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.
PDF Assessment of Undiscovered Petroleum Resources of the Barents Sea Shelf [More info]
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.
PDF Assessment of Undiscovered Petroleum Resources of the North and East Margins of the Siberian Craton, Russian Federation [More info]
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.
PDF Assessment of coal geology, resources, and reserve base in the Powder River Basin, Wyoming and Montana [More info]
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.
PDF Assessment of in-place oil shale resources of the Green River Formation, Greater Green River Basin in Wyoming, Colorado, and Utah [More info]
Using the Fischer assay measure of oil yield, we estimated a total of 1.44 trillion barrels of oil in three assessed units. There is currently no economic method to recover oil from this geologic unit.
