USGS Publication: Scientific Investigations Report 2013–5131In an attempt to determine if this scale of deformation is detectable with conventional wireline logs, petrophysical properties (primarily mineralogy and porosity) were measured by interpretation of gamma-ray and bulk-density logs. The results of performing a statistical correlation of wireline logs from nine wells indicated that there are discontinuities within the Millboro Shale (undifferentiated Marcellus Shale and Mahantango Formation) where there are significant thickness differences between wells.

In this study, we assess whether disposal practices from treatment of produced waters from both shale gas and conventional operations in Pennsylvania could result in the accumulation of associated alkali earth elements. The results from our 5 study sites indicate that there was no increase in concentrations of total Ra (Ra-226) and extractable Ba, Ca, Na, or Sr in fluvial sediments downstream of the discharge outfalls (p > 0.05) of publicly owned treatment works (POTWs) and centralized waste treatment facilities (CWTs).

Multivariate compositional data analysis methods were used to investigate geochemical data for water injected during hydraulic fracturing and for water produced from 19 Marcellus Shale gas wells in the northern Appalachian Basin.

USGS Publication: Open-File Report 2012–1205
This map sheet with accompanying Geographic Information System (GIS) project is an update of the existing U.S. Geological Survey (USGS) Conterminous U.S. Coal Fields map. This update was compiled using data primarily from the USGS National Coal Resource Assessment (NCRA) and information from other published maps.

Outside Publication: Mathematical GeosciencesMathematicians and geochemists have long realized that compositional data intrinsically exhibit a structure prone to spurious and induced correlations. This paper demonstrates, using the Na–Cl–Br system, that these mathematical problems are exacerbated in the study of sedimentary basin brines by such processes as the evaporation or dissolution of salts owing to their high salinities.

USGS Publication: Scientific Investigations Map 3214
This publication presents a thermal maturity map of Devonian shale in the Illinois, Michigan, and Appalachian basins. The map shows outlines of the three basins (dashed black lines) and an outline of Devonian shale (solid black lines).

Press Release & Publication
The Utica Shale contains about 38 trillion cubic feet of undiscovered, technically recoverable natural gas (at the mean estimate) according to the first assessment of this continuous (unconventional) natural gas accumulation by the U. S. Geological Survey. The Utica Shale has a mean of 940 million barrels of unconventional oil resources and a mean of 208 million barrels of unconventional natural gas liquids.

USGS Publication: Open-File Report 2012–1194Detailed and reconnaissance field mapping and the results of geochemical and mineralogical analyses of outcrop samples indicate that the Devonian shales of the Broadtop Synclinorium from central Virginia to southern Pennsylvania have an organic content sufficiently high and a thermal maturity sufficiently moderate to be considered for a shale gas play.

USGS Publication: Open-File Report 2012–1151
The Organic Petrology Laboratory (OPL) of the U.S. Geological Survey (USGS) Eastern Energy Resources Science Center in Reston, Virginia, contains several thousand processed coal sample materials that were loosely organized in laboratory drawers for the past several decades.
The Appalachian Basin Region is a physiographic province extending from Alabama to Maine and encompasses the eastern seaboard of the United States. Evidence suggests the complex geology of the region was formed by a series of continental plate collisions and deformation resulting in the Appalachian Mountains and large areas of elongated, faulted, and deformed ridges and valleys. Over time erosion has carried sediments seaward to the continental shelf and modified the landscape to the more familiar piedmont terraine. The region contains large amounts of natural resources and a long history of oil, gas, and coal production. The first oil wells in the U.S. were discovered in this province and research and assessments continue on these prolific coal and oil and gas deposits. This web site provides access to the diverse Energy Resources Program research activities and products within the Appalachian Basin Region.
The USGS has completed several assessments of the Appalachian Basin. This information is summarized on the Oil and Gas Assessment Appalachian Basin page.
The National Coal Resource Assessment (NCRA) project was a multi-year effort by the U.S. Geological Survey (USGS) Energy Program to identify, characterize, and assess the coal resources that will supply a major part of the Nation’s energy needs during the next few decades. NCRA data and publications are available on the NCRA Appalachian Basin page.
There are coalbed methane assessments for the Appalachian Basin currently available.
