The assembled Hessian of both simple and complex synthetic models are studied to draw conclusions regarding spatial resolution and parameter retrieval. The results indicate a strong cross-talk between the different model parameters of a common density-velocity parametrisation in EFWI. Furthermore we are able to comment on the influence of offset by comparing zero- and intermediateoffset results.Presentation Date: Wednesday, October 17, 2018Start Time: 9:20:00 AMLocation: Poster Station 7Presentation Type: PosterKeywords: full-waveform inversion, finite difference, modeling, numerical, shear wave (S-wave)Permalink: https://doi.org/10.1190/segam2018-2998233.1FiguresReferencesRelatedDetailsCited byAccelerating the multi-parameter least-squares reverse time migration using an appropriate preconditioner15 September 2021 | Computational Geosciences, Vol. 25, No. 6Global‐Scale Full‐Waveform Ambient Noise Inversion17 April 2020 | Journal of Geophysical Research: Solid Earth, Vol. 125, No. 4Uncertainty quantification in non-linear seismic inversion: A comparison of three different methods.Karen Synnøve Ohm, Wiktor Waldemar Weibull, and Xiaodong Luo10 August 2019 SEG Technical Program Expanded Abstracts 2018ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2018 Pages: 5520 publication data© 2018 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 27 Aug 2018 CITATION INFORMATION Vegard Stenhjem Hagen, Børge Arntsen, and Espen Birger Raknes, (2018), A new method for constructing the Hessian in elastic full-waveform inversion, SEG Technical Program Expanded Abstracts : 1359-1363. https://doi.org/10.1190/segam2018-2998233.1 Plain-Language Summary Keywordsfull-waveform inversionfinite differencemodelingnumericalshear wave (S-wave)PDF DownloadLoading ..." @default.
