U.S. oil production is storming ahead, and the world’s largest economy is on track to become the world’s largest oil producer, too — and it could land the No. 1 crown as early as this year, according to the International Energy Agency.

After ousting Saudi Arabia from the No. 2 spot late last year, U.S. producers should blast past Russia in output “definitely next year,” if not sometime in 2018, said Fatih Birol, executive director of the IEA, according to a Reuters report.

Last year, the U.S. pumped out more than 10 million barrels a day for the first time since the early 1970s, boosted by a rapid ramp-up in shale-oil output. Its production has continued to rise this year: It reached 10.2 million barrels a day in January and is forecast to top 11 million by the end of 2018, according to the U.S. Energy Information Administration.

In comparison, Saudi Arabian oil production currently stands just below 10 million barrels a day, while Russia is pumping about 10.95 million barrels. Both countries have curbed their output as part of a pact between the Organization of the Petroleum Exporting Countries and a group of non-cartel members, part of a joint effort to bring down global crude stockpiles and boost prices.

The OPEC deal, which is set to run through the end of 2018, has largely been credited for the 50% or so rally in oil prices US:CLJ8 UK:LCOK8 logged since summer last year. The U.S. industry isn’t part of the agreement, and American producers have been able to benefit from the price rally without curbing output. That in turn has helped American energy companies take market share from those in countries signed up to the pact.

In its February monthly oil report, the IEA noted that the “colossal” rise in U.S. oil production could scuttle OPEC’s efforts to rebalance the oil market.

“All the indicators that suggest continued fast growth in the U.S. are in perfect alignment; rising prices leading, after a few months, to more drilling, more completions, more production and more hedging,” the agency said in the report.

President Donald Trump is also pushing ahead with his “energy dominance” agenda, aiming for the U.S. to become a net oil exporter over the next 10 years. Deputy energy secretary Dan Brouillette said last week the country is in the “midst of a historic energy revolution” that will gain the U.S. “complete energy security.”
