Natural gas production in the Marcellus Region exceeded 15 billion cubic feet per day (Bcf/d) through July, the first time ever recorded, according to EIA's latest Drilling Productivity Report. The Marcellus Region, mostly located in West Virginia and Pennsylvania, is the largest producing shale gas basin in the United States, accounting for almost 40% of U.S. shale gas production. Marcellus Region production has increased dramatically over the past four years, increasing from 2 Bcf/d in 2010 to its current level.
