Attached is a set of graphs that depict historical natural gas production for the State, Shreveport District and Haynesville Shale Area (8 Parishes). The largest increases since mid-2008 have occurred in DeSoto, Red River, Caddo & Bossier Parishes. You can see how the production growth rate for the Shreveport District accelerated with the switch to Haynesville Shale drilling.
Also of note is the nice surge in production from LCV production coming online ca. 2003-05 which primarily affect the Caddo / Bossier / Webster datasets. But the 'HA surge' in Red River and Desoto is (at the very least) impressive. Wow.
Poor Natchitoches - one well completion made the impact spike anomaly at 2008-09. I have the feeling that those numbers are about to change in the next few months, as companies start plumbing for that elusive south boundary and popping the Mid Bossier.
