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.

Little Gypsy Conversion Officially Dead in La.

NEW ORLEANS -- Louisiana utility regulators officially scuttled a once-touted plan for Entergy Louisiana to convert a generating station to petroleum coke and approved the utility collecting about $200 million from its 669,000 customers to pay for the aborted project.
Entergy Louisiana ( EGYLO.OB - news people ) customers will pay about $1 more per thousand kilowatt hours each month to cover costs from the canceled Little Gypsy power plant in southeastern Louisiana.
But natural gas prices have been on a major slide, partially because of development of the Haynesville Shale in northwestern Louisiana and other shale plays. At the same time, rising construction costs quickly drove the project budget from $1 billion to $1.6 billion. The change of administrations in Washington also brought the uncertainty of carbon legislation from Congress.The plan to convert a generator at the Montz plant from natural gas to petroleum coke was approved by the Public Service Commission in November 2007 when high natural gas prices were hitting billpayers. Petroleum coke is a plentiful byproduct of the refining process.
