Barnett Shale may be the largest onshore natural gas field in the United States. While proven to have 2.5 trillion cubic feet of natural gas, it could contain as much as 30 trillion cubic feet! Not until the technological advancement of horizontal drilling though was Barnett Shale able to become a major producer of natural gas. Horizontal drilling allows companies to drill horizontally – this is key because DFW basically sits on top of Barnett Shale. Now drillers can retrieve natural gas that lies beneath neighborhoods. Cha ching!
