World Oil and Gas Resource Assessments
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...
United States Assessments of Undiscovered Oil and Gas Resources
USGS Energy Resources Program provides periodic assessments of the oil and natural gas endowment of the United States and the World (click here for information about World Oil and Gas Assessments). This website provides access to new, prioritized, assessment results and supporting data for the United States, as part...
Quantities of water associated with oil and gas development
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...
Eastern Basins Oil and Gas Assessments
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...
Oil and Gas Waters Project
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...
