Texas is pumping nearly 35% of all U.S. oil production, according to 2013 numbers from the Energy Information Administration.
Five states and the Gulf of Mexico accounted for more than 80% of all U.S. oil output in 2013 by producing six million barrel per day, the EIA said.
North Dakota was the second-biggest producer with a 12% share.
California and Alaska each accounted for about 7% of America’s production.
Oklahoma had a 4% share.
And about 17% of U.S. oil in 2013 came from offshore production in the Gulf of Mexico.
The EIA said 31 states produced oil.
Total U.S. crude oil production was up 15% last year at 7.4 million barrels per day.
Output by Texas and North Dakota grew by 29% overall in 2013.
Production in North Dakota rose 177% since 2010, and Texas increased by 119% during the past three years.
Colorado, Oklahoma and New Mexico were also among the top ten state producers.
In 2008, the Gulf of Mexico, Alaska and California supplied almost half of U.S. crude, mainly from conventional reservoirs, Fox News said.
“Those three regions provided less than one-third of national output last year,” according to the report.
