The growth in production is due to the relatively high prices for the oil. We wouldn’t be producing from the expensive shale fields if the prices were falling deep.
We have China, India and Brazil to thank. Were it not for those booming economies, OPEC would drive down crude prices and drive U.S. domestic unconventional exploration and production out of business. As it stands, OPEC doesn't need to worry about declining U.S. imports.
I can understand that high prices provide an incentive for shale production, but shouldn't the increased production from shale eventually reduce prices at the pump?
