Haynesville Shale

The Haynesville Shale is a rock formation mainly composed of consolidated clay-sized particles deposited and buried in northwest Louisiana and East Texas more than 170 million years ago during the Upper Jurassic age. It is characterized by ultra-low permeability but has a high porosity compared to other shales.

The Haynesville Shale came into prominence in 2008 as a potentially major shale gas resource. Producing natural gas from the Haynesville Shale involves drilling wells from 10,000 feet and to 13,000 feet deep. The formation is deeper in areas nearer the Gulf of Mexico. The Haynesville Shale has recently been estimated to be the largest natural gas field in the contiguous 48 states with an estimated 250 trillion cubic feet of recoverable gas. Production has boomed since late March 2008, creating a number of new millionaires in the Shreveport, Louisiana region.

'Fracking' Has Definite Downside for Louisiana

Scott Angelle ("Haynesville shale means benefits," June 20): As you should be aware, the U.S. EPA is studying impacts of hydraulic fracturing on drinking water in the United States. The results will be in 2012. I am sure you are aware of the problems with the Carrizo-Wilcox Aquifer around Shreveport which you are not addressing in your Opinion piece in the Daily Advocate

On May 17 at the Louisiana State Senate Environmental Quality Meeting, Sen. Buddy Shaw of Shreveport expressed surprise to Jim Welsh that you are still issuing permits for hydraulic fracturing in the Haynesville shale with the problems with the Carrizo-Wilcox aquifer. You are correct when you state this "goes far beyond just people working. When are you going to address this issue instead of ignoring it and saying "use a different water source when feasible or possible"?
