The calculated petrophysical rock types were obtained using the Windland R35 (Gunter, et al, 1997) equation which includes information collected from core data: pore throat size distribution, porosity, and permeability. Permeability and rock type curves at the non‐cored wells were predicted using available core data. Several consistency checks and quality control revisions were applied to obtain the results from these predictions in order to have a reliable relationship between petrophysical properties and petrophysical rock types. The resulting curves at the depth interval of interest were correlated throughout the field and calibrated with 3D seismic data. In order to obtain the correct parameter to enhance spatial rock type distribution, seismic attribute analysis was performed and a well log vs. seismic attribute cross‐plot relationship was established to predict petrophysical rock properties in the interval. The predicted petrophysical rock type map provides extremely valuable constraints for the development of the field. The results clearly indicate that the application of this workflow is valuable for determining new locations to be drilled either for production or injection.Permalink: https://doi.org/10.1190/1.3059215FiguresReferencesRelatedDetails SEG Technical Program Expanded Abstracts 2008ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2008 Pages: 3713 publication data© 2008 Copyright © 2008 Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 15 Dec 2008 CITATION INFORMATION Francisco Cheng, Kumar Ramachandran, and David Contreras, (2008), Comparison of petrophysical rock types from core and well‐logs using post‐stack 3D seismic data: Field example from Maracaibo‐Venezuela, SEG Technical Program Expanded Abstracts : 1595-1599. https://doi.org/10.1190/1.3059215 Plain-Language Summary PDF DownloadLoading ..." @default.
