"It's been estimated by the Energy Information Agency that we could be the No. 1 oil producer in the world by 2020, surpassing Saudi Arabia. So this is a big deal. It's a game-changing opportunity, and it's of historic proportions," said Jack Gerard, president and CEO of the American Petroleum Institute.
