There’s no getting around the fact that the Marcellus/Utica region, collectively called Appalachia, is THE 800-pound gorilla when it comes to natural gas production. We produce more natgas than any other region of the country–more than twice as much as the next highest producer, the oily Permian Basin. Yet the Haynesville Shale, a gas-focused play located in Louisiana, also produces a lot of natgas (about 36% of what the M-U produces). According to recent research by the U.S. Energy Information Administration (EIA), new wells in the Haynesville are more productive (producing more gas on average) than new wells drilled in the M-U. Huh.
