After reaching a record high of 79 billion cubic feet per day (Bcf/d) in 2015, U.S. marketed natural gas production fell to 77 Bcf/d in 2016, the first annual decline since 2005. Texas, the state with the most natural gas production, fell by 2.5 Bcf/d, while Ohio and Pennsylvania each increased by about 1.2 Bcf/d. Pennsylvania and Ohio had the two largest annual natural gas production increases from 2015 to 2016, reflecting higher production from the Utica and Marcellus shale plays.
Pennsylvania surpassed Louisiana in 2013 to become the second-highest natural gas producing state, behind Texas. Although both states had higher production in 2016, Ohio surpassed West Virginia last year to become the seventh-highest natural gas-producing state.
