ADAPCIGs are obtained from common shot migration gathers. The test of theoretical model shows that, whatever the bed is flat or dipping, the peak amplitude of ADAPCIGs reflects the information of reflection coefficients. Therefore it really reflects AVA information. The superiority of ADAPCIGs is also presented in real data processing.Permalink: https://doi.org/10.1190/1.3603748FiguresReferencesRelatedDetails Beijing 2009 International Geophysical Conference and Exposition, Beijing, China, 24–27 April 2009ISBN (print):978-1-56080-284-6ISSN (online):2159-6832Copyright: 2009 Pages: publication data© 2009 Copyright © 2009 Society of Exploration Geophysicists and China Petroleum SocietyPublisher:Society of Exploration Geophysicists HistoryPublished: 28 Jun 2011 CITATION INFORMATION Li‐yan Zhang, Jian‐min Wang, and Liu Yang, (2009), "Converted‐wave angle‐domain amplitude preserving common image‐gathers," SEG Global Meeting Abstracts : 223-223. https://doi.org/10.1190/1.3603748 Plain-Language Summary PDF DownloadLoading ...
