Assessments

The Gulf Coast Geologic Energy Assessments and Research (GEAR) project assesses and characterizes undiscovered, technically recoverable domestic petroleum resources. It focuses on the onshore and State waters portion of the Gulf Coast basin. The primary goal of this project is to meet the needs of Congress and other stakeholders for timely and robust assessments of petroleum resources in the Gulf...

To assure adequate uranium to supply electricity from nuclear power, the US Geological Survey is working to better understand the genetic controls, distribution, and quantities of domestic uranium. Because of the heavy reliance on imported uranium, scientists also lead international groups of uranium resource experts to monitor world uranium supply. This research benefits the mining industry...

The U.S. Geological Survey (USGS) has updated the previous 2008 assessment of undiscovered, technically recoverable gas hydrate resources beneath the North Slope of Alaska. This new 2018 assessment again indicates the existence of technically recoverable gas hydrate resources―that is, resources that can be discovered, developed, and produced using current technology. Using a geology-based...

The USGS World Energy Project conducts geologic studies that provide an understanding of the quantity, quality, and geologic distribution of world oil and gas resources. Our geologic studies are conducted in an impartial manner and are performed in collaboration and partnership with energy experts within and outside government. Through synthesis and improved understanding of global oil and gas...

USGS Energy Resources Program provides periodic assessments of the oil and natural gas endowment of the United States and the World. This website provides access to new, prioritized, assessment results and supporting data for the United States, as part of the Energy Policy and Conservation Act (EPCA).

Work in this task of the Oil and Gas Waters Project focuses on quantifying the water used during hydrocarbon development and the water produced along with oil and gas. Hydraulic fracturing is an integral part of oil and gas development in many areas, and water use for this purpose has increased considerably in the last decade. Water produced from petroleum reservoirs includes hydraulic fracturing...

The USGS has conducted several assessments of undiscovered oil and gas in formations in the Blue Ridge Thrust Belt (5068), Piedmont Province (5069), Atlantic Coastal Plain Province (5070), and the New England Province (5072). These basins are generally east of the Appalachian Basin Province (5067).

The primary objective of this project is to provide information on the volume, quality, impacts, and possible uses of water produced during generation and development of energy resources (particularly hydrocarbons) as well as related fluids injected into reservoirs for energy development and associated waste disposal. The purpose of this work is to address scientific and societal questions...

The USGS Energy Resources Program has studied oil shale resources of the United States, with a significant effort on the Eocene Green River Formation of Colorado, Utah, and Wyoming. This formation contains the largest oil shale deposits in the world. Oil shale, despite the name, does not actually contain oil, but is a precursor of oil that is converted to crude oil when heated.

The U.S. Geological Survey completed the following assessments of undiscovered oil and gas resources of the Cincinnati Arch Province (5066) :

The U.S. Geological Survey completed the following assessments of undiscovered oil and gas resources of the Arkoma Basin Province 5062.

The U.S. Geological Survey completed the following assessments of undiscovered continuous oil and gas resources of the Southern Oklahoma Province (5061).
