The United States is on pace to leapfrog both Saudi Arabia and Russia and reclaim the title of the world’s biggest oil producer for the first time since the 1970s.

The latest forecast from the U.S. Energy Information Administration predicts that U.S. output will grow next year to 11.8 million barrels a day.

“If the forecast holds, that would make the U.S. the world’s leading producer of crude,” says Linda Capuano, who heads the agency, a part of the Energy Department.

Saudi Arabia and Russia could upend that forecast by boosting their own production. In the face of rising global oil prices, members of the OPEC cartel and a few non-members including Russia agreed last month to ease production caps that had contributed to the run-up in prices.

President Trump has urged the Saudis to pump more oil to contain rising prices. He tweeted on June 30 that King Salman agreed to boost production “maybe up to 2,000,000 barrels.” The White House later clarified that the king said his country has a reserve of 2 million barrels a day that could be tapped “if and when necessary.”

The United States led the world in oil production for much of the 20th century, but the Soviet Union surpassed America in 1974, and Saudi Arabia did the same in 1976, according to Energy Department figures.
