Here is a link to the University of Texas press release on its important new Barnett shale study. The release includes charts and graphs.
The release starts off: "A new study, believed to be the most thorough assessment yet of the natural gas production potential of the Barnett Shale, foresees slowly declining production through the year 2030 and beyond and total recovery at greater than three times cumulative production to date. This forecast has broad implications for the future of U.S energy production and policy."
