Excerpt: The Barnett Shale is a geological formation located in the Bend Arch-Fort Worth Basin. It consists of sedimentary rocks of Mississippian age (354-323 million years ago) in Texas. The formation underlies the city of Fort Worth and underlies 5,000 square miles (13,000 km) and at least 17 counties. Some experts have suggested the Barnett Shale may have the largest producible reserves of any onshore natural gas field in the United States. The field is proven to have 2.5 trillion cubic feet (7.1 m) of natural gas, and is widely estimated to contain as much as 30 trillion cubic feet (8.5 m) of natural gas resources. Oil also has been found in lesser quantities, but sufficient (with recent high o...
