Scientific study of the formation, location, and use of marketable geologic materials including fuels, metals, minerals, and water.
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.
Lead-Soft and easy to cast [ More info] Explains how we use lead, where it comes from, and how we might ensure that we have adequate supplies of this mineral commodity in the future.
Limestone - A crucial and versatile industrial mineral commodity [ More info] Uses and availability of limestone and related commodities such as lime and portland cement. Hazards of limestone terranes due to erosion and sinkhole formation.
Lithium: for harnessing renewable energy [ More info] Explains how this element is used, where we get it, and prospects for future supply and demand.
Manganese: it turns iron into steel (and does so much more) [ More info] Explains how we use this metal, where we get it, and describes the current trends in supply and demand.
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.
Microbial production of natural gas from coal and organic-rich shale [ More info] Explains how natural gas can be formed by microorganisms from geological materials, and how we plan to assess the potential value of this process for improving energy resources.
