It can overcome the disadvantage of conventional Constrained Sparse Spike Inversion through considering the influence of sedimentary environment which can be characterized by the seismic waveform similarity. An integrated workflow is established to execute the inversion process which includes well-seismic tie, horizon interpretation, forward modelling, waveform clustering and high-resolution inversion. The case study demonstrates the new approach is applicable and efficient for carbonate karst reservoir prediction and the estimated results agree with the prior geology information and well log analysis.Note: This paper was accepted into the Technical Program but was not be presented at the 2019 SEG Annual Meeting in San Antonio, Texas.Keywords: facies, high-resolution, inversion, reservoir characterizationPermalink: https://doi.org/10.1190/segam2019-3213792.1FiguresReferencesRelatedDetailsCited byHeterogeneous reservoir prediction of ultra-deep strike-slip fault-damaged zone constrained with local seismic anomaly data12 July 2022 | Earth Science Informatics, Vol. 15, 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 Jing Zhang, Bingyi Du, Hailiang Li, Qingchun Jiang, Tao Hao, Lei Wang, and Weiwei He, (2019), "High-resolution inversion based on lithology faces-control of karst reservoir: A case study from Sichuan Basin, China," SEG Technical Program Expanded Abstracts : 3389-3393. https://doi.org/10.1190/segam2019-3213792.1 Plain-Language Summary Keywordsfacieshigh-resolutioninversionreservoir characterizationPDF DownloadLoading ...
