Production is from a sand reservoir in the clastic section. We previously generated a Vp/Vs map by combining PP and PS travel time thickness maps that included the reservoir interval. We compare this traveltimebased Vp/Vs to that generated from impedance inversions performed on the post‐stack PP and PS data. The impedance‐based Vp/Vs is calculated by dividing the average of the inverted P‐impedance over an 8ms horizon‐based time window by the average of the inverted S‐impedance over the same window. The impedance‐based estimate appears to have higher vertical resolution. While the Vp/Vs value derived from impedance inversion is generally lower than the Vp/Vs derived from the time‐thickness ratios, they indicate similar anomalous areas. We interpret these as being sand rich. The impedance Vp/Vs and traveltime Vp/Vs values show promising new anomalies.Permalink: https://doi.org/10.1190/1.2148329FiguresReferencesRelatedDetails SEG Technical Program Expanded Abstracts 2005ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2005 Pages: 2668 publication data© 2005 Copyright © 2005 Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 07 Dec 2005 CITATION INFORMATION Chuandong (Richard) Xu and Robert R.
