Areas where masses of naturally occurring mineral material are found, e.g. metal ores or nonmetallic minerals. [Adapted from Glossary of Geology, 4th ed.]
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 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.
Using a geology-based assessment methodology, we estimated the mean undiscovered conventional petroleum resources to be 31,400 million barrels of oil equivalent, present in oil, gas, and natural gas liquids.
We estimated mean undiscovered resource volumes of 21.55 million barrels of oil, 44.76 billion cubic feet of non-associated natural gas, and 0.91 million barrels of natural gas liquids in the western Afghanistan Tirpul Assessment Unit.
We estimated mean undiscovered, conventional, technically recoverable petroleum resources in the Barents Sea Shelf to be more than 76 billion barrels of oil equivalent using a geology-based assessment methodology.
We estimated the mean undiscovered, conventional petroleum resources at 28 billion barrels of oil equivalent, including approximately 8 billion barrels of crude oil, 106 trillion cubic feet of natural gas, and 3 billion barrels of natural gas liquids.
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.
