By adjusting the coefficient (c), we always found a good correlation between the PI and reservoir properties. Such correlation process has been considered as a statistical problem, its rock physics implication is seldom explored. Why we can always find such a coefficient which could make the derived PI correlates with the lithology/fluid well? To answer this question, we explore two widely used rock physics models for the sandstone reservoirs: consolidated (cement) sediment model, and unconsolidated (soft) sediment model. We study the modeled P-impedance and S-impedance responses and their implication on the PI correlation with reservoir properties. The workflow of using PI to predict reservoir properties is applied to a well log dataset, the PI derived results match well with reservoir properties from traditional well log analysis, which provides good opportunity for the 3D seismic reservoir characterization from the pre-stack inversion products.Presentation Date: Monday, September 16, 2019Session Start Time: 1:50 PMPresentation Start Time: 2:15 PMLocation: 305Presentation Type: OralKeywords: reservoir characterization, sandstone, rock physics, interpretation, log analysisPermalink: https://doi.org/10.1190/segam2019-3196883.1FiguresReferencesRelatedDetailsCited byImproved estimation of elastic attributes from prestack seismic data for reservoir characterizationYijie Zhou, Franklin Ruiz, Yequan Chen, and Fan Xia22 November 2019 | GEOPHYSICS, Vol. 85, No. 1 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 Yijie Zhou and Yequan Chen, (2019), "The rock physics implication of Poisson impedance and its application on sandstone reservoir characterization," SEG Technical Program Expanded Abstracts : 3523-3527. https://doi.org/10.1190/segam2019-3196883.1 Plain-Language Summary Keywordsreservoir characterizationsandstonerock physicsinterpretationlog analysisPDF DownloadLoading ...
