Haynesville and Bossier Shale gas royalty review: East Texas and Northwest Louisiana
The Haynesville and Bossier Shale straddles the Sabine River across East Texas (Panola, Harrison, Shelby, San Augustine, and Nacogdoches counties) and Northwest Louisiana (DeSoto, Caddo, Bossier, Red River, Sabine, and Natchitoches parishes). Because Texas and Louisiana run on completely different pooling, unitization, and depth-severance rules, reviewing a Haynesville check stub starts with the state line.

In the Haynesville and Bossier Shale, horizontal wells are routinely drilled with 10,000- to 15,000-foot laterals at true vertical depths of 10,500 to 14,000+ feet. Reviewing an owner's royalty or buyout offer requires checking three basin-specific questions: (1) how cross-unit or allocation-well laterals split production across multiple units or surveys; (2) whether an older, shallower Cotton Valley or Travis Peak well holds the deep Haynesville rights by production (HBP) or whether a horizontal Pugh / vertical depth-severance clause released the deep interval; and (3) whether post-production gathering and CO₂-treating charges are permitted under the lease (or barred for unleased compulsory-unit owners in Louisiana under Self v. BPX Operating Co.).
1East Texas vs. Northwest Louisiana: two different unit systems
| Feature | East Texas (Panola, Harrison, Shelby, San Augustine, Nacogdoches) | Northwest Louisiana (DeSoto, Caddo, Bossier, Red River, Sabine) |
|---|---|---|
| Land survey system | Spanish/Mexican and Republic of Texas irregular Surveys and Abstracts. | Public Land Survey System rectangular 640-acre Sections, Townships, and Ranges. |
| How units are formed | Voluntary pooling under the lease's pooling clause (recorded Designation of Pooled Unit in the county clerk's office) or PSA / allocation well permits at the Railroad Commission. | Compulsory unitization orders issued by the Louisiana Office of Conservation (commonly 640-acre HA RA SU sectional units). |
| Unleased mineral owners | In an allocation well or unpooled tract, paid only if the lateral physically penetrates or produces from the tract. | Share proportionately by surface acreage inside the Commissioner's unit after well payout, with no post-production deductions under Self v. BPX Operating Co. (La. 2024). |
2Cross-unit laterals and allocation-well decimals
Early Haynesville wells were drilled inside a single 640-acre unit with a ~4,500-foot lateral. Modern Haynesville and Middle Bossier completions routinely use 10,000- to 15,000-foot laterals that cross two or three units (in Louisiana, cross-unit horizontal wells approved by Office of Conservation order; in East Texas, Production Sharing Agreement [PSA] or allocation wells permitted at the Railroad Commission).
When a well crosses multiple units or tracts, your unit decimal is multiplied by the Unit Allocation Factor, typically the length of perforated lateral from the first take point (FTP) to the last take point (LTP) inside your unit or tract divided by the total perforated lateral length across all units:
Well Decimal = (Your NMA ÷ Unit Acres) × Lease Royalty × (Perforated Feet in Your Unit ÷ Total Perforated Feet)
In a review, we pull the as-drilled directional survey and completion plat (RRC Form W-2 / G-1 and P-16 in Texas, or SONRIS cross-unit survey plat in Louisiana) to verify that the operator's allocation factor matches the actual perforated interval.
3Cotton Valley HBP vs. deep Haynesville rights
Across Panola, Harrison, Rusk, and Shelby Counties in Texas and Caddo, Bossier, and DeSoto Parishes in Louisiana, thousands of tracts were leased in the 1950s through 1990s for shallower Cotton Valley, Travis Peak / Hosston, or Pettet wells at 6,000 to 9,500 feet.
- No depth or Pugh clause: An old 1/8 royalty lease with no horizontal Pugh clause or vertical depth-severance clause may hold 100% of the deep Haynesville and Bossier rights (11,000 to 14,000 feet) at a 1/8 royalty as long as one shallow Cotton Valley well keeps producing in paying quantities.
- With a depth clause (or Louisiana horizontal/vertical Pugh clause): If the lease severed depths below "100 feet below the deepest producing perforation" at the end of the primary term, the deep Haynesville and Bossier formations may be unleased and open for a modern 1/4 royalty lease.
4Evaluating a Haynesville mineral or royalty buyout offer
Mailers offering to buy Haynesville minerals often arrive right after an operator files new multi-well horizontal permits, applies for a cross-unit order, or spuds a deeper Middle Bossier bench test on the same pad. Before weighing an offer:
- Calculate your exact Net Royalty Acres (NRA) on our home-page decline worksheet so you know what the buyer's offer equals in dollars per NRA.
- Check whether permits, DUCs (drilled but uncompleted wells), or undrilled infill locations in the Lower Haynesville or Middle Bossier are sitting on your unit.
