Summary

The stratigraphic horizon grids were generated by picking formation tops in 16,200 borehole geophysical logs and interpolating between them in the Williston Basin of North Dakota, South Dakota, and Montana. Collectively, the horizon grids outline the structural framework of the Williston Basin from the ground surface to the crystalline basement. The grids define the boundary surfaces between geologic layers in the 3D petroleum systems model. Not every horizon in the petroleum systems model, however, ties to a specific interpreted set of formation tops (see the ‘Williston_Basin_data_overview.csv’ table to see which horizons were derived from interpreted formation tops). Some horizons were split/calculated to accommodate source rock [...]

Purpose

The stratigraphic horizon grids are a required input for running the 3D petroleum systems model. They provide constraints on burial history, and they serve as the bounding framework for defining distinct lithologic packages. These data are also useful for visualizing the regional-scale (basin-scale) subsurface stratigraphic and structural architecture. Collectively, these horizons represent a 3D model of the subsurface, and modeling steps were taken to ensure that horizons do not intersect or cross one another.
