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.

FEATURE: US' Barnett, Haynesville gas output rising even at low price

Even as rig counts have dropped in natural gas shale fields such as the Barnett in North Texas and the Haynesville in East Texas/Northwest Louisiana, production from those plays continues to climb despite persistently low gas prices, analysts say.

Historically, an area's rig count and the rise or fall of its output showed a rough correspondence. But in unconventional plays in the past several years, new drilling mechanics and technology to wrest larger
