USGS Publication: Open-File Report 2015-1117
The quantities of water and hydraulic fracturing proppant required for producing petroleum (oil, gas, and natural gas liquids) from continuous accumulations, and the quantities of water extracted during petroleum production, can be quantitatively assessed using a probabilistic approach.

Press Release & Publication
The amount of water required to hydraulically fracture oil and gas wells varies widely across the country, according to the first national-scale analysis and map of hydraulic fracturing water usage detailed in a new USGS study accepted for publication in Water Resources Research, a journal of the American Geophysical Union.

Sequestration of CO2 into subsurface reservoirs can play an important role in limiting future emission of CO2 into the atmosphere (e.g., Benson and Cole, 2008). For geologic sequestration to become a viable option to reduce greenhouse gas emissions, large‐volume injection of supercritical CO2 into deep sedimentary formations is required...

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.

The viability of carbon capture and storage (CCS) to reduce emissions of greenhouse gases depends on the ability to safely sequester large quantities of CO2 over geologic time scales. One concern with CCS is the potential for induced seismicity. We report on ongoing seismic monitoring by the U.S. Geological Survey (USGS) at a CCS demonstration site in Decatur, IL, in an effort to understand the potential hazards posed by injection-induced seismicity associated with geologic CO2 sequestration...

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...
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.
