Bakken Formation has 3 billion to 4.3 billion barrels of recoverable oil, USGS says
BISMARCK--The Bakken Formation in North Dakota and Montana have 3 billion to 4.3 billion barrels of recoverable oil, a federal report released today says.
"This is the largest oil accumulation in the lower 48," said U.S. Geological Survey scientist Brenda Pierce.
The number is 25 times more than the amount of recoverable oil that the U.S. Geological Survey's 1995 estimate reported, but far less than the 400 to 500 billion barrels of oil estimated by a now-deceased USGS scientist.
