Haynesville Shale
The East Texas and northern Louisiana counties making up the Haynesville Shale formation came to the public's attention in 2008, when exploration companies began flocking to the region in search of its unconventional gas resources. However, the area has been tapped for conventional oil and natural gas deposits since the start of the 20th century. Using the tabs below, learn more about the history of oil and gas extraction in the Haynesville Shale and drilling's effects on economic activity in the area.
Highlights |
---|
The Haynesville Shale formation covers 23 counties on the border of Texas and Louisiana.[1] The region is rich in natural gas. DeSoto parish in Louisiana leads the region in natural gas production. With over 3.3 billion cubic feet of natural gas production per day in fourth quarter 2021, De Soto parish accounted for 23.4 percent of the Haynesville's output.[2] |


Notes
- The Energy Information Administration also includes two Arkansas counties in the Haynesville Shale: Columbia, AR and Lafayette, AR. These counties are outside of the Eleventh District. Thus, they are excluded from this analysis.

The Haynesville Shale underlies a 9,000-square-mile area straddling East Texas and northern Louisiana.[1] The area has produced natural gas and oil through conventional wells for decades. These wells draw oil and gas from part of the Texas-Louisiana-Mississippi Salt Basin. Over the last decade, drilling activity has focused on both the salt basin and the unconventional resources of the Haynesville Shale.
Before the Shale Boom
In the conventional deposits of the Texas-Louisiana-Mississippi Salt Basin, oil and gas pool under ceilings of impermeable rock that were pushed up by a rising column of salt.[2] Drillers have used vertical wells to tap these reservoirs since the beginning of the 20th century.[3] In the decades preceding the shale boom, local drillers endured several boom-and-bust cycles (Chart 1). Most recently, drilling activity increased from 2002 until the start of 2008, spurred by higher natural gas prices. This led to production growth in many counties in the area.
The shale boom opens a new chapter in the area's long history of fossil fuel extraction. In contrast to the conventional deposits associated with the salt basin,[4] the unconventional natural gas deposits in the Haynesville Shale remain trapped in a 250-foot-thick layer of rock that lies 2 miles or more below the earth's surface.[5]
Chesapeake Energy began drilling exploratory wells in the Haynesville Shale in 2006. Combining recent advances in hydraulic fracturing and horizontal drilling, the company successfully extracted natural gas from the dense rock. Chesapeake released its findings in March 2008. Shortly thereafter, a gold rush atmosphere hit the area, with significant increases in drilling. At the peak in 2010, drillers spudded 875 wells in the Louisiana portion of the Haynesville Shale (Chart 2). Natural gas production skyrocketed in a short period of time, with the increases concentrated in four counties in Louisiana and two in Texas.
The Shale Bust?
In recent years, area activity has fallen significantly from its 2010 peak. In one sense, the Haynesville has been a victim of its own success (and that of other shale plays). Production of natural gas in the U.S. increased so much that natural gas prices plummeted, remaining depressed for several years. This discouraged drilling for new natural gas wells, not only in the Haynesville but also elsewhere.
The Haynesville Shale also has two characteristics making it less attractive than other shale plays. First, the shale is unusually deep, where drilling becomes relatively expensive. Second, the Haynesville produces primarily natural gas while other plays, such as the Eagle Ford in South Texas, also contain crude oil and natural gas liquids (NGLs).[6] Both crude oil and NGLs currently sell for more than natural gas (Chart 3).
In spite of recent declines in activity, natural gas production remains significantly elevated compared with the pre-boom period, and the area still has plenty of potential for future growth. Geologists estimate that the play still contains roughly 75 trillion cubic feet of technically recoverable natural gas.[7] In addition, drillers in the area enjoy a dense network of pipelines and close proximity to refineries and petrochemical plants on the Gulf Coast. This suggests the area could see renewed activity if natural gas prices sufficiently rise in the future.

Production Before the Shale Boom
Highlights (Pre-Boom) |
---|
In the years preceding the shale boom, the Haynesville Shale experienced notable increases in natural gas production. As a result of these gains, the share of U.S. natural gas produced in the Haynesville region ticked up 2 percent.[1] Production increased faster in Texas than Louisiana in these years, with Nacogdoches and Harrison counties recording the most significant increases. From first quarter 2002 to first quarter 2008, natural gas production increased by over 900 million cubic feet per day in the Texas Haynesville counties and by 600 million cubic feet per day in the Louisiana Haynesville parishes.[1] |





Production after the Shale Boom
Highlights (Post-Boom) |
---|
With the start of the shale boom in 2008, natural gas production in the Haynesville skyrocketed. Production across the Haynesville has declined in recent years, but the formation still produces 12.5 percent of all U.S. natural gas.[1] Louisiana has recorded the strongest natural gas production gains since the shale boom. Even with the recent declines in production, the Louisiana Haynesville parishes produced around 8.00 billion cubic feet more natural gas in fourth quarter 2021 than in first quarter 2008. DeSoto parish alone accounted for 37 percent of this increase.[1] |

Data showing the number of rigs operating in each U.S. county became readily available in 2011. Since the start of that year, most drilling activity in northern Louisiana and Texas Railroad Commission District 6 has focused on the Haynesville shale; however, the number of active rigs has declined sharply.[1] Horizontal drilling dominates activity in the Haynesville shale, typically accounting for around 90 percent of all rigs.[2] |

Notes
- The Louisiana Department of Natural Resources illustrates the dividing line between north and south Louisiana. Texas Railroad Commission District 6 covers 23 counties in northeast Texas, 13 of which are part of the Haynesville shale formation.
- Vertical rigs drill straight down through the earth. Directional rigs can drill horizontally, but they can take several hundred feet to change from vertical to horizontal. In contrast, horizontal rigs can drill straight down and make a 90-degree turn in just a few feet.
Labor Markets
Highlights |

Since 2001, mining employment in the Texas Haynesville counties has grown more than 40 percent; the rest of Texas has also experienced robust employment growth in mining employment.[1] In Louisiana, mining employment in the Haynesville parishes grew rapidly until 2011, but it declined steeply the following two years. Mining employment in the rest of Louisiana remained flat from 2001 to 2014 and has since declined.[2] In both the Texas and Louisiana Haynesville, employment in industries other than mining grew at a much slower pace. As a result of these differences in growth rates, the share of employment in mining increased markedly. The largest increases occurred from 2002 to 2008; mining's share more than doubled in some counties. Since the Haynesville boom began in 2008, mining's employment share has continued growing in some areas. In both mining and industries outside of mining, average weekly wages in the Haynesville are lower than those in the rest of Texas and Louisiana. |

Taxable sales in the Texas Haynesville counties grew 17 percent from mid-2005 to mid-2009, compared with 14 percent for the rest of the state.[1] However, since mid-2010, taxable sales growth in these counties trailed the rest of Texas. From mid-2005 through mid-2010, taxable sales in the Louisiana Haynesville parishes performed at least as well as in the rest of the state. After drilling activity began to weaken, however, the Louisiana Haynesville parishes' taxable sales declined, while they rose in the rest of the state. |
