The channel contains intercalations of sand and shale and is considered the main reservoir; however, there are neither information about lithology nor borehole data. A pre‐stack seismic inversion was proposed, but unavailable well data makes the initial model unreliable and the result of seismic inversion highly doubtful. A non requiring well data genetic algorithm (GA) can discriminates the lithology of the channel. Tested on real traces and synthetic seismograms, the GA showed a robust performance.Permalink: https://doi.org/10.1190/1.3513815FiguresReferencesRelatedDetails SEG Technical Program Expanded Abstracts 2010 ISSN (print):1052-3812 ISSN (online):1949-4645 Copyright: 2010 Pages: 4453 publication data© 2010 Copyright © 2010 Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 21 Oct 2010 CITATION INFORMATION Edward Moncayo, Orlando Hernández, and Luis Montes, (2010), "Seismic inversion of pre stack data by a genetic algorithm," SEG Technical Program Expanded Abstracts : 458-462. https://doi.org/10.1190/1.3513815 Plain-Language Summary PDF DownloadLoading ...
