Areas where masses of naturally occurring mineral material are found, e.g. metal ores or nonmetallic minerals. [Adapted from Glossary of Geology, 4th ed.]
We estimated between 3.2 and 5.6 billion barrels of additional oil may be recovered with existing technology in this area using a probabilistic geology-based assessment methodology.
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.
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.
We estimate mean volumes of 896 million barrels of oil and about 53 trillion cubic feet of nonassociated natural gas in conventional, undiscovered accumulations within this area, a reduction of our 2002 estimate due to new geologic information.
We estimated in-place resources of 1.07 trillion short tons of coal in this area using a geology-based assessment methodology. Of that total, recoverable coal was 162 billion tons, 25 billion economically recoverable.
Estimates of additional energy resources present within known oil and gas fields using statistical analysis that includes geology and engineering practices in addition to growth trends in production data.
The mean total volume of potential additional oil resources that might be added using improved oil-recovery technologies was estimated to be about 2.7 billion barrels of oil.
The mean total volume of potential oil reserves that might be added in the nine fields using improved oil-recovery technologies was estimated to be about 6.5 billion barrels of oil.
We estimated the volume of oil, natural gas, and natural gas liquids in three closely related geologic units in this area using a geology based assessment methodology.
We estimated a mean of 4.06 trillion cubic feet of undiscovered, technically recoverable natural gas in these coal beds of the onshore lands and State waters of the Gulf Coast.
