from U.S. Energy Information Administration
U.S. field production of crude oil increased in 2015 for the seventh consecutive year, reaching 9.42 million barrels per day (b/d). This was the highest crude oil production level since 1972, based on final production numbers in EIA's Petroleum Supply Annual. In 2015, production gains were highest in Texas, the Gulf of Mexico, and North Dakota, as these three regions accounted for 77 percent of the U.S. total increase.
