Mineral rights in Louisiana work differently from anywhere else in the country because Louisiana’s civil law tradition treats subsurface interests under its own Mineral Code rather than common-law property doctrine. Surface ownership and mineral ownership can be split, mineral interests can expire and revert if no one uses them for ten years, and the type of interest you hold — an active servitude or a passive royalty — controls what you can do with it, how it’s kept alive, and how it’s taxed.
Servitude or Royalty: The First Question to Answer
Louisiana recognizes two fundamentally different kinds of mineral interests, and confusing them is a costly mistake. A mineral servitude gives its holder the active right to enter the land, explore, drill, grant leases, and collect a share of bonuses and rentals. A mineral royalty is passive: the holder receives a share of production if and when it happens, but has no right to go onto the property or negotiate leases.
That distinction matters most for how each interest is kept alive. A mineral servitude expires through prescription of nonuse after ten years if no one exercises it. Good faith drilling operations, even unsuccessful ones, are enough to reset the clock and preserve a servitude.1Louisiana State Legislature. Louisiana Code RS 31:16 – Basic Mineral Rights; Status as Real Rights A mineral royalty has a harsher rule: only actual production within ten years keeps it alive. A dry hole won’t save a royalty.
When either type prescribes, the mineral rights revert to the surface owner, consolidating full ownership again. For a surface owner, this is often the path to recovering minerals they never explicitly purchased, so tracking the ten-year clock is worth doing carefully.
How Prescription Is Interrupted
Several activities can interrupt the ten-year clock on a servitude, including drilling operations, good faith testing, production, and operations conducted under a pooling or unitization order.2Justia Law. Louisiana Revised Statutes Title 31 – Mineral Code For a royalty, the bar is higher — production itself must occur within the ten years.
If a servitude was created 15 years ago and nothing qualifying happened during a ten-year window, that servitude has likely reverted by operation of law. Buyers who don’t check for this end up paying for something the seller no longer owns.
Acquiring Mineral Rights and Why Title Work Is Different
Mineral rights in Louisiana are governed by the Louisiana Mineral Code, enacted as Act 50 of 1974 and codified in Title 31 of the Revised Statutes.3Louisiana State Legislature. Louisiana Code Title 31 Mineral Code – Chapter 1 Preliminary Provisions Because surface and mineral ownership can be split, buying land in Louisiana does not necessarily mean buying the minerals under it. Mineral rights change hands through inheritance, direct purchase, or reservation in a sale — the seller keeps the subsurface while conveying the surface.
Title searches matter more here than in most states. Historical French and Spanish land grants, complex succession laws, and the possibility that older mineral servitudes have prescribed and reverted all create ambiguity. Every transaction affecting real property must be recorded in the parish conveyance records, and unrecorded interests generally cannot bind third parties who had no notice of them. Before buying mineral rights or signing a lease, a full examination of the chain of title in the parish records is the single best defense against paying for something that isn’t there.
Leasing Your Minerals
A mineral lease grants the lessee the right to explore and produce minerals in exchange for financial compensation to the landowner. Leases must be in writing and recorded in the parish conveyance records to be enforceable against third parties. Lease duration typically turns on a habendum clause: a fixed primary term, after which the lease continues only as long as the lessee produces in paying quantities. If production stops and no savings clause covers the interruption, the lease terminates automatically.
The Mineral Code also requires lessees to develop and operate the property as a reasonably prudent operator for the mutual benefit of both parties.4Louisiana State Legislature. Louisiana Code RS 31:122 The Louisiana Supreme Court reinforced that standard in Frey v. Amoco Production Co., 603 So.2d 166 (1992). A lessee who holds acreage without drilling when a prudent operator would may face cancellation of the undeveloped portions.
Royalty Rates
The traditional baseline royalty in Louisiana has been one-eighth, 12.5%, of production value, and some leases dating back decades still carry that rate. Modern leases often command more. A Legislative Auditor review of state mineral leases found average royalty rates of 21.9%, with individual leases ranging from 12.5% to as high as 61.6% depending on the region and play.5Legislative Auditor, State of Louisiana. State Mineral and Energy Board – Mineral Lease Royalty Rates Treat 12.5% as a floor, not a standard. Competitive areas like the Haynesville Shale regularly see rates above 25%.
Post-Production Cost Deductions
Louisiana is an “at the well” state for royalty calculations. Royalty is valued at the wellhead, after extraction costs but before transportation, processing, and marketing. Unless the lease says otherwise, the lessee can deduct a proportionate share of post-production costs — gathering, compression, treating, transportation — from the royalty check. Those deductions can substantially shrink what a royalty owner actually receives. Lease language that prohibits or limits post-production deductions is negotiable up front, and negotiating it there is far easier than litigating it later.
Royalty and Valuation Disputes
Royalty disputes often involve post-production cost deductions, disagreements over how production is valued, or claims that the operator has underpaid by using an affiliate’s below-market purchase price rather than true market value. Because Louisiana allows proportionate cost sharing at the wellhead by default, lease language matters enormously. Vague royalty clauses invite litigation; specific ones prevent it.
Forced Pooling if You Won’t Lease
Louisiana’s Commissioner of Conservation has authority to force the pooling of mineral interests within a drilling unit when voluntary agreements fail. Under RS 30:10, a mineral owner who refuses to lease or participate in a well can still have their minerals developed against their wishes.6Louisiana State Legislature. Louisiana Code RS 30:10 – Agreements for Drilling Units; Pooling Interests Compulsory pooling orders are issued after notice and hearing, on terms that must be just and reasonable.
Non-consenting owners who are force-pooled typically face a risk penalty. They receive their share of production, but the operator first recoups the non-consenter’s proportionate share of drilling and completion costs, often with a risk charge on top. A landowner who refuses to negotiate a lease may end up with significantly less than one who signed. In active drilling areas, ignoring a pooling notice is one of the most expensive things you can do.
Taxes on Mineral Income and Ownership
Severance Taxes
Louisiana imposes severance taxes on minerals extracted from the ground, and the rates vary by resource and, for oil, by when the well was completed. For oil produced from a well completed before July 1, 2025, the severance tax is 12.5% of its value at the point of production. For wells completed on or after that date, the rate drops to 6.5%.7Louisiana State Legislature. Louisiana Code RS 47:633 – Severance Tax; Rates; Administration The natural gas severance tax is adjusted annually based on a formula tied to gas prices. For the period from July 2025 through June 2026, the rate is 10.52 cents per thousand cubic feet.8Louisiana Department of Revenue. RIB 25-015 Natural Gas Tax Rate July 2025 June 2026
These rates affect the economics of marginal wells and, by extension, whether a lessee keeps operating or releases the lease back to you.
Ad Valorem Taxes
Mineral rights are also subject to ad valorem property taxes assessed by local parishes. The Louisiana Constitution requires property to be assessed at a percentage of fair market value, with the applicable percentage depending on classification.9Louisiana State Legislature. Louisiana Laws – Part II Property Taxation – Section 18 Ad Valorem Taxes Valuing mineral rights for property tax means estimating future production, remaining reserves, and current market prices, so these assessments are inherently debatable. Owners who believe an assessment is too high can challenge it through the parish board of review. Failure to pay ad valorem taxes can result in tax liens or eventual loss of the interest at a tax sale.
Plugging, Orphan Wells, and Surface Owner Liability
When a well stops producing, someone has to plug it and clean up the site. The owner of record is responsible for properly plugging and abandoning any well under the Commissioner of Conservation’s jurisdiction.10Cornell Law Institute. Louisiana Administrative Code Tit. 43 Section XIX-137 – Plugging and Abandonment The Commissioner can require operators to post a bond ensuring the work gets done, and inactive wells that aren’t covered by financial security must have it provided within specified deadlines.
The real-world problem is that operators sometimes go bankrupt or disappear, leaving behind orphan wells that no viable responsible party will plug. Louisiana addresses this through its Oilfield Site Restoration Program, which plugs orphan wells and restores sites to approximate pre-wellsite conditions. The program is funded entirely by fees on active oil and gas production and inactive wells paid by Louisiana operators, not by general tax revenue, and it generates roughly $8 million per year.11Department of Energy and Natural Resources. Oilfield Site Restoration (OSR) Program Even with that backstop, an orphan well on your property can create environmental headaches and delay redevelopment for years while you wait for the state to reach it. Choosing a reputable lessee up front is one of the few defenses a surface owner has against inheriting problems the operator was technically responsible for.
