Shale was largely behind the glut of American oil that flooded the market more than four years ago, leading oil prices to fall to $30 a barrel from more than a $100 a barrel in late 2014.
U.S. shale production in 2018 grew faster than it did during the boom years of 2011 to 2014, the IEA said last year.
The U.S. last year surpassed Russia and Saudi Arabia to become the world’s largest producer of crude oil, with output currently hovering around 12 million barrels a day.
U.S. crude production is expected to rise to 13.7 million barrels a day by the end of its five-year forecast period, the IEA said Monday.
“Annual gains will boost the U.S. to levels never seen in any country, in excess of maximum capacity in both Russia and Saudi Arabia,” the report noted.
