The Bakken Formation in the western U.S. is reported to hold billions of barrels of oil. Assuming that 8 billion barrels of this oil is fully recoverable, is this a significant source of oil for the U.S.? (For this question, you can assume that the U.S. consumes 20 million barrels of oil per day.)

B. Yes, the 8 billion barrels is enough to significantly offset U.S. reliance on foreign oil
C. No, the 8 billion barrels is only enough to supply the U.S. for just over one year at present total consumption rates
D. None of the above
