Basal heat flow from the crystalline basement and lithospheric mantle into the sedimentary column is a required boundary condition in the petroleum systems model. The model uses two basal heat flow conditions that are described using two ASCII grids that show map variations in heat flow (mW/m2). The “BHF000_BasalHeatFlow_Calib.asc” grid describes the modern-day basal heat flow calibrated to, and derived from subsurface temperature data, including 24 high-resolution static temperature logs from the North Dakota Geological Survey and a large proprietary dataset (>1,000) of drill stem test (DST) and bottom hole temperatures (BHT) from boreholes throughout Montana and North Dakota provided by IHS Markit ® (2022). This grid is applied in the model from time steps 542 Ma to 97 Ma and again from 43 Ma to 0 Ma. The “BHF050_BasalHeatFlow_Laramide.asc” grid is transformed from the “BHF000_BasalHeatFlow_Calib.asc” grid by -10 mW/m2. The “BHF050_BasalHeatFlow_Laramide.asc” grid is applied from time steps 90 Ma to 50 Ma. The model interpolates time steps between assigned basal flow conditions.

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.

The subsurface temperature grids are results/outputs from the 3D petroleum systems model. They represent modern subsurface temperatures in degrees Fahrenheit extracted onto the stratigraphic horizons in the model. The temperature values are calibrated using 24 high-resolution static temperature logs provided by the North Dakota Geological Survey and a large proprietary dataset (>1,000) of drill stem test (DST) and bottom hole temperatures (BHT) from boreholes throughout Montana and North Dakota provided by IHS Markit ® (2022).

A 3D petroleum systems model requires that the temperature at the sediment surface be defined at each geological time step. Generally, surface temperature can be modeled from paleo-elevation or paleo-water depth history, as well as the paleo-latitude of the basin and global climate patterns through time. The PetroMod software, from which the 3D petroleum systems model was generated, uses the Sediment-Water Interface Temperature (SWIT) tool to help define these boundary conditions. In most time steps, the model assumes that paleo-water depth/elevation was flat and uniform across the basin. In these time steps, surface temperatures in the model do not vary across the basin and are determined by the paleo-latitude (taken at the center of the basin) and the global mean temperatures at sea level. In ten other time steps, however, the model considers variations in paleo-water depth. These ten cases are defined in ASCII grids that show variations in surface temperature, measured in degrees Fahrenheit, in response to paleo-water depth, paleo-latitude, and mean global temperature at the given time step.

This data release contains data associated with the journal article "Modeling the maturation history of the stacked petroleum systems of the Williston Basin, USA". Collectively, the data release includes 13 child items and metadata files that provide detailed descriptions of the attributes, processing steps, and original data sources. There is also a data table, "Williston_Basin_Data_Release_Overview.csv" that describes how all the child items are linked with one another.

This data release contains data associated with the Lewis Shale-Fox Hills Sandstone-Lance Formation depositional system (also referred to as the Lewis Shale system) in the eastern part of the Southwestern Wyoming Province of Wyoming and Colorado. Specifically, the data cover the Great Divide, Washakie, and Sand Wash Basins, the Wamsutter and Cherokee arches, and the Rock Springs Uplift. The Lewis Shale is underlain by the Almond Formation, overlain by the Fox Hills Sandstone, and interfingers with both formations on a regional scale. The Lewis Shale is divided into a lower, informal member, a middle, formal Dad Sandstone Member, and an upper, informal member. At the top of the lower Lewis member, there is a maximum flooding surface informally known as the Asquith marker. Additionally, within the Lewis Shale, there are 15 regional flooding surfaces (F01-F15) that bound and define 15 clinothems (C01-C15). Collectively, the data release includes 18 gross isopach grids, 15 net sand isopach grids, 2 structure grids, 1 data table, and 1 type log image of the Lewis Shale and associated strata. See the associated metadata files for the child data elements and the larger work of Hearon (in review) for detailed descriptions of the geology and additional methods.

These data tables describe the inputs and parameters for the 3D petroleum systems model. This section of data is included for users wishing to rebuild the 3D basin model from scratch, either in PetroMod or another basin modeling software package. All inputs and settings for model construction are included. Settings summaries are provided in a data bundle of comma-separated value (CSV) tables. Also included is the “Williston_Basin_model_inputs_glossary.csv” data table that provides a brief description of all the columns/value fields in the data bundle.
