USGS Publication: Open-File Report 2015-1061
Reconnaissance field mapping and outcrop sampling for geochemical and mineralogical analyses indicate that the Middle Devonian Marcellus Shale in the Broadtop synclinorium and nearby areas from southeastern West Virginia to south-central Pennsylvania has an organic content sufficiently high and a thermal maturity sufficiently moderate to be considered for a shale gas play...

USGS News Release & Publications
Two new USGS publications that highlight historical hydraulic fracturing trends and data from 1947 to 2010 are now available. This national analysis of data on nearly 1 million hydraulically fractured wells and 1.8 million fracturing treatment records from 1947 through 2010 is used to identify hydraulic fracturing trends in drilling methods and use of proppants (sand or similar material suspended in water or other fluid to keep fissures open), treatment fluids, additives, and water in the United States.

Outside Publication: AAPG Bulletin
The number of Marcellus Shale gas wells drilled in the Appalachian basin has increased rapidly over the past decade, leading to increased interest in the highly saline water produced with the natural gas which must be recycled, treated, or injected into deep disposal wells. New geochemical and isotopic analyses of produced water for 3 time-series and 13 grab samples from Marcellus Shale...

USGS Publication: Data Series 868
Comprehensive, published, and publicly available data regarding the extent, location, and character of hydraulic fracturing in the United States are scarce. The objective of this data series is to publish data related to hydraulic fracturing in the public domain. The spreadsheets released with this data series contain derivative datasets aggregated temporally and spatially from the commercial and proprietary IHS database of U.S. oil and gas production and well data (IHS Energy, 2011)...
USGS Publication: Scientific Investigations Report 2014-5131
Hydraulic fracturing is presently the primary stimulation technique for oil and gas production in low-permeability, unconventional reservoirs. Comprehensive, published, and publicly available information regarding the extent, location, and character of hydraulic fracturing in the United States is scarce...

Outside Publication: International Journal of Coal Geology
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 releases new Frequently Asked Questions (FAQs) on Hydraulic Fracturing ("Fracking"). A new Hydraulic Fracturing Website and Multimedia Gallery are also now online.
Hydraulic fracturing, informally referred to as “fracking,” is an oil and gas well development process that typically involves injecting water, sand, and chemicals under high pressure into a bedrock formation via the well. This process is intended to create new fractures in the rock as well as increase the size, extent, and connectivity of existing fractures. Hydraulic fracturing is a well-stimulation technique used commonly in low-permeability rocks like tight sandstone, shale, and some coal beds to increase oil and/or gas flow to a well from petroleum-bearing rock formations. A similar technique is used to create improved permeability in underground geothermal reservoirs.
The Energy Resources Program (ERP) continually updates its oil and gas resource assessments for the United States and the world that includes the USGS National Oil and Gas Assessment (NOGA). NOGA provides information for a number of uses, including the development of domestic energy policies and the formulation of reasonably foreseeable development scenarios and resource management plans for multiple Federal land- and resource-management agencies. Here are just a few basins that include unconventional gas (shale gas, tight gas and coal bed methane) associated with hydraulic fracturing:

Researchers in the Energy Resources Program and colleagues are also actively engaged in examining several aspects related to characterization, use, and impact of produced waters. From the Energy Resources Program fact sheet (Fact Sheet 2010–3100):
"Development and production of oil and gas resources can also require and yield significant quantities of water. Produced water and fluids used and recovered during hydrofracturing (hydrofracing) are likely to play an expanding role in energy resource considerations because treatment and disposal costs for produced and hydrofracing waters vary markedly. Also, the potential beneficial use of produced waters is an area of expanding interest, particularly in areas with limited water resources. The USGS conducts research to provide information on the volume, quality, impacts, and possible uses of water produced during oil, gas, and coalbed methane production and development in the United States."

More research on hydraulic fracturing is underway by a number of USGS offices including the Energy Resources Program, Water Resources, Natural Hazards and Environmental Health. This includes a major study conducted by the U.S. Environmental Protection Agency. The USGS has a large role in a recent Memorandum of Agreement among the Department of the Interior, the Department of Energy, and the Environmental Protection Agency to improve our scientific understanding of the environmental issues related to unconventional oil and gas.
The accurate and unbiased scientific data provided by the U.S. Geological Survey are crucial to the Federal, and State resource managers to meet the challenge of balancing America’s needs for unconventional resources and a clean and healthy environment.
