The Bossier formation
Geology, footprint, and mineral-owner context for the Bossier, drawn from public USGS and state survey sources. Resource figures describe the play as a whole and are not a per-acre value. Every figure on this page is an estimate subject to verification of your specific interest.

What is the Bossier?
The Bossier is the Jurassic-age gas shale stacked directly above the Haynesville in northwest Louisiana and East Texas, developed as a second target across the same parishes and counties. The USGS assessed the Haynesville and Bossier formations together at a mean of about 47.9 trillion cubic feet of undiscovered, technically recoverable gas, a play-wide figure rather than a per-acre yield.
The Bossier shale sits just above the Haynesville and shares its deep, over-pressured, gas-rich character. In much of the play the two are developed together, so a tract producing Haynesville gas may also have Bossier potential, adding a second stacked target on the same acreage. Like the Haynesville, the Bossier is concentrated in the northwest Louisiana parishes of DeSoto, Caddo, Bossier, and Red River and the deep East Texas counties of Harrison and Panola, and it is dry-gas, so royalties track natural-gas prices. For a mineral owner, a Bossier interest is valued on the income the wells pay, on the standard income multiple, not on the play-wide resource estimate.
Bossier geology
- Age and lithology
- Upper Jurassic organic-rich shale lying directly above the Haynesville, deep and over-pressured. Source: USGS Gulf Coast assessment.
- Stacked with Haynesville
- Often developed as a second target above the Haynesville, so one tract can carry both intervals.
- Where it produces
- The same fairway as the Haynesville: northwest Louisiana parishes and deep East Texas counties.
How much oil and gas the Bossier holds
The 2025 USGS assessment of the Haynesville and Bossier formations of the Gulf Coast estimated a combined mean of about 47.9 trillion cubic feet of undiscovered, technically recoverable natural gas. This is an undiscovered play-wide estimate, not proven reserves and not a measure of any individual property.

Counties in the Bossier play
These are the counties and parishes we cover where the Bossier produces. Each links to local value context and the operators active there.
What the Bossier means for your minerals
A resource estimate for a play is not the value of your acreage. Your mineral and royalty interest is valued on the income your wells actually pay, roughly 36 to 72 times your average monthly royalty check, the same as 3 to 6 times your annual royalty. Where you land in that band depends on your wells decline, the operator, your royalty rate, and any undeveloped drilling upside.

The Bossier is part of the Haynesville Shale. For the basin-wide value bands and the counties we buy in, see the Haynesville Shale page.
Bossier questions
- What is the Bossier formation?
- The Bossier is a Jurassic-age gas shale stacked directly above the Haynesville in northwest Louisiana and East Texas. It is developed as a second target across the same parishes and counties as the Haynesville.
- How is the Bossier different from the Haynesville?
- The Bossier sits just above the Haynesville and is a separate but similar deep, over-pressured gas shale. Where both are present, they can be developed from the same acreage, adding a stacked target.
- How are Bossier minerals valued?
- A Bossier interest is valued on the gas income it pays, roughly 36 to 72 times your average monthly royalty check, and like the Haynesville it tracks natural-gas prices. USGS resource figures describe the whole play, not your property. This is an estimate, subject to verification, not an offer.
