||Bend Arch-Fort Worth Basin, Texas
||The Barnett Shale is a hydrocarbon-producing geological formation of great economic significance to Texas. It consists of sedimentary rocks and the productive part of the formation is estimated to stretch from the city of Dallas west and south, covering 5,000 square miles (13,000 km˛) and at least 18 counties. It is estimated that the Barnett Shale is more then 6,000 feet deep and very thick. Some experts say that the Barnett Shale is the largest onshore natural gas field in the United States. The field name for the productive portion of the Barnett Shale formation has been designated as the Newark, East Field by the Texas Railroad Commission.
||The Barnett Shale has a chance one day to produce 3-4 billion cubic feet of natural gas per day. Future development of the Barnett Shale could be tricky as the Dallas - Fort Worth areas become heavily populated.
||The Barnett Shale is a rock formation deep below the Texas surface which was discovered by wildcatters in the 1950's. In 1980, technological advances enabled companies to extract natural gas from the Barnett Shale. The Barnett Shale Field has been referred to as the biggest natural gas field in the United States, having been proved to hold up to 5 trillion feet of Natural Gas.
