Not in the least. The Bakken formation is estimated to have anywhere from 4 billion (current technology & cost) to max 24 billion barrels (future technology & future price of oil) of recoverable oil. The US alone consumes about 7 billion barrels a year annually. At the low end, Bakken will maybe last us 6 or 7 months. At the very high end Bakken would only provide about a 3 and half year supply for the US.
So, on a global scale, Bakken won't make a dent.
