Natural resources that are used for heat and power generation, including oil, natural gas, coal, and geothermal energy.
Assessment of undiscovered, technically recoverable oil and gas resources of Armenia, 2014 [ More info] 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.
Coal-bed gas resources of the Rocky Mountain region [ More info] Summary of the technically recoverable coal-bed gas resources of the Rocky Mountain region.
Distribution of high-temperature (>150 °C) geothermal resources in California [ More info] Description and map of geothermal resources in California.
In-place oil shale resources examined by grade in the major basins of the Green River Formation, Colorado, Utah, and Wyoming [ More info] We estimated a total of 4.285 trillion barrels of oil in-place in the oil shale of this area using a geology-based assessment methodology.
In-place oil shale resources in the saline-mineral and saline-leached intervals, Parachute Creek Member of the Green River Formation, Piceance Basin, Colorado [ More info] We estimated 920 and 352 billion barrels of oil are potentially recoverable from oil shale resources using oil-yield cutoffs of 15 and 25 gallons per ton, respectively.
In-place oil shale resources of the Mahogany zone sorted by grade, overburden thickness and stripping ratio, Green River Formation, Piceance Basin, Colorado and Uinta Basin, Utah [ More info] Refinement of previous resource estimate taking into account the characteristics and quality of oil shale as well as the amount of overburden throughout this area.
In-Place Oil Shale Resources Underlying Federal Lands in the Piceance Basin, Western Colorado [ More info] We estimated an in-place oil shale resource of 1.07 trillion barrels under Federal mineral rights, or 70 percent of the total oil shale in place, in this area.
Map of assessed tight-gas resources in the United States [ More info] 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.
National Coal Resources Data System - US Coal Quality Database [ More info] 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.
National Coal Resources Data System - US Coal Resource Database (USGCOAL) [ More info] Searchable database for locating information on coal resources by area, coalfield, coalbed, rank, quadrangle, source, years, or characteristics of thickness, overburden, and reliability.
