Low biomass microbiology samples collected from a hydraulically fractured well producing from the Niobrara Shale in Colorado Low biomass microbiology samples collected from a hydraulically fractured well producing from the Niobrara Shale in Colorado
Low biomass waters provide a unique challenge in the field of microbial ecology. It is difficult to determine, when biomass concentrations are extremely low, whether or not the sequencing data received are of good quality and representative of the waters sampled. Fifty-nine samples including 8 blanks were collected from a low biomass hydraulically fractured well producing from the...
Estimates of mineral abundances based on Rietveld refinement of X-ray diffraction data from mill tailings and other ore processing materials Estimates of mineral abundances based on Rietveld refinement of X-ray diffraction data from mill tailings and other ore processing materials
This worksheet displays the results of mineral abundance estimates based on Rietveld refinement of X-ray diffraction (XRD) analyses of mill tailings and other ore processing materials from worldwide localities. Data are also provided to show variation in mineral abundance estimates for subsplits in individual samples. Samples were analyzed using a PANalytical X'Pert Pro diffractometer...
Direct Trace Element Determination in Oil and Gas Produced Waters with Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES): Advantages of High Salinity Tolerance (2019) Direct Trace Element Determination in Oil and Gas Produced Waters with Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES): Advantages of High Salinity Tolerance (2019)
Waters co-produced during petroleum extraction are the largest waste stream from oil and gas development. Reuse or disposal of these waters is difficult due both to their high salinities, which can greatly exceed 35 g/L (seawater equivalent), and also the sheer volume of wastewater generated, which is estimated at nearly 900 billion gallons per year across the United States. Beyond...
Organic Analysis of Oilfield Wastewater from the Williston Basin, North Dakota Organic Analysis of Oilfield Wastewater from the Williston Basin, North Dakota
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...

This source code (T2CPI) is to accompany the paper "Modeling Geologic Sequestration of CO2 in a Deep Saline Carbonate Reservoir with T2CPI, a New Tool for Reactive Transport Modeling" published in Environmental Geosciences.
Oil-source rock correlation studies in the unconventional Upper Cretaceous Tuscaloosa marine shale petroleum system, Mississippi and Louisiana, USA (2019) Oil-source rock correlation studies in the unconventional Upper Cretaceous Tuscaloosa marine shale petroleum system, Mississippi and Louisiana, USA (2019)
The U.S. Geological Survey assessed undiscovered unconventional hydrocarbon resources reservoired in the Upper Cretaceous Tuscaloosa marine shale (TMS) of southern Mississippi and adjacent Louisiana in 2018. As part of the assessment, oil- source rock correlations were examined in the study area where operators produce light (38-45 degrees API), sweet oil from horizontal, hydraulically...
Data from Nanoscale Molecular Fractionation of Organic Matter within Unconventional Petroleum Source Beds (2019) Data from Nanoscale Molecular Fractionation of Organic Matter within Unconventional Petroleum Source Beds (2019)
Fractionation of petroleum during migration through sedimentary rock matrices has been observed across lengths of meters to kilometers. Selective adsorption of specific chemical moieties at mineral surfaces and/or the phase behavior of petroleum during pressure changes are typically invoked to explain this behavior. Given the current emphasis on unconventional (continuous) resources...
Geospatial Data for a Preliminary GIS Representation of Deep Coal Areas for Carbon Dioxide Storage in the Contiguous United States and Alaska Geospatial Data for a Preliminary GIS Representation of Deep Coal Areas for Carbon Dioxide Storage in the Contiguous United States and Alaska
These geospatial data and their accompanying report outline many areas of coal in the United States beneath more than 3,000 ft of overburden. Based on depth, these areas may be targets for injection and storage of supercritical carbon dioxide. Additional areas where coal exists beneath more than 1,000 ft of overburden are also outlined; these may be targets for geologic storage of carbon...
USGS Gulf Coast Petroleum Systems and National and Global Oil and Gas Assessment Projects-Louisiana-Mississippi Salt Basins and Western Gulf Provinces, Upper Cretaceous Tuscaloosa Marine Shale Assessment Unit Boundaries and Assessment Input Data Forms USGS Gulf Coast Petroleum Systems and National and Global Oil and Gas Assessment Projects-Louisiana-Mississippi Salt Basins and Western Gulf Provinces, Upper Cretaceous Tuscaloosa Marine Shale Assessment Unit Boundaries and Assessment Input Data Forms
This data release contains the boundaries of assessment units and input data for the assessment of undiscovered gas hydrate resources on the north slope of Alaska. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total...
Bureau of Land Management's Land and Mineral Legacy Rehost System (LR2000) Mineral Use Cases for the Sagebrush Mineral Resource Assessment, Idaho, Montana, Nevada, Oregon, Utah, and Wyoming Bureau of Land Management's Land and Mineral Legacy Rehost System (LR2000) Mineral Use Cases for the Sagebrush Mineral Resource Assessment, Idaho, Montana, Nevada, Oregon, Utah, and Wyoming
In 2015, approximately 10 million acres of Federal lands across six western states were proposed for withdrawal from mineral entry by the Bureau of Land Management (BLM) in order to conserve habitat critical for the greater sage-grouse. As a result, the U.S. Geological Survey (USGS) launched the Sagebrush Mineral Resource Assessment (SaMiRA) project in late-2015 to provide BLM with an...
Geochemical characterization of solid media from three watersheds that transect the basal contact of the Duluth Complex, northeastern Minnesota Geochemical characterization of solid media from three watersheds that transect the basal contact of the Duluth Complex, northeastern Minnesota
To document regional water quality in areas of potential base-metal mining, bedrock, soil, streambed sediment, and surface-water samples were collected and analyzed in three watersheds that cross the basal part of the Duluth Complex (northeastern Minnesota). The three watershed each had different mineral-deposit settings: (1) copper-nickel-platinum group element mineralization (Filson...
Chemistry, morphology, modal mineralogy, and photomicrographs of amphiboles and other minerals in the Ironwood Iron-Formation, Gogebic Iron Range, Wisconsin, USA Chemistry, morphology, modal mineralogy, and photomicrographs of amphiboles and other minerals in the Ironwood Iron-Formation, Gogebic Iron Range, Wisconsin, USA
The Ironwood Iron-Formation, part of the Gogebic Iron Range in Wisconsin, is a Paleoproterozoic Superior-type banded iron formation (BIF) with substantial iron resource potential. The development of a Mesoproterozoic contact metamorphic aureole related to the emplacement of the Mellen Intrusive Complex resulted in the production of a variety of silicate minerals in the western portion of...
