This paper develops a new method of residual static correction based on matching pursuit algorithm. Taking advantage of matching pursuit algorithm in seismic signal decomposition and reconstruction, CMP gathers are decomposed into different atoms and the residual statics are applied to each atoms of CMP traces within a certain time window. Then, the corrected atoms are used to reconstruct the seismic signal. We apply the proposed method and cross-correlation residual static correction to synthetic and real datasets for comparing their results. Results of these two methods indicate that new method can eliminate residual moveout efficiently and generate higher temporal resolution of prestack gathers.Presentation Date: Tuesday, September 17, 2019Session Start Time: 9:20 AMPresentation Start Time: 10:10 AMLocation: Poster Station 7Presentation Type: PosterKeywords: statics, algorithm, moveoutPermalink: https://doi.org/10.1190/segam2019-3214593.1FiguresReferencesRelatedDetails 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 Jin Zhao, Jingye Li, and Jiwei Cheng, (2019), "Seismic gathers residual static correction based on matching pursuit algorithm," SEG Technical Program Expanded Abstracts : 2918-2922. https://doi.org/10.1190/segam2019-3214593.1 Plain-Language Summary KeywordsstaticsalgorithmmoveoutPDF DownloadLoading ...
