We estimated mean undiscovered volumes of 7.4 billion barrels of oil, 6.7 trillion cubic feet of associated/dissolved natural gas, and 0.53 billion barrels of natural gas liquids in this area using a geology-based assessment methodology.
We estimated mean volumes of 53 trillion cubic feet of shale gas, 172 million barrels of shale oil, and 176 million barrels of natural gas liquids in this area using a geology based assessment methodology.
We estimated mean volumes of 1 million barrels of undiscovered, technically recoverable conventional oil and 6 billion cubic feet of undiscovered, technically recoverable conventional natural gas in this area using a geology-based assessment methodology.
Estimates of uranium resources affected by land withdrawal, effects of previous breccia-pipe mining, water-chemistry data for streams and springs, and potential biological pathways of exposure to uranium and associated contaminants.
90 billion barrels of oil, 1,669 trillion cubic feet of natural gas, and 44 billion barrels of natural gas liquids may remain to be found in the Arctic, of which approximately 84 percent is expected to occur in offshore areas.
Landscape changes in ground disturbance, land use and land cover, condition of forests, temperature, albedo, and others may have effects on the ecosystem that need to be understood as natural resources are discovered and exploited.
Shows where there are potential commercial sources of natural gas trapped in formations with very low permeability to gas (not necessarily shale units). Hydraulic fracturing might be needed in order to exploit these resources.
Searchable database, the COALQUAL database, presented here and in the USGS Open-file Report 97-134, is a subset of samples contained in the NCRDS (National Coal Resources Data System) database, and contains coal quality data on each sample.
Using a performance-based geological assessment methodology, we estimated mean volumes of 1,345 billion cubic feet of potentially technically recoverable gas and 168 million barrels of technically recoverable oil and natural gas liquids here.
Estimates of known and undiscovered copper resources total nearly 60 million metric tons of copper. Iron resources in known deposits total 2200 million metric tons of ore. Twenty mineralized areas meriting further study were identified.
Mines, mineral processing facilities, and petroleum facilities as well as information on location, operational status, and ownership in Cuba, as well as current status of known mineral industry projects and trends in the industry there.
Shows where important mineral resources are located in Afghanistan, the type of deposits there, the commodities that are present, and describes the data available to support further exploration and exploitation of these resources.
Describes organizational process and field study used to estimate production capacity (mostly by artisanal miners) in the parts of the country likely to contain diamonds. We estimate a production capacity of 600,000 carats per year.
Information on the mineral industry in these countries, the operating status of mining projects through 2014, and coordinated actions by mining companies to support governments and international relief organizations to contain the Ebola outbreak.
Presentation describing uses of rare earth elements, why they are important, where they occur and are produced, and aspects of the economics of production and consumption with emphasis on sites that might be developed for production.
Contaminants from mines move more easily from ore materials and mine waste piles to surrounding estuaries and living organisms when water moves through the mine site. Geochemical results shown here will help people mitigate the negative effects.
