Well Location, formation top, and thickness data tables 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
These data tables describe observations made on borehole geophysical logs from 16,200 wells in the Williston Basin. It includes detailed surface hole locations, true vertical depths of formation tops, and true vertical thickness values between formation tops. The data contained in the “Williston_Basin_well_data.csv” table was used in generating the formation top shapefiles (“Formation top shapefile points for the 3D petroleum systems model of the Williston Basin, USA” child item) and the true vertical thickness shapefiles (“True vertical thickness shapefile points for the 3D petroleum systems model of the Williston Basin, USA” child item). A data glossary that describes the columns in the “Williston_Basin_well_data.csv” table is also included. This is a child item of a larger data release titled "Data release for the 3D petroleum systems model of the Williston Basin, USA".
