang Fu
