Shallow subsurface electrical conductivity was mapped at Stateline National Wildlife Refuge (NWR) in northeast Montana using the DUALEM421 electromagnetic sensor (Dualem, Inc., ON, Canada) in the winter of 2017. Data were acquired by towing the DUALEM421 sensor on a sled behind an all-terrain vehicle or snow machine, with the sensor at a nominal height of 0.3 meters (m) above ground surface. Approximately 3 line-kilometers (km) of data were acquired over an area of approximately .2 square-kilometers. Data were manually edited to remove sensor dropouts, lag corrected for apparent offsets between recorded GPS location and data locations for each coil pair, and averaged to a sounding distance of 1m along the survey...

The organic composition of produced waters (flowback and formation waters) from the Bakken Formation and the Three Forks Formation in the Williston Basin, North Dakota were examined in this study in order to aid in the remediation of surface contamination due to spills during transport and help develop treatment methods for recycling. Twelve produced water samples were collected from wells in the Bakken and Three Forks Formations at the well head and analyzed for non-purgable dissolved organic carbon (NPDOC), acetate, and extractable hydrocarbons. NPDOC and acetate concentrations from sampled wells from ranged from 33-190 milligrams per liter (mg/L) and 16-40 mg/L, respectively. Concentrations of individual extractable...

These metadata sets present the comprehensive geochemical composition of solid and water samples from the site of a 11.4ML (million liters) wastewater spill discovered in January, 2015. Analyses of a pipeline sample (analyses of select analytes), supplied by the North Dakota Department of Health are also included. The spill was near Blacktail Creek, north of Williston, ND. The leak was from a pipeline located approximately 70m from Blacktail Creek. The creek flows 17km before entering the Little Muddy River, a tributary to the Missouri River. The study included samples collected in waters upstream and downstream from Blacktail Creek in February and June 2015, June 2016, and June 2017. These data sets include field...

The data presented includes chloride concentration and specific conductance in surface water collected from 33 wetlands in the Williston Basin of Montana and North Dakota, 2015-2017 as well as count data for three species of amphibians captured at each wetland. Data also includes concentrations of metals in bed sediment and larval amphibians collected from 32 and 12 wetlands, respectively in 2015-2016. Abundance of barred tiger salamanders (Ambystoma mavortium), boreal chorus frogs (Pseudacris maculata), northern leopard frogs (Lithobates pipiens) was estimated at 33 wetlands from 2015-2017. Surface water was collected in the summer from each wetland in 2015-2017 at the same time as the amphibian surveys and analyzed...

Biological endpoints for three focal test species [Daphnia magna (mortality), Psuedacris maculata (mortality, growth, and development), and Lemna gibba (growth)] in response to exposure to reconstituted or field-collected water under laboratory conditions. Field-collected waters were collected from wetlands within the Prairie Pothole Region (PPR) of the United States. Reconstituted water was mixed to mimic some chemistry of surface water from brine contaminated PPR wetlands. Also included are water quality and chemical concentration data from all assays.

Paleo-water depth is an important component of modeling surface temperatures through time. Paleo-water depth values represent the elevation of the sediment-water interface relative to global mean sea level at a particular point in geologic time. In most of the model time steps, paleo-water depth values were treated uniformly (single value) across the modeled area of interest, as a simplifying assumption. Most of the model layers were deposited in marine conditions, where the sediment-water interface was below mean sea level (positive paleo-water depths); however, the ground surface of the Williston Basin is now several thousand feet above sea-level, and the Cenozoic model layers were likely deposited in continental...

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).

The model layer facies grids describe geographic variations in lithology mixtures (facies) used in the 3D petroleum systems model of the Williston Basin. The grids provide constraints on the physical properties used in the model simulation, including mechanical compaction, thermal conductivity, heat capacity, radiogenic heat, porosity and permeability trends, diagenesis, and capillary entry pressures. The grids were derived from borehole geophysical log signatures from two key model layers: the middle member of the Devonian-Mississippian Bakken Formation and the Upper Ordovician Icebox Formation. All the other model layers used a single lithology mixture and were not represented by gridded facies maps. This is a...

This data release includes the model input and output files for the 3D petroleum systems model of the Williston Basin. The model was created in Schlumberger's PetroMod version 2020.1. The enclosed folders are standard PetroMod format and contain all data necessary for defining and re-simulating the model. Please contact Tim Nesheim at the North Dakota Geologic Survey (tonesheim@nd.gov) directly for static temperature log data used in the temperature calibration. Proprietary IHS Markit ® (2022) data used for model calibration are also not included in this data release. This is a child item of a larger data release titled "Data release for the 3D petroleum systems model of the Williston Basin, USA".

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".
