In 2020, the U.S. Geological Survey (USGS) assessed the potential for undiscovered, technically recoverable continuous (unconventional) oil and gas resources in the Mowry Shale in the Wind River Basin Province (Finn and others, 2021). To better characterize the source rock potential of the Mowry Shale and associated strata, 129 samples were collected from 45 wells from the well cuttings collection stored at the USGS Core Research Center in Lakewood, Colorado. The sampled wells are located along the margins of the basin in order to obtain samples that were not subjected to the effects of deep burial and subsequent organic carbon loss due to thermal maturation (Daly and Edman, 1987) (fig. 1). One hundred samples are...

In 2006, Rock Well Petroleum drilled and logged nearly 1,600 feet (ft) of continuous core on the southern part of the Casper arch in Natrona County, Wyoming (see fig1.png). The core hole, named the Poison Spider core #8 penetrated the interval extending from the Upper Cretaceous Frontier Formation to the Triassic Alcova Limestone. The core was subsequently donated to the U.S. Geological Survey Core Research Center (CRC) in Lakewood, Colorado, where it was sampled to evaluate the hydrocarbon source rock potential of the Lower and lowermost Upper Cretaceous marine shales.

In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project. One of the major goals of the NAWQA project was to determine how river water quality has changed over time. To support that goal, long-term consistent and comparable monitoring has been conducted by the USGS on streams and rivers throughout the Nation. Outside of the NAWQA project, the USGS and other Federal, State, and local agencies also have collected long-term water-quality data to support their own assessments of changing water quality. In 2017, data from these multiple sources were combined to support one of the most comprehensive assessments...

Patrick Bayou, a section of the Houston Ship Channel near Deer Park, Texas, has accumulated permitted industrial wastewater discharges, municipal wastewater treatment plant effluent, and stormwater runoff from adjacent industrial facilities and nearby urban and residential areas. These discharges are suspected to be the primary sources of the sediment contamination in the Patrick Bayou section of the Houston Ship Channel near Deer Park, Texas. The U.S. Environmental Protection Agency (EPA) placed Patrick Bayou on the Superfund program’s National Priorities List because of sediment contamination detected in the wetlands bordering Patrick Bayou, posing a threat to downstream fisheries. The U.S. Geological Survey (USGS),...

This dataset contains estimated total organic carbon (TOC) calculated using the delta log R (dlogR) method, developed by Passey and others (1990), within BasinMod modeling software for the Tuscaloosa marine shale (TMS) in southwestern Mississippi, U.S.A. BasinMod is a modeling software developed by Platte River Associates, Inc. Using version 2021-03-03 of the software, sonic and resistivity logs and a background TOC of 0.8 weight percent were used to calculate dlogR TOC in the TMS high resistivity zone (HRZ) after baselining these two log curves in a non-source rock interval within the TMS. Due to variable mineralogy between the upper and lower sections of the TMS, two baselines were selected to determine whether...

A U.S. Geological Survey (USGS) provisional geochemical and mineralogical database for hydrocarbon-rich shale in the Appalachian region has been compiled by Catherine Enomoto, Frank Dulong and Robert Milici for online distribution. USGS staff collaborated with geologists in State geological agencies to obtain samples that were analyzed for organic properties, including Rock Eval analyses, total organic carbon (TOC), thermal maturity, and semi-quantitative mineralogy. However, the database also contains previously published data, with appropriate citations included. Previously unpublished data are from samples collected and analyzed between 2007 and 2012 from wells drilled between 1931 and 2009, and from exposures...

This compilation presents total organic carbon and pyrolysis analysis data for the Pierre Shale, Niobrara Formation, and other Cretaceous marine shales in the Raton Basin-Sierra Grande Uplift Province. The data was used to characterize these potential source rock intervals in support of the oil and gas resource assessment in the province. The data was compiled from the publicly available files at the USGS Core Research Center in Lakewood, Colorado and from published literature.

This data release contains programmed pyrolysis, organic petrographic (reflectance), and semiquantitative X-ray diffraction mineralogy data for subsurface coal and shale samples from around the world. Samples were subjected to hydrous or anhydrous pyrolysis experiments at varying temperatures and the resulting residues were analyzed via programmed pyrolysis and reflectance to document changes in thermal maturity.

The U.S. Geological Survey assessed undiscovered petroleum resources in the downdip Paleogene formations of the U.S. Gulf Coast in 2018. During the assessment new data and information were collected to evaluate thermal maturity, source rock character, and unconventional reservoir rock prospectivity for the Cenozoic-aged section in south Louisiana. Samples were analyzed using multiple analytical approaches, including programmed pyrolysis (Rock-Eval), Leco TOC, organic petrographic analysis including vitrinite reflectance (Ro, %), and X-ray diffraction mineralogy.

In 2013 the U.S. Geological Survey (USGS) drilled a continuous core 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 . The well, named the Alcova Reservoir AR–1–13, located on the northeast flank of the Alcova anticline was spud in the lower part of the Frontier Formation and ended in the upper part of the Cloverly Formation recovered core between 40.5 feet (ft) and 623 ft. 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...

In 2021 the United States Geological Survey (USGS) sampled the lower part of the Upper Cretaceous Lewis Shale in the eastern part of the Southwestern Wyoming Province to better characterize its petroleum source rock potential for an upcoming resource assessment. Ninety-five samples from 24 wells were collected from well cuttings of the lower part of the Lewis Shale stored at the U.S. Geological Survey Core Research Center in Lakewood, Colorado. The selected wells are located near the shallow margins of the basin to obtain samples that were not subjected to the effects of deep burial and subsequent organic carbon loss due to thermal maturation as described by Daly and Edman (1987) (fig, 1). The sample intervals were...

Total carbon and nitrogen concentrations, and delta carbon-13 and delta nitrogen-15 stable isotope ratios, were determined in sediment samples to potentially identify the sources of organic matter in the sediment and any post-depositional diagenetic alteration of the organic matter over time.

This data release contains Rock-Eval pyrolysis, organic petrographic (reflectance), and X-ray diffraction mineralogy data for subsurface Mesozoic rock samples from the eastern onshore Gulf Coast Basin (primarily Mississippi and Louisiana). Samples were analyzed in support of the U.S. Geological Survey (USGS) assessment of undiscovered petroleum resources in the Upper Cretaceous Tuscaloosa marine shale and evaluation of shale gas prospectivity in the Aptian section of the Mississippi Salt Basin.
