The United States is the world's largest producer of natural gas, accounting for about 23% of global production. The majority of U.S. natural gas is produced from shale formations, which are underground rock layers that contain natural gas. The most productive shale formations in the United States are the Marcellus Shale in the Appalachian Basin, the Haynesville Shale in the Gulf Coast region, and the Eagle Ford Shale in Texas.
