Gross production of natural gas in the U.S. has generally been increasing for more than a decade and in recent months has been more than 10% higher compared with the same months in 2017. This growth has been driven by production in the Appalachian Basin in the Northeast, the Permian Basin in western Texas and New Mexico, and the Haynesville Shale in Texas and Louisiana. These three regions collectively accounted for less than 15% of total U.S. natural gas production as recently as in 2007, but now they account for nearly 50% of total production.
Production in these regions has increased in part because of new drilling and completion techniques, including longer well laterals that have increased well productivity. By contrast, the Gulf of Mexico's share of total production, which was 12% in 2007, has fallen to just 3% in recent months, and the share of production in the rest of the U.S. has declined from 60% to 28%.
