SAN JUAN BASIN ROCK CATALOG™ – A CATALOG OF GEOLOGICAL AND ENGINEERING PROPERTIES FOR THE MESA VERDE, PICTURED CLIFFS AND DAKOTA FORMATION IN THE SAN JUAN BASIN
The project includes measurement, documentation, and interpretation in a catalog format of the geological and petrophysical properties of rock types identified in the Mesa Verde, Pictured Cliffs, and Dakota Formations. The analyses were performed on twenty conventional core entries selected to represent a spectrum of reservoir rock types encountered in producing and potentially producing horizons. The various rock types and associated data in the San Juan Basin Rock Catalog serves as reference analogs for more accurate estimates of formation parameters, producibility and reservoir behavior of non-cored reservoir intervals. The Catalog also supplies geologists and engineers with analog data and parameters for modeling reservoir behavior and making reservoir management decisions. The San Juan Basin Rock Catalog systematically classifies and characterizes rock types encountered in these major producing formations based on the Worldwide Rock Catalog™ classification scheme.
The objectives of the San Juan Basin Rock Catalog are:
- Provide a reference manual containing “analog” sandstone and carbonate rock types for more accurate estimates of formation parameters
- Establish a comprehensive geological and engineering data base over a spectrum of rock types
- Define relationships and correlations between an extensive array of laboratory measured petrophysical data on each entry and estimates of reservoir rock properties from visual observations of core, sidewall, and/or rock cuttings material
