In situ recovery (ISR) uranium mining is a technique in which uranium is extracted by a series of injection and recovery wells developed in a permeable sandstone host rock. Chemical constituents (lixiviants) are added to groundwater injection wells to mobilize uranium into groundwater. Before mining, baseline water quality is measured by sampling groundwater from the aquifer intended to be mined and over and underlying units over a geographic area that reflects the proposed mine location. After mining, groundwater is restored using a variety of techniques intended to return groundwater quality to as close to baseline as practicable. After groundwater has been restored, groundwater quality is monitored to determine...

In 2013 the U.S. Geological Survey (USGS) drilled and logged a continuous core located on the northeast flank of the Alcova anticline in the southeastern part of the Wind River Basin, Wyoming to evaluate the source rock potential of the Lower and lowermost Upper Cretaceous marine shales (fig. 1). The well, named the Alcova Reservoir AR–1–13, was spud in the lower part of the Frontier Formation and ended in the upper part of the Cloverly Formation, and recovered core between 40.5 feet (ft) and 623 ft (figs. 1, 2). After coring was completed the USGS recorded geophysical data from the well bore, with digital data collected to a depth of 622 ft. Data include natural gamma, resistivity, conductivity, density, sonic,...

The Bighorn Basin is a large Laramide structural and sedimentary basin that encompasses about 10,400 square miles in north-central Wyoming and south-central Montana (fig. 1). The basin is bounded on the northeast by the Pryor uplift, on the east by the Bighorn uplift and on the south by the Owl Creek uplift. The northern margin is formed by a zone of faulting and folding referred to as the Nye-Bowler lineament. The western and northwestern margins are formed by the Absaroka volcanics and Beartooth uplift, respectively. Commercial hydrocarbon production was first established in the Bighorn Basin when oil was discovered from Cretaceous reservoirs at Garland field in 1906 (Biggs and Espach, 1960). Since then, many...

The Wind River Basin is a structural and sedimentary basin that formed during the Laramide orogeny in latest Cretaceous and early Eocene time. The basin encompasses about 7,400 square miles in central Wyoming and is bounded by the Washakie, Owl Creek and Bighorn uplifts on the north, the Casper arch on the east, the Granite Mountains uplift on the south, and Wind River uplift on the west (fig. 1). Many important conventional and unconventional oil and gas resources have been discovered and produced from reservoirs ranging from Mississippian through Tertiary in age (Keefer, 1969; Fox and Dolton, 1989, 1996; De Bruin, 1993; Johnson and others, 1996, 2007). It has been suggested by numerous authors (Geis, 1923; Schrayer...
This data release includes biomarker ratio values calculated from measurements made at the USGS for the reference oil NSO-1 that were reported in a journal article entitled Comparability and reproducibility of biomarker ratio values measured by GC-QQQ-MS (French et al., 2020).

The input form provides a record of the complete input values required for the quantitative assessment of water and proppant associated with oil and gas production for the continuous oil and gas resource in a geologically defined Assessment Unit, and the same form template is used for all such assessments. Each USGS water and proppant assessment builds from a USGS petroleum assessment that provides the geologic foundation for the water and proppant assessment. Assessment units are defined in the course of conducting the petroleum assessment.

The Wind River Basin is a large Laramide (Late Cretaceous through Eocene) structural and sedimentary basin that encompasses about 7,400 square miles in central Wyoming (fig. 1). The basin is bounded by the Washakie Range and Owl Creek and southern Bighorn Mountains on the north, the Casper arch on the east, the Granite Mountains on the south, and Wind River Range on the west (fig. 1). Many important conventional and unconventional oil and gas resources have been discovered and produced from reservoirs ranging from Mississippian through Tertiary in age (Keefer, 1969; Fox and Dolton, 1989, 1996; De Bruin, 1993; Johnson and others, 1996, 2007). It has been suggested by numerous authors including: Keefer, 1969; Meissner...

Thirty-nine samples were selected to evaluate the source rock potential of the marine shales in the cored interval as determined by total organic carbon (TOC) and programmed pyrolysis analysis. Five samples are from the lower part of the Frontier...

Grade and tonnage data for calcrete-type surficial uranium deposits found in 11 different countries were compiled. Fifty-eight deposits with reported grade and tonnage, and thirty-five occurrences for which there is no reported resource are tabulated in separate Excel workbook spreadsheets.

Petroleum source rocks deposited during Cenomanian – Turonian time (late Cretaceous) are major generators of continuous and conventional oil and gas resources in the Gulf of Mexico Basin. The Eagle Ford Shale is a particularly important petroleum system and represents a substantial fraction of total oil and gas production in the United States. Significant lateral and vertical geochemical and mineralogical variability have been identified in previous studies of the Eagle Ford Shale, but most recent work has focused on the area of the play southwest of the San Marcos Arch. As part of a larger USGS coring program to examine important continuous oil and gas plays in the Texas-Gulf Coast region, the USGS Gulf Coast Petroleum...

Major-element and trace-element concentrations in 76 core samples and seven surface samples of rocks from the Coles Hill uranium deposit and vicinity, Pittsylvania County, south-central Virginia are presented as tabular digital data. The Coles Hill deposit is the largest unmined uranium deposit in the United States. The data were collected to 1) characterize the chemistry of variably uranium-mineralized rock units within the deposit and 2) to compare with the chemistry of un-mineralized surface exposures of the same rock units. Cores were sampled in 2017 by U.S. Geological Survey (USGS) personnel from archived historical collections of the Virginia Museum of Natural History. Core samples were selected based on measurable...

Cell maps are created by the USGS as a method for illustrating the degree of petroleum exploration, type of production as indicated by final well status, distribution of production and well density in a given area; in this case, covering the SaMiRa project area of interest. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether oil and gas wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, dry or the type of production of the wells located within the cell is unknown. The well information was initially retrieved from the IHS Energy Enerdeq, which is a proprietary, commercial database containing information...
