In 2022, Pennsylvania accounted for 19% of U.S. marketed natural gas production, with more natural gas produced than in any other state except Texas. Marketed natural gas production in Pennsylvania fell slightly by 2% to average 20.5 billion cubic feet per day (Bcf/d) in 2022 after reaching an annual high of 20.9 Bcf/d in 2021, according to our Natural Gas Monthly. Natural gas production in Pennsylvania comes largely from the Marcellus shale gas play. In 2022, productivity declines and a plateauing of natural gas takeaway capacity resulted in the small decrease in production of 0.4 Bcf/d in Pennsylvania.
