Petroleum within unconventional source-rock reservoirs is hosted in organic matter and mineral pore space as well as in voids and microfractures. Recent work has shown that for source-rock reservoirs in the dry gas window, significant portions of methane (CH4), the main component of petroleum at elevated maturities, can be stored within fine organic matter porosity. However, within reservoirs at lower thermal maturities (e.g., peak oil or wet-gas conditions), the distribution and behavior of CH4 and the higher alkanes that comprise gas condensates across pore sizes is unclear, especially for fine pores with diameters <50 nm. Understanding CH4 within these settings provides insight for petroleum generation, movement,...

The Appalachians are a landscape filled with globally-significant biological diversity and cultural resources that provides essential benefits to large cities and surrounding human communities. The region is also rich in energy resources that meet national and regional demands for energy. As wind, natural gas, and oil energy development expand along with traditional coal, there is an increasing need for research to inform discussions on how to meet immediate and future energy needs while sustaining the health of natural systems. To help address this need, the Appalachian LCC awarded a grant to The Nature Conservancy to assess current and future energy development across the entire region. Assessing Future Energy...

The geology of an area of 660 square miles mostly in the northeastern corner of Tennessee and small adjacent areas in Virginia and North Carolina is the subject of this report. The region lies principally in the Unaka province, with extensions northwestward into the Appalachian Valley and southwestward into the Blue Ridge province. The report combines results of surveys made between 1941 and 1953 by the U. S. Geological Survey, the Tennessee Division of Geology, and the Tennessee Valley Authority, and is published in cooperation with the Tennessee Division of Geology. Northeasternmost Tennessee is a region of widespread mineralization and was formerly important for mineral production. Iron, manganese, and bauxite...
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...

The Appalachian Landscape Conservation Cooperative (LCC) provided a grant to Cornell University Environmental Engineers to study how the region’s surface freshwater supply and the health of natural systems delivering this resource have been impacted and may be altered in the coming years under increasing water withdrawals.The research focuses on the Marcellus Shale region in the Central Appalachians, including portions of New York, Pennsylvania, Ohio, Maryland, West Virginia, and Virginia. In addition to considering the cumulative impacts of water withdrawals, the researchers looked at specific impacts of large water withdrawals with hydraulic fracturing in the Marcellus Shale region as one example.Datasets include...

The Blue Ridge belt in northwestern North Carolina and northeastern Tennessee is composed chiefly of 1,000-million to 1,100-million-year-old metamorphic and plutonic rocks that have been thrust many miles northwestward across unmetamorphosed Cambrian(?) and Cambrian sedimentary rocks of the Unaka belt. The Blue Ridge thrust sheet is rooted on the southeast along the Brevard zone, a zone of strike-slip faulting along which metamorphic and plutonic rocks of the Inner Piedmont belt are juxtaposed with rocks of the Blue Ridge. Near the southeastern edge of the Blue Ridge belt, the Blue Ridge thrust sheet is breached by erosion, and the rocks beneath are exposed in the Grandfather Mountain window, which is 45 miles long...
