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.

Haynesville fire dangers remains high


Bentek said in a market alert the fires could threaten the Haynesville Shale, one of the largest natural gas shale plays in the United States, producing just over 5 billion cubic feet per day, Reuters reported.
A sample of production receipts from East Texas and Haynesville had not yet shown a distinct decline in production that could be attributable to the fires, but some of the fires have erupted around the perimeter of Haynesville shale counties, raising concerns about safety and disruptions, the report noted.
The fires had, however, shown an impact on demand.
"Over the last three days, evacuations and fire-related damage in Texas have led to nearly 1 Bcf total demand loss," Reuters quoted the report as saying.
Bentek expects demand recovery to be gradual.
"Texas has experienced the largest fire event of the three states, with a total of 26 large fires burning and nearly 114,000 acres burned as of September 8. Forecasts for fire danger remain high in the majority of the East Texas region," the report said.
Bentek noted Louisiana's state department of natural resources last week issued an advisory to oil and gas operators in the state to monitor conditions closely and take necessary steps, including shutting in wells, production facilities and pipelines as needed.
The fires had burned acres in one of the core production counties, Harrison, and four of the "non-core" counties, Gregg, Marion, Nacogdoches and Rusk.
"If fires were to erupt in more developed areas of the shale, operations would undoubtedly have to be shut-in, restricting production. Even without a fire, downed power lines or disruptions in power transmission could also impact operations of pump jacks and compressor stations.
