# Western Haynesville Mineral Rights: Brazos, Grimes, Madison, Robertson & Leon Counties (2026)

**TL;DR:** The Western Haynesville is a Comstock Resources-led extension of the Haynesville/Bossier shale gas play into East-Central Texas counties (Robertson, Madison, Brazos, Grimes, Leon), targeting deep gas intervals often exceeding 15,000 feet TVD. While still in earlier-stage development compared to the Louisiana–East Texas core, multiple horizontal completions have validated commercial potential, with many sections offering stacked-pay opportunities across the Austin Chalk, Buda, Eagle Ford-equivalents, Bossier, Haynesville, and Smackover formations.

## Key Takeaways

- **Western Haynesville defined:** Recent extension of the Haynesville/Bossier shale gas play north and west of the historic Louisiana–East Texas core, primarily across Robertson, Madison, Brazos, Grimes, and Leon counties in East-Central Texas.
- **Comstock Resources (NYSE: CRK) leads de-risking:** Discovery and early development work has demonstrated commercial gas production from deep Haynesville and Bossier intervals, often exceeding 15,000 feet true vertical depth.
- **Stacked-pay potential:** Many sections sit beneath active Austin Chalk horizontals, creating multi-zone development opportunities across Chalk, Buda, Eagle Ford-equivalents, Bossier, Haynesville, and Smackover formations.
- **Earlier-stage development:** The Western Haynesville remains less mature than the core Haynesville play in DeSoto, Sabine, and Caddo parishes of Louisiana, but validated horizontal completions confirm commercial viability.
- **Legacy lease complications:** Many existing leases were drafted before 2018–2020 for shallow conventional, Eagle Ford, or Austin Chalk targets and may include depth limitations, formation-specific Pugh clauses, or shallow vertical-only language ill-suited for deep Haynesville/Bossier development.
- **Legal review essential:** Mineral owners should consult a qualified Texas oil and gas attorney before signing any lease amendment, ratification, or new lease covering deep formations.
- **County-specific activity:** Robertson County serves as Comstock's activity core; Madison County is a step-out development area; Leon County shows active permitting; Brazos County combines Austin Chalk and deep gas; Grimes County is an active fairway.
- **No broker fees with Buckhead Energy:** As a direct buy-side firm, Buckhead Energy does not charge sellers broker commissions, listing fees, or auction premiums.
