U.S. oil production surged to an all-time high in November, topping the previous record set nearly half a century ago, government data showed on Wednesday.
The nation's drillers pumped 10.057 million barrels a day in November, the U.S. Energy Information Administration said in a monthly report. That edges out the previous record of 10.044 million barrels a day set in November 1970.
The record-setting output comes after a revision to last month's report showing November's output leaped to 10.038 million barrels a day.
While the new all-time high production shows American drillers pulled ahead of Saudi Arabia to briefly become the world's second biggest producer, the United States may have slipped back into third place in December. The first monthly reading for December shows U.S. output slid back to 9.949 million barrels.
Saudi Arabia pumped just under 10 million barrels a day in December, according to figures from the kingdom and independent sources. The Saudis are limiting their output as part of a deal among two dozen producer nations that aims to reduce global stockpiles following a prolonged oil price slump.
Saudi Arabia was producing as much as 10.7 million barrels a day before it began turning off the taps, but U.S. drillers are on pace to produce roughly that much this year. EIA forecasts American production will average 10.6 million barrels a day in 2018.
EIA projects U.S. output will average 11.2 million barrels a day next year, positioning the nation to overthrow Russia as the world's top producer.
The slide in December was largely due to a drop in production in the Gulf of Mexico.
Surging U.S. production is being driven by booming output from America's shale fields, where drillers use advanced drilling methods to squeeze oil and gas from shale rock formations.
Texas, the biggest shale oil producing state, has seen its production jump by 780,000 barrels a day over the last year. Production also rebounded last year in other states with large shale basins, including Colorado, New Mexico, North Dakota and Oklahoma.
