GEOLOGIC STUDY AND RESERVOIR EVALUATION OF THE VICKSBURG FORMATION, SOUTH TEXAS - Available in RAPID
This study was initiated to provide a detailed geological, petrophysical, and engineering characterization and evaluation of Vicksburg sandstones from conventional cores. This project is base on approximately 5,000 feet of core from thirty-nine (39) project wells with cores that span subsurface depths ranging from 6,100 feet to 16,200 feet. Thirty-eight (38) of the wells are located in the South Texas counties of Nueces, Kleberg, Jim Wells, Kennedy, Brooks, Starr and Hidalgo. One well is located in Chambers County in the Houston Embayment.
The objectives of the study were to provide participating companies with detailed geological, petrophysical, and engineering characterizations and evaluations of productive and potentially productive Vicksburg reservoir sandstones. More specifically, the study provides participants with data and interpretations regarding:
The data and interpretations for the individual project wells are provided as well as a final report volume that contains a regional summary derived from the evaluation and integration of data obtained from project wells. Results from special core analysis tests and rock-fluid compatibility tests are also included in the final reports with specific recommendations regarding drilling and completion practices.
The Vicksburg Rock Catalog analytical program was designed to characterize the geological, petrophysical, and rock-fluid compatibility properties of the various Vicksburg reservoir types observed in the regional study wells. The rock catalog entries will serve as reference analogs for more accurate estimates of formation parameters and producibility of non-cored zones of interest. The catalog data can be applied to many areas of Vicksburg exploration and exploitation, some of which include:
Each Vicksburg rock type in the catalog is presented in a format which characterizes, as completely as possible, the rock types' various geological and petrophysical properties. Other support data, such as open-hole logs, drilling and completion procedures, and production test data, will be provided for each rock-type entry.
