Lithium observations, machine-learning predictions, and mass estimates from the Smackover Formation brines in southern Arkansas
Global demand for lithium, the primary component of lithium-ion batteries, greatly exceeds known supplies and this imbalance is expected to increase as the world transitions away from fossil fuel energy sources. The goal of this work was to calculate the total lithium mass in brines of the Reynolds oolite unit of the Smackover Formation in southern Arkansas using predicted lithium concentrations f
Carbon Dioxide Storage Resources-Anadarko and Southern Oklahoma Basins: Chapter R. Spatial Data
This data release provides shapefiles that represent storage assessment units (SAUs) and drilling-density cells in the Anadarko and Southern Oklahoma Basins of Colorado, Kansas, Oklahoma, and Texas in the United States. The SAU is the fundamental unit used in the National Assessment of Geologic Carbon Dioxide Storage Resources project for the assessment of geologic CO2 storage resources. The SAU i
Reflectance data from figures in: Using X-ray spectrum of carbon in electron microprobe analysis to determine thermal maturity of organic matter in mudstones
Conventional methods of assessing organic matter (OM) thermal maturity have limitations and often fail to reflect the geochemical heterogeneity between individual organic phases in mudstone samples. Vitrinite and solid bitumen reflectance, for example, is often measured to estimate OM thermal maturity but is restricted to specific types of OM. Alternative methods deserve exploration. This dataset
Evaluation of solid bitumen created from marine oil shale bituminite under hydrous and anhydrous pyrolysis conditions
This study tests the influence of environmental conditions on conversion of the maceral bituminite to a solid petroleum residuum (solid bitumen) during pyrolysis. The presence of water in sedimentary basins controls multiple processes during petroleum generation, migration, and storage. Four organic-rich (26–36 wt.% total organic carbon) oil shale samples were collected from thin-bedded (several c
Carbon Dioxide Storage Resources - Appalachian Basin, Black Warrior Basin, Illinois Basin, and Michigan Basin: Chapter P, Spatial Data
The storage assessment unit (SAU) is the fundamental unit used in the National Assessment of Geologic Carbon Dioxide Storage Resources project for the assessment of geologic CO2 storage resources. The SAU is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the assessment interval. Individual SAUs are defined on the basis of common geologic and h
Utica Shale and Point Pleasant Formation Isotopic Compositions
This release contains isotopic composition (δ7Li, δ11B, δ138Ba) data of produced water and core samples taken from the Utica Shale and Point Pleasant Formation.
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 standard lab pr
Coal mine drainage effluents and associated solids major, trace, rare earth element and radium concentrations collected from Pennsylvania, USA
Discharges from abandoned coal mines and associated mine wastes represent historic and persistent sources of pollution in the Appalachian Basin, United States. In this study, we conducted the first-ever survey of radium (Ra) in coal mine drainage (CMD) water and solid samples in the United States. Samples were collected from 4 untreated coal mine discharges and 9 treated coal mine discharges (i.e.
National and Global Petroleum Assessment—North Chukchi Basin Province: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables
This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in the North Chukchi Basin. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources. The assessment unit is defi
Shallow Coal Exploration Drill-Hole Data for Arkansas
Shallow (300 ft or less) coal exploration drill-hole data from 692 wells located in Arkansas are provided in this data release. The well locations extend over nine Arkansas counties and were drilled between 1975 and 1977, primarily by Phillips Petroleum Company (Phillips). Also included in the dataset are 79 wells drilled by Tenneco. The data were donated to the U.S. Geological Survey (USGS) in 20
Microscopic Images of Leonardite and Humate Biochar: Using Reflected Light Microscopy in Biochar Characterization
Biochar is a carbon-rich substance that is derived through the thermochemical conversion of biomass. Biochar is recognized for its significance in environmental applications and sustainable agriculture. In an effort to comprehend how the source material and pyrolysis parameters influence its properties, reflected light microscopy is being used to produce microscopic images for analysis of selected
