REGIONAL GEOLOGICAL, PETROPHYSICAL, AND ENGINEERING STUDY OF THE "DOWNDIP" WILCOX GROUP IN SOUTH TEXAS AND ROCK CATALOG - Available in RAPID
Formation evaluation, recognition of pay versus non pay and completion challenges are inherent to this prolific south Texas formation. This project was to designed to address these issues and aid participating companies in their exploration and exploitation activities in the trend. A full spectrum of geological and petrophysical analyses have been performed on the 171 wells with drill cuttings and conventional cores. The major objectives of this study are as follows:
The above geological, petrophysical and engineering data are compiled and evaluated to provide a regional synthesis and summary of Wilcox rock properties significant to current exploration and exploitation activities.
Individual well reports for each well are provided. The final report combines, correlates, and evaluates all of this information on a regional basis and contains information and conclusions regarding:
The Texas Wilcox Rock Catalog focuses on well completion and proper stimulation techniques for representative Wilcox rock types. It was designed to develop drilling and completion procedures compatible with the reservoir rock types defined in the regional study. Results of various geological and engineering analyses are included in catalog format for quick reference to a particular rock type. Rock type criteria include porosity, cement/clay content, and texture, along with permeability as the primary criteria used to differentiate Wilcox rock types in this study.
