New Geological Compilation Available for Resource Studies and Land-Use Planning
Appalachian coal and petroleum resources are still available in sufficient quantities to contribute significantly to fulfilling the nation’s energy needs, according to a recent study by the U.S. Geological Survey.
Appalachian coal and petroleum resources are still available in sufficient quantities to contribute significantly to fulfilling the nation’s energy needs, according to a recent study by the U.S. Geological Survey.
The Appalachian basin, which includes the Appalachian coalfields and the Marcellus Shale, covers parts of Alabama, Georgia, Kentucky, Maryland, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia and West Virginia.
“The study we conducted is a modern, in-depth collection of reports, cross sections and maps that describe the geology of the Appalachian basin and its fossil fuel resources,” said USGS scientist Leslie Ruppert, the study’s lead editor.
Petroleum resources, including oil and natural gas, remain significant in the Appalachian basin. Although both conventional oil and gas continue to be produced in the Appalachian basin, most new wells in the region are drilled in shale reservoirs, such as the famous Marcellus and Utica Shale, to produce natural gas.
The Appalachian basin contains significant coalbed methane and high-quality, thick, bituminous coal resources although the resource is deeper and thinner than the coal that has already been mined.
Although this volume is not a quantitative assessment of all notable geologic and fossil fuel localities in the Appalachian basin, the selected study areas and topics presented in the chapters pertain to large segments of the basin and a wide range of stratigraphic intervals. This updated geologic framework is especially important given the significance of shale gas in the basin.
This volume discusses the locations of coal and petroleum accumulations, the stratigraphic and structural framework, and the geochemical characteristics of the coal beds and petroleum in the basin, as well as the results of recent USGS assessments of coal, oil and gas resources in the basin.
Many of the maps and accompanying data supporting the reports in this volume are available from chapter I.1 as downloadable geographic information system (GIS) data files about the characteristics of selected coal beds and oil and gas fields, locations of oil and gas wells, coal production, coal chemistry, total petroleum system (TPS) boundaries and bedrock geology. Log ASCII Standard (LAS) files for geophysical (gamma ray) wireline well logs are included in other chapters.
USGS is the only provider of publicly available estimates of undiscovered technically recoverable oil and gas and coal resources of onshore lands and offshore state waters. This study of the Appalachian basin will underpin energy resource assessments and may be found online.
