Calibrated thermal maturity grids for the 3D petroleum systems model of the Williston Basin, USA

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-04-26T00:00:00Z
The thermal maturity grids are results generated from the petroleum systems model for five major source rock intervals, which include, from youngest to oldest, the Tyler, Mission Canyon, upper part of the Bakken, Red River, and Icebox Formations. The units are in equivalent vitrinite reflectance using the Nielsen et al. (2017) Basin%Ro kinetic model. Note: these grids represent the modeled thermal maturity of the source interval horizon and may extend beyond the lithostratigraphic extent of the inferred source rock; they cover the entire petroleum systems model area of interest. This is a child item of a larger data release titled "Data release for the 3D petroleum systems model of the Williston Basin, USA".
