The United States held onto the top spot as the world’s largest petroleum and natural gas hydrocarbons producer last year.
According to the U.S. Energy Information Administration, the U.S. produced about 30 quadrillion British thermal units (Btu) of petroleum last year and nearly 30 quadrillion Btu of natural gas.
Russia produced just over 20 quadrillion Btu of petroleum and just about 20 quadrillion Btu of natural gas in 2015 while Saudi Arabia produced about 25 quadrillion Btu of petroleum and less than 5 quadrillion Btu of natural gas hydrocarbons.
The U.S. petroleum supply grew by 1 million barrels per day in 2015 while U.S. natural gas production increased by 3.7 billion cubic feet per day.
The gains came despite low crude prices and a 60 percent decline drop in the number of operating oil and natural gas rigs.
U.S. petroleum and natural gas production first surged past Russian production in 2012.
The United States has been the world’s top natural gas producer since 2011 and the world’s top petroleum hydrocarbons producer since 2013.
The growth of U.S. oil and gas production has come thanks to the boom in shale production.
Although Russian petroleum production has continued to grow, the country’s natural gas production declined last year because of poor economic conditions and a mild winter, the EIA said.
Russia’s total combined production of petroleum and natural gas increased by only 0.1 quadrillion Btu in 2015.
Although Saudi Arabia increased its total petroleum and natural gas hydrocarbon production by 3 percent in 2015, the United States still produced more than twice the petroleum and natural gas hydrocarbons as Saudi Arabia produced did last year.
Total production in the United States and Russia were almost evenly split between petroleum and natural gas hydrocarbon production while Saudi Arabia’s production was heavily weighted towards petroleum.
In the United States, crude oil and lease condensate accounted for about 60 percent of the total petroleum hydrocarbon production in 2015.
An additional 20 percent of the U.S. production was attributed to natural gas plant liquids, the EIA said.
Biofuels and refinery processing account for most of the remaining U.S. petroleum and other liquids production volumes.
The EIA said in its latest Short-Term Energy Outlook that it expects U.S. petroleum and other liquid fuels production to decline from 15 million barrels per day in 2015 to about 14.5 million bpd in both 2016 and 2017.
The STEO forecasts Russian liquid fuels production to hold steady at about 11 million barrels per day through 2017.
