National Assessment of Oil and Gas - Cotton Valley Group and Travis Peak-Hosston Formation Assessment Units, Western Gulf and East Texas Basin and Louisiana-Mississippi Salt Basins Provinces (047, 048 and 049)
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 Petroleum System. The Assessment Unit is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the Total Petroleum System, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type. The Assessment Unit boundary is defined geologically as the limits of the geologic...
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° API), sweet oil from horizontal, hydraulically-fractured wells in an overpressured ‘high-resistivity’ (>5 ohm-m) zone (HRZ) at the base of the TMS. Our initial characterization of TMS samples indicated overall low organic carbon (avg. TOC ~1.0%) and dominance of a gas-prone Type III or mixed Type II/III kerogen, potentially inconsistent with a self-sourced petroleum system model for...
The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, hydrocarbon plays were defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The province boundaries were drawn on the county lines that most closely followed the natural geologic boundaries.
Tops file for the Niobrara interval of the Upper Cretaceous Cody Shale and associated strata in the Bighorn Basin, Wyoming
The Bighorn Basin is a large Laramide structural and sedimentary basin that encompasses about 10,400 square miles in north-central Wyoming and south-central Montana (fig. 1). The basin is bounded on the northeast by the Pryor uplift, on the east by the Bighorn uplift and on the south by the Owl Creek uplift. The northern margin is formed by a zone of faulting and folding referred to as the Nye-Bowler lineament. The western and northwestern margins are formed by the Absaroka volcanics and Beartooth uplift, respectively. Commercial hydrocarbon production was first established in the Bighorn Basin when oil was discovered from Cretaceous reservoirs at Garland field in 1906 (Biggs and Espach, 1960). Since then, many...
XRD data from study on the impact of thermal maturity on shale microstructures using hydrous pyrolysis (2018)
The dataset covers X-ray diffraction (XRD) applied for mineral determination in shales from the Utica, Excello, Niobrara, and Monterey formations. The XRD was performed prior to modified Rock-Eval pyrolysis, reflectance, organic petrology, and Fourier-transform infrared spectroscopy (FTIR) being employed to analyze geochemical properties; gas adsorption (CO2 and N2) was used to characterize pore structures.
ATR data from interaction of kerogen with brine-saturated supercritical carbon dioxide (CO2) and its implications to geologic carbon sequestration and enhanced oil/gas recovery (2018)
The dataset covers Attenuated Total Reflectance (ATR) measurements taken from altered kerogen in shales from the Woodford formation. The ATR measurements were taken after the samples were run through supercritical CO2 alteration experiments in a brine solution.
Tops file for the Niobrara interval of the Upper Cretaceous Cody Shale and associated strata in the Wind River Basin, Wyoming
The Wind River Basin is a large Laramide (Late Cretaceous through Eocene) structural and sedimentary basin that encompasses about 7,400 square miles in central Wyoming (fig. 1). The basin is bounded by the Washakie Range and Owl Creek and southern Bighorn Mountains on the north, the Casper arch on the east, the Granite Mountains on the south, and Wind River Range on the west (fig. 1). Many important conventional and unconventional oil and gas resources have been discovered and produced from reservoirs ranging from Mississippian through Tertiary in age (Keefer, 1969; Fox and Dolton, 1989, 1996; De Bruin, 1993; Johnson and others, 1996, 2007). It has been suggested by numerous authors including: Keefer, 1969; Meissner...
Oil and Gas Wells Data for the Wyoming Landscape Conservation Initiative (WLCI), Southwestern Wyoming
This feature class was created to assemble oil and gas well information for a comprehensive inventory of energy data pertinent to the Wyoming Landscape Conservation Initiative decision-making process. These data are available as online resources for scientists, resource managers engaged in the Initiative, and other researchers. The GIS data and map services created for this study are available for interactive analysis and/or download at the Energy Geoscience Center WLCI website.
Geochemistry data for the USGS Gulf Coast #1 West Woodway core - A thermally immature core of the Eagle Ford Group in central Texas
Petroleum source rocks deposited during Cenomanian – Turonian time (late Cretaceous) are major generators of continuous and conventional oil and gas resources in the Gulf of Mexico Basin. The Eagle Ford Shale is a particularly important petroleum system and represents a substantial fraction of total oil and gas production in the United States. Significant lateral and vertical geochemical and mineralogical variability have been identified in previous studies of the Eagle Ford Shale, but most recent work has focused on the area of the play southwest of the San Marcos Arch. As part of a larger USGS coring program to examine important continuous oil and gas plays in the Texas-Gulf Coast region, the USGS Gulf Coast Petroleum...
