U.S. crude oil output rose by 133,000 barrels a day in June to a record 13.58 million barrels a day, according to monthly data released by the Energy Information Administration. The agency revised May’s total down to 13.447 million barrels a day from an earlier 13.488 million, underscoring the scale of the new high. The Gulf of Mexico led the gains with a 67,000-barrel-a-day increase, followed by New Mexico at 40,000, North Dakota at 33,000 and Texas at 11,000. Wyoming added 10,000 barrels a day, while production slipped in Colorado and Alaska by 5,000 and 12,000 barrels a day, respectively. Total U.S. crude oil and petroleum product supply—a proxy for domestic demand—also climbed in June, reaching its strongest level since October 2024, the EIA said.
