In 2013, five states and the Gulf of Mexico supplied more than 80% of the crude oil produced in the US, the equivalent of 6 million bpd. Texas alone provided 35%, according to preliminary data released by the EIA in its March Petroleum Supply Monthly. The second largest state producer was North Dakota with 12% of US crude oil production, followed by California and Alaska at close to 7% each and Oklahoma at 4%. The federal offshore Gulf of Mexico produced 17%.
Production growth rates
Total US crude oil production increased by 15% last year to 7.4 million bpd. Texas and North Dakota lead the growth with their outputs increasing by 30% and 29% respectively from 2012 levels. Production gains in both states come largely from shales, especially Eagle Ford, Texas and Bakken, North Dakota. Since 2010, North Dakota’s crude oil output has grown 177% and Texas’ output 121%.
Three other US states among the top 10 producers for last year also experienced production growth rates above 20%. Colorado had a 93% growth rate between 2010 and 2013, Oklahoma 62% and new Mexico 51%.
Crude oil is produced in 31 states and two offshore federal regions. Of those 33 producing areas, 10 supply more than 90% of US output. While 9 of those top 10 were also among the top 10 producers five years ago, their relative contributions have changed.
North Dakota has risen from 7th largest oil producer to 2nd. The Gulf of Mexico, Alaska and California which together in 2008 supplied nearly half of US crude production mainly from conventional oil reservoirs, provided less than one third of national output in 2013. Output in those areas has declined at the same time that overall national production has expanded.
