Crude oil production in the United States is expected to amount to 28.26 quadrillion British thermal units in 2025. Despite many governments intensifying searches for renewable alternatives to fossil fuel energy production, production is forecast to increase until at least 2027. One standard barrel of crude oil contains about 5.8 million British thermal units. 

U.S. oil production gains in the past decade

Thanks to hydraulic fracturing, the United States has been able to position itself as the largest oil producer worldwide. Fracking allows them to extract oil from permeable rock formations, such as shale or tight sandstone. This type of oil is referred to as tight oil or unconventional oil. In the U.S., most shale formations are located in Texas and North Dakota. Since the rapid expansion of fracking, these states have become two of the country’s largest producers of crude oil. The largest oil producing region is the Permian basin in Texas and New Mexico.

Most productive oil basins

Also, as of May 2025, the Permian basin ranked as the third-largest producer basin of new-well oil, generating slightly over 1,500 barrels per day per rig. The Bakken basin was the largest new-well oil producer that month, with nearly 1,800 barrels per day per rig. New-well oil refers to initial crude oil output from recently drilled and completed wells, a key metric in the oil and gas industry used to assess early well productivity.
