The Star Telegram has an article on falling Barnett Shale production: "Natural gas production in the Barnett Shale fell below 5 billion cubic feet a day in June, the lowest since December 2009, a new report said. *** Powell Shale Digest, an online industry newsletter, said its analysis of Texas Railroad Commission monthly reports shows that the big North Texas gas field produced an average 4.84 billion cubic feet a day in June. That's down 16.5 percent from a year earlier and down 20.8 percent from two years earlier." Notably: "It has been surpassed by the Marcellus Shale in Appalachia as the most productive U.S. natural gas field."
Interesting.
