The United States will surpass Saudi Arabia later this year in exports of oil, natural gas liquids and petroleum products, like gasoline, according to energy research firm Rystad Energy.

That milestone, driven by the transformative shale boom, would make the United States the world’s leading exporter of oil and liquids. That has never happened since Saudi Arabia began selling oil overseas in the 1950s, Rystad said in a report Thursday.

“It’s nothing short of remarkable,” said Ryan Fitzmaurice, energy strategist at Rabobank. “Ten years ago, no one thought it could happen.”
