Natural resource assessment
Estimation of the actual or potential value of natural materials and processes.
Eastern Mineral Resources [ More info] Home page for Eastern Mineral Resources Team conducting research on the occurrence, quality, quantity, and availability of mineral resources. Links to products, descriptions of research projects, and staff.
Estimate of undiscovered copper resources of the world, 2013 [ More info] We estimated a mean of 3,500 million metric tons (Mt) of undiscovered copper among 225 tracts around the world using a geology-based assessment methodology.
Great Lakes assessment of water availability and use [ More info] Information about basin storage, historical changes, and consumptive water use for manages and planners to use to develop policies for efficient and sustainable water use.
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.
Marine aggregate resources and processes [ More info] Regional studies mapping the seafloor sedimentary character and assessing marine sand and gravel resources around the United States, to inform beach nourishment and coastal restoration, benthic habitat and sediment transport studies
Nahcolite Resources in the Green River Formation, Piceance Basin, Northwestern Colorado [ More info] Resource assessment of nahcolite, a mineral with a variety of industrial uses, which occurs with oil shale and is affected by the processes used to recover hydrocarbons from the rock.
