The U.S. Geological Survey (USGS) collects magnetic susceptibility measurements on in-situ and laboratory rock samples to help identify the sources of anomalies in aeromagnetic surveys in Alaska. Magnetic susceptibility is a measure of how much a material will become magnetized in an applied magnetic field and is the ratio of magnetization, M (magnetic moment per unit volume), to the...

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered conventional oil and gas resources in the Buda limestone reservoir of Texas. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment (NAGA) Project for the assessment of undiscovered oil and gas resources. The assessment unit is...

In 2023, the U.S. Geological Survey conducted a reconnaissance survey of surface-water quality in areas of southern West Virginia and eastern Kentucky that have ongoing and/or historic mountaintop removal mining for coal resources. The water-quality data collected during the survey are collated in this data release.

This data release contains major ion geochemistry (B, Ba, Br, Cl, Ca, Fe, K, Li, Mg, Mn, Na, Si, SO4, Sr) and total dissolved solids measurements from produced water samples collected from petroleum wells in the Paradox and Uinta Basins, Utah. Analyses were conducted at the U.S. Geological Survey laboratories in Reston, Virginia. The release comprises two files: one metadata file and one...

This data release (https://doi.org/10.5066/P13JNYU2) contains neutron scattering intensities of a Niobrara Formation rock sample in the presence of pressurized perdeuterated methane, perdeuterated methane-methane, and perdeuterated methane-ethane mixtures at 60 degrees C. Also provided are the densities and scattering length densities for the various fluid mixtures and modeled accessible...

This data release contains metaproteomics data from subsurface methanogenic communities in an Antrim Shale (Michigan basin, MI) natural gas well. The subsurface microbial communities have interacted with produced waters that were exposed to ambient surficial conditions prior to injection of the produced waters into the well. These data are used in a related publication to understand...

This data release and model archive contains geochemical and microbial reaction modeling input files, selected output files, and an accompanying data dictionary. The files were used to simulate hydrogen consumption during underground hydrogen storage (UHS). Batch-reaction simulations were developed using the React program in Geochemist’s Workbench (GWB) and are based on estimated...

Three round robin exercises (RRE) aimed at characterizing bituminite and testing the reproducibility of random vitrinite (VRo %) and bituminite (BitRo %) reflectance measurements of the Kimmeridge Clay Formation were conducted in 2016, 2018, and 2020. This work was conducted by the Identification of Dispersed Organic Matter Working Group (IDOM WG) of the International Committee for Coal...

The Cretaceous Mowry Shale is a prolific source rock in numerous Laramide basins and operators have recently increased research activity testing the Mowry as an unconventional source-rock resevoir in the Powder River Basin (PRB). Despite this recent increase in research activity, much work remains on characterizing the quantity and quality of oil retained in thermally mature Mowry Shale...

The Neoproterozoic–Early Cambrian Salt Range Formation (SRF) of Pakistan is a sequence of salt, gypsum, marl, dolomite, fine-grained siliciclastic rocks (shale, siltstone and sandstone), oil shale, and hydrothermally altered extrusive volcanics. The formation occurs in the Salt Range physiographic feature, a mountain range rising 750 to 1000 m above alluvial plains of northwestern...

In 2024, the U.S. Geological Survey, in cooperation with Riverside Energy Michigan, LLC, conducted an injection experiment to assess the potential for stimulating biogenic methane in the Mortensen A4-24 well which was completed in the Antrim Shale and located in Antrim County, Michigan, United States of America. Approximately 20 barrels (bbl) of produced water was pumped from the well...

Large Igneous Provinces (LIPs) are associated with dramatic changes to the Earth system; their rapid release of carbon to the surface environment may initiate catastrophic climatic changes that cause mass extinction. This carbon release is often associated with volcanic emissions, yet metamorphic carbon production during LIP events may be substantial. Metamorphic carbon devolatilization...
