National Assessment of Oil and Gas Project - Southwestern Wyoming Province (037) Maturation Contours

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: July 16, 2025 | Last Modified: 20240329
The maturation contours show vitrinite reflectance trends and ranges for petroleum system horizons within the Southwestern Wyoming Province. The horizons are the base of the Niobrara Formation, the top of the Frontier Formation, the base of the Mesaverde Formation, the top of the Mesaverde Formation/base of the Lewis Formation, and the top of the Lewis Formation. The ranges of vitrinite reflectance shown for the Niobrara horizons are 0.6, 0.8-1.3, and 1.3. The ranges for the top of the Frontier are less than 0.6, less than 0.8, 0.6-0.8, 0.8-1.3, and greater than 1.3. The ranges for the base of the Mesaverde are less than 0.6, 0.6-0.8, 0.8-1.1, 1.1-2.0, greater than 1.1, greater than 1.3, 2.0-2.2, greater than 2.0, and greater than 2.2. The ranges for the top of the Mesaverde/base of the Lewis are less than 0.6, 0.6-0.8, 0.8-1.1, 1.1-1.6, greater than 1.1, greater than 1.6, 1.1-2.0, 2.0-2.2, and greater than 2.2. The ranges for the top of the Lewis are less than 0.6, 0.6-0.8, 0.8-1.1, 1.1-2.0, greater than 1.1, and greater than 2.0.
