After careful petrophysics and rock physics diagnostics, log scale facies flags related to thick sand bodies are created. These flags are then used to color crossplots of seismic scale attributes derived from AVO inversion of PP data (Vp, Vs, and density) and inversion of post stack fast and slow PS components of a 3C‐3D survey. We show that by jointly using these five seismic attributes and facies flags (like a colored five dimensional crossplot), we can estimate the probability of thick sand bodies much better than when we crossplot two attributes at a time. Unlike commonly used approaches to map facies or lithologies from seismic data based on selecting regions in seismic attribute crossplots, our approach accounts properly for overlap among different facies and quantifies the probability of their occurrence.Permalink: https://doi.org/10.1190/1.3513098FiguresReferencesRelatedDetailsCited ByFluvial architecture and connectivity of the Williams Fork Formation: use of outcrop analogues for stratigraphic characterization and reservoir modelling29 July 2013 | Geological Society, London, Special Publications, Vol. 387, No. 1 SEG Technical Program Expanded Abstracts 2010ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2010 Pages: 4453 publication data© 2010 Copyright © 2010 Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 21 Oct 2010 CITATION INFORMATION Reinaldo J.
