Insights on using solid bitumen reflectance as a thermal maturity proxy in the Bakken Formation, Williston Basin, USA Insights on using solid bitumen reflectance as a thermal maturity proxy in the Bakken Formation, Williston Basin, USA
To further refine the use of solid bitumen reflectance (BRo in %) as a measurement of thermal maturity in source-rock reservoirs, we examined its relationship to other thermal proxies in the Bakken Formation. Comparisons included criteria from programmed temperature pyrolysis, gas chromatography (GC), and Fourier transform infrared (FTIR) spectroscopy. Thirty-two organic-rich samples...

Evaluation of portable Raman spectroscopic analysis for source-rock thermal maturity assessments on bulk crushed rock Evaluation of portable Raman spectroscopic analysis for source-rock thermal maturity assessments on bulk crushed rock
This study presents a simplified method and empirical relationships for determining organic matter thermal maturity using a portable Raman system equipped with a 785 nm laser, for analysis of crushed, whole-rock samples. Suites of rocks represented by shale and coal samples with various mineralogical composition, thermal maturity, and total organic carbon (TOC) were used to test the...

Reconstructing the paleoceanographic and redox conditions responsible for variations in uranium content in North American Devonian black shales Reconstructing the paleoceanographic and redox conditions responsible for variations in uranium content in North American Devonian black shales
The uranium (U) content, and more recently, the ratio between 238U and 235U in black shales are commonly applied as a proxy to determine redox conditions and infer organic-richness. Uranium contents typically display a linear relationship with total organic carbon (TOC) in shales. This relationship is due to the processes and mechanisms responsible for the incorporation of U into the...

Geochemical data for Illinois Basin coal samples, 2015–2018 Geochemical data for Illinois Basin coal samples, 2015–2018
Researchers at the U.S. Geological Survey (USGS) and their collaborators conducted a study of the geochemical properties of coals currently produced for electric power generation in the Illinois Basin in Illinois and Indiana. The study follows from recommendations by an expert panel for the USGS to investigate the distribution and controls of trace constituents such as mercury (Hg) in...

Rare earth elements in coal and coal fly ash Rare earth elements in coal and coal fly ash
The rare earth elements (REEs) are a group of 17 elements sharing similar chemical properties. They include yttrium (Y, atomic number 39), scandium (Sc, atomic number 21), and the 15 elements of the lanthanide series, atomic numbers 57 (lanthanum, La) to 71 (lutetium, Lu). Because promethium (Pm, atomic number 61) does not occur in the Earth’s crust and scandium typically has different...

Vanadium Vanadium
Vanadium is used primarily in the production of steel alloys; as a catalyst for the chemical industry; in the making of ceramics, glasses, and pigments; and in vanadium redox-flow batteries (VRBs) for large-scale storage of electricity. World vanadium resources in 2012 were estimated to be 63 million metric tons, which include about 14 million metric tons of reserves. The majority of the...

Major, minor, and trace element composition of black shales of the Virginia Formation, Minnesota Major, minor, and trace element composition of black shales of the Virginia Formation, Minnesota
Sixty samples of Paleoproterozoic Virginia Formation of the Animikie Group black shales were collected from two public drill cores (VHD-00-1; LWD-99-2) housed at the Minnesota Department of Natural Resources Drill Core Library in Hibbing, MN. The black shale samples were ground to a powder and subjected to several analyses. Trace elements were determined using multi-acid digestion and...
Total organic carbon and programmed temperature pyrolysis data for the Bakken Formation, Williston Basin, USA Total organic carbon and programmed temperature pyrolysis data for the Bakken Formation, Williston Basin, USA
One hundred ninety-six black shale samples of the Late Devonian-Early Mississippian Bakken Formation were selected from eight drill cores located in Montana and North Dakota, USA. Samples were powdered and total organic carbon and programmed temperature pyrolysis analysis were performed at the U.S. Geological Survey Petroleum Geochemistry Research Laboratory in Denver, CO following...
Screening geochemistry, gas chromatography, and solid bitumen reflectance data in the Bakken petroleum system, Williston Basin, USA Screening geochemistry, gas chromatography, and solid bitumen reflectance data in the Bakken petroleum system, Williston Basin, USA
Thirty-two organic-rich samples from the lower and upper shale members of the Devonian–Mississippian Bakken Formation were collected from eight cores across the Williston Basin, USA, at depths (~7,575–11,330 ft) representing immature through post peak oil/early condensate thermal maturity conditions. Reflectance results were correlated to programmed temperature pyrolysis parameters...
