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.
We estimated means of 19 billion barrels of oil and 83 trillion cubic feet of undiscovered natural gas resources in 10 geologic provinces of this area using a geology-based assessment methodology.
