Article Summary. According to the International Energy Agency (IEA), increased
oil production resulting from U.S. shale oil has invigorated the North American oil
industry and has created a global supply shock. The shale oil and gas industry has
generated tens of billions of dollars in revenues and hundreds of thousands of new
jobs, and could result in the United States changing from being the world’s largest

by 2017, with supply growing by 3.9 million barrels per day from 2012-2018.
