We propose a phase-only reflection full-waveform inversion (PRFWI) for a high-resolution velocity-model update. To avoid amplitude problems in RFWI, we choose an object function of local cross correlation between recorded data and synthetic data with envelope normalization. PRFWI uses the phase-only information to resolve the far-angle traveltime mismatches, which can provide a robust velocity-model update. The application on Crean 3D dataset in Europe shows its capability to resolve local velocity errors.Presentation Date: Tuesday, September 17, 2019Session Start Time: 1:50 PMPresentation Time: 3:30 PMLocation: 225BPresentation Type: OralKeywords: full-waveform inversion, reflection, high-resolutionPermalink: https://doi.org/10.1190/segam2019-3214447.1FiguresReferencesRelatedDetailsCited byToward 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. 2Improving subsalt images using reflection FWI on WAZ data: Examples from the Gulf of MexicoMaksym Kryvohuz, Yihua Cai, Sebastian Ramirez, Robert Schelstrate, and Gislain Madiba15 August 2022Practical solutions for reflection-driven FWI and application to Gulf of Mexico datasetsMax Liu, René-Édouard Plessix, Yi Yang, Jeffrey Vander Hurst, Na Shan, Rob Schelstrate, Colin Perkins, and Vanessa Goh15 August 2022Characterizing near-surface structures at the Ostia archaeological site based on instantaneous-phase coherency inversionJianhuan Liu, Ranajit Ghose, and Deyan Draganov14 June 2022 | GEOPHYSICS, Vol. 87, No. 4Multi-channel dynamic matching full-waveform inversionJian Mao, James Sheng, Yi Huang, Feng Hao, and Faqi Liu30 September 2020Multiscale phase inversion for 3D ocean‐bottom cable data21 October 2019 | Geophysical Prospecting, Vol. 68, No. 3 SEG Technical Program Expanded Abstracts 2019ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2019 Pages: 5407 publication data© 2019 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 10 Aug 2019 CITATION INFORMATION Jian Mao, James Sheng, and Guy Hilburn, (2019), "Phase only reflection full-waveform inversion for high resolution model update," SEG Technical Program Expanded Abstracts : 1305-1309. https://doi.org/10.1190/segam2019-3214447.1 Plain-Language Summary Keywordsfull-waveform inversionreflectionhigh-resolutionPDF DownloadLoading ...
