We also showed that changes taking place in the reservoir have different InSAR signatures from those in the overburden. This allows us to distinguish shallower overburden activities from deeper reservoir activities by investigating the InSAR inversion residual. We developed an inversion workflow that considers both overburden and reservoir strain changes and applied it to an InSAR dataset from the San Joaquin Valley. The inversion residual analysis technique we invented shows that high spatial frequency anomalies can be used to identify shallow hazards.Keywords: InSAR, inversion, resolution, shallow hazardsPermalink: https://doi.org/10.1190/image2022-3743175.1FiguresReferencesRelatedDetails Second International Meeting for Applied Geoscience & EnergyISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2022 Pages: 3694 publication data© 2022 Published in electronic format with permission by the Society of Exploration Geophysicists and the American Association of Petroleum GeologistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 15 Aug 2022 CITATION INFORMATION Zhishuai Zhang, Kurt Nihei, Andrey Shabelansky, Dimitri Bevc, Joe Stefani, William Milliken, and Gwyn Mali, (2022), "Resolution of InSAR data inversion and its application to identify shallow hazards," SEG Technical Program Expanded Abstracts : 297-301. https://doi.org/10.1190/image2022-3743175.1 Plain-Language Summary KeywordsInSARinversionresolutionshallow hazardsPDF DownloadLoading ...
