With the data residual calculated in localized windows in time and space, DMFWI provides a robust velocity-model update using the total energy in the data including both diving wave and reflections. The applications to a streamer dataset and a sparse node dataset with ultralong offsets in Gulf of Mexico shows its capability to resolve large velocity errors and give significant uplift on sub-salt image.Presentation Date: Tuesday, October 13, 2020Session Start Time: 8:30 AMPresentation Time: 10:35 AMLocation: 361FPresentation Type: OralKeywords: full-waveform inversion, algorithm, subsalt, ocean-bottom node, imagingPermalink: https://doi.org/10.1190/segam2020-3427610.1FiguresReferencesRelatedDetailsCited byCan elastic waveform inversion benefit from inverting multicomponent data?Carlos Pérez Solano and René-Édouard Plessix1 March 2023 | The Leading Edge, Vol. 42, No. 3Application of full-waveform inversion to land data: Case studies in onshore MexicoCristina Reta-Tang, James Sheng, Faqi Liu, Alfredo Vázquez Cantú, and Alejandro Cabrales Vargas1 March 2023 | The Leading Edge, Vol. 42, No. 3Toward high-fidelity imaging: Dynamic matching FWI and its applicationsYi Huang, Jian Mao, James Sheng, Mike Perz, Yang He, Feng Hao, Faqi Liu, Bin Wang, Seet Li Yong, Daniel Chaikin, Adriana Citlali Ramirez, Matt Hart, and Henrik Roende1 February 2023 | The Leading Edge, Vol. 42, No. 2Influence of shear velocity on elastic full-waveform inversion: Gulf of Mexico case study using multicomponent ocean-bottom node dataYongchae Cho, Carlos Pérez Solano, John Kimbro, Yi Yang, René-Édouard Plessix, and Kenneth Matson23 August 2022 | GEOPHYSICS, Vol. 87, No. 5Velocity model building with a time shift objective function: Gulf of Mexico examplesYi Yang, Ken Matson, Tadas Krupovnickas, Mark Huiskes, Rene-Edouard Plessix, and Sijmen Gerritsen15 August 2022Full-waveform inversion and FWI imaging for land dataJames Sheng, Cristina Reta-Tang, Faqi Liu, Alfredo Vázquez Cantú, and Alejandro Cabrales Vargas15 August 2022Low-frequency, long-offset elastic waveform inversion in the context of velocity model buildingRené-Édouard Plessix and Tadas Krupovnickas3 May 2021 | The Leading Edge, Vol. 40, No. 5New-generation simultaneous shooting sparse OBN survey and FWI delineate deep subsalt structures in the Greater Mars-Ursa areaHenrik Roende, Dan Chaikin, Yi Huang, and Konstantin N.
