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.

Profiting from the Shale Boom Regardless of Who's Right


The New York Times recently sparked a wave of controversy after the news organization published a series of stories that questioned the sustainability of the shale gas revolution. These pieces suggested that shale gas producers have overstated the productivity of their wells and that shale gas fields are unprofitable in the current pricing environment.

These articles undoubtedly had their intended effect, mobilizing both critics and supporters of shale gas development and stimulating a vociferous debate. Although arguments that the emperor has no clothes always attract plenty of eyeballs--the primary motivation of many media outfits--readers must evaluate the logic underpinning these claims and distinguish the rational from the sensational.

The New York Times is correct that some shale gas fields are uneconomic in the current pricing environment, which explains why drilling activity has declined in the natural gas-rich Barnett Shale and Haynesville Shale.

But the articles largely ignore the economics of the Eagle Ford Shale and other unconventional fields that produce large amounts of high-value oil, condensate and natural gas liquids (NGL's) such as butane, ethane and propane. In general, exploration and production firms have shifted production from dry-gas fields to liquids-rich plays that offer superior profitability.
