The Western Haynesville is the recent extension of the Haynesville/Bossier shale gas play north and west out of the historic Louisiana–East Texas core. Discovery and de-risking work led principally by Comstock Resources (NYSE: CRK) has demonstrated commercial gas production from deep Haynesville and Bossier intervals at depths often exceeding 15,000 feet TVD across Robertson, Madison, Brazos, Grimes, and Leon counties in East-Central Texas.
The play remains in earlier-stage development relative to the Haynesville core in DeSoto, Sabine, and Caddo parishes of Louisiana, but multiple horizontal completions have validated commercial potential. Many sections in the corridor sit beneath active Austin Chalk horizontals, creating stacked-pay potential across the Chalk, Buda, Eagle Ford-equivalents, Bossier, Haynesville, and underlying Smackover.
Robertson County, TX — Comstock activity core

Many existing leases in the Western Haynesville corridor were drafted before 2018–2020 and were oriented toward shallow conventional, Eagle Ford, or Austin Chalk targets. They may include depth limitations, formation-specific Pugh clauses, or shallow vertical-only language that does not optimally address deep Haynesville/Bossier development. Always review your specific lease with a qualified Texas oil and gas attorney before signing any amendment, ratification, or new lease covering deep formations.
