We have investigated this issue, both theoretically and empirically, and the results of our study suggest that both one‐way and two‐way wave equation PSDM methods are equally sensitive to velocity errors. However, the two‐way wave equation has greater scope than the one‐way wave equation, by imaging multiply reflected events and highly dipping reflectors, and, therefore, it is not possible to make fair comparisons for those situations not covered by one‐way methods.Permalink: https://doi.org/10.1190/1.2792945FiguresReferencesRelatedDetailsCited ByVelocity sensitivity of reverse‐time migrationGuojian Shan, Lin Zhang, Yue Wang, Tamas Nemeth, and Wei Liu15 December 2008 SEG Technical Program Expanded Abstracts 2007ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2007 Pages: 3124 publication data© 2007 Copyright © 2007 Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 14 Sep 2007 CITATION INFORMATION Matthew H.
