Mineral rights are the legal ownership of the natural resources—oil, natural gas, coal, metals, and similar deposits—found beneath a piece of land. In the United States, these rights can be separated from ownership of the land’s surface, so one person can farm or build on a parcel while someone else owns everything underground. That split shapes everything else: who can drill, who collects the royalty check, who pays taxes on production, and who can lose their interest if they ignore it for too long.
How Surface and Mineral Ownership Get Separated
A property transaction can split ownership into two layers: a surface estate (the land you can see and walk on) and a mineral estate (the resources underneath). The split, called severance, happens through language in a deed. A seller might transfer the surface and include a reservation clause keeping the minerals, or a buyer might purchase only the minerals while the seller keeps the surface. Once severed, the two estates travel independently. The surface can change hands many times over the decades without affecting who owns the minerals below.
Severance can also happen at specific depths. A deed might grant one party the rights from the surface down to 12,000 feet and give another party everything below that depth. Because mineral and surface interests can pass through many owners, figuring out who owns what today means searching the chain of title—the recorded history of deeds, transfers, and reservations for the property.
Recording a mineral deed at the county recorder’s office places third parties on constructive notice that the interest exists. Without recording, a later buyer of the same minerals may have no way of knowing about a prior claim, and the result is often an expensive title dispute.
How to Tell Whether You Own the Minerals Under Your Land
Buying a piece of land does not guarantee that you own what lies beneath it. Start with your own deed. Language such as “together with all mineral rights” suggests the minerals came with the surface, while “mineral rights reserved” means a prior owner kept them. A deed that conveys “fee simple” without any mineral reservation may convey both estates, but an earlier deed in the chain could have severed the minerals long before your purchase.
The next stop is the county recorder’s office where the property sits. Ask for the chain of title and read through the recorded deeds, leases, and transfers in sequence. That history will show whether anyone along the way reserved or sold the minerals separately. In counties with decades of oil and gas activity, the record can be long and tangled.
For complicated histories, many owners hire a landman—a professional who researches mineral title and interprets deed language. Title companies can also produce ownership reports. A professional title search costs something, but almost always less than discovering a title defect after signing a lease or closing a sale.
Types of Mineral Interests
Mineral ownership can be carved into several distinct interests, which lets multiple parties hold different stakes in the same deposit. Each one combines income, control, and risk differently.
- A mineral fee interest is the most complete form of ownership. The holder controls the entire mineral estate, including the right to explore, lease to a drilling company, and collect all production revenue.
- A royalty interest is a share of production revenue, commonly between 12.5% and 25%, paid free of drilling and operating costs. It is passive: the holder receives a check but has no say in how or whether the minerals are developed.
- A non-participating royalty interest (NPRI) also pays a cost-free share of production, but the holder cannot negotiate or sign leases, collect bonus payments, or receive delay rentals. Leasing decisions stay with whoever holds the executive rights.
- An overriding royalty interest (ORRI) is a share carved out of a lease rather than out of the mineral estate itself. Because it is tied to the lease, an ORRI expires when the lease terminates. A standard royalty interest, by contrast, is permanent and survives lease changes.
- Executive rights are the authority to negotiate and sign oil and gas leases on behalf of the mineral estate. An owner can hold a mineral interest and still lack executive rights if those were separately conveyed to someone else.
What Actually Counts as a Mineral
Not everything beneath the surface belongs to the mineral estate. Common surface materials like sand, gravel, and topsoil typically belong to the surface owner, because extracting them would destroy the land surface itself. When a deed does not specifically list a substance, courts often apply an “ordinary and natural meaning” test: if the average person would consider the substance a mineral, it goes with the mineral estate.
Two newer questions sit at the edges of this definition. Pore space—the empty rock that is left after oil or gas is removed—belongs to the surface owner in the vast majority of states unless the deed says otherwise. Several states have passed legislation codifying that rule, which matters because pore space is increasingly valuable for underground carbon dioxide storage. Geothermal heat is harder to place. On federal land, the Geothermal Steam Act of 1970 treats geothermal resources as mineral reserves subject to federal leasing. On private land, classification varies, and few courts have directly addressed who owns it.
If Someone Else Owns the Minerals Under Your Land
Property law treats the mineral estate as the dominant estate. The mineral owner, or a company that leases from them, has an implied right to enter and use the surface as reasonably necessary to explore for and extract resources. That can include building access roads, drilling wells, laying pipelines, and conducting seismic testing.
The surface owner keeps the right to live on, farm, or otherwise use the land, but cannot block legitimate access. If a surface owner interferes with authorized operations, the mineral owner can seek a court order or sue for damages. To head off conflict, the parties can negotiate a surface use agreement that spells out where equipment goes, what gets restored afterward, and what the surface owner is paid for the disruption.
The accommodation doctrine, recognized in many oil- and gas-producing states, softens the mineral owner’s dominance. It requires the mineral owner or lessee to adopt a reasonable alternative method of extraction when the proposed operations would destroy or substantially impair an existing surface use and industry-standard alternatives exist. If a rancher has irrigated crops on a parcel and the drilling company could place its well pad elsewhere without significantly increasing cost, the doctrine may require the company to move.
Leasing Your Mineral Rights
Most mineral owners do not drill wells themselves. They lease their rights to an energy company in exchange for compensation that usually comes in several forms.
The lease bonus is a one-time, upfront payment made when the lease is signed. Bonus amounts vary widely with location, resource potential, and market conditions. Delay rentals are annual payments the lessee makes to keep the lease active during the primary term if no drilling has begun. Stop paying delay rentals without starting operations, and the lease typically expires.
The habendum clause divides the lease into two periods. The primary term, usually three to five years, gives the lessee time to explore and begin drilling. If the lessee establishes production before the primary term runs out, the lease enters its secondary term, which lasts as long as production continues. A gap in production longer than a set period, often 90 consecutive days, can terminate the lease.
A shut-in royalty clause protects the lease when a well has been drilled but no market exists for the gas. The lessee makes a nominal payment to the mineral owner, and the lease stays in effect as if the well were producing. Without the clause, a completed but unmarketable well could cause the lease to lapse.
What Happens When a Neighbor Drills
Oil and gas flow underground toward areas of lower pressure, crossing property lines along the way. The rule of capture—a longstanding common-law doctrine—says that whoever brings oil or gas to the surface through a well on their own land owns it, even if the resource migrated from beneath a neighbor’s property. Courts adopted the rule because tracing the exact origin of a fluid molecule underground is practically impossible.
The rule rewards speed. If your neighbor starts drilling, you have every incentive to drill an offset well on your own land before your resources drain away. The result can be overproduction, waste, and more wells than the formation needs.
To curb those effects, most states recognize correlative rights: each mineral owner’s reasonable opportunity to recover the oil and gas beneath their own land without being forced to drill unnecessary wells. State agencies enforce correlative rights through conservation regulations. One of the most significant tools is forced pooling, also called compulsory unitization. Most state oil and gas regulators can combine neighboring mineral interests into a single drilling unit when owners cannot reach a voluntary agreement.1Bureau of Land Management. Forced-Pooling Requests A non-consenting owner in a forced-pooling state typically still receives a share of production but may face penalties or reduced royalties compared with owners who participated voluntarily.
Taxes on Royalties and Sales
Mineral income is taxable at the federal level, and the rules differ depending on whether you receive ongoing royalties or sell the rights outright.
Royalty Income
Royalty payments are taxed as ordinary income on your federal return. Any payer who sends you at least $10 in royalties during the year must report that amount to the IRS on Form 1099-MISC.2Internal Revenue Service. About Form 1099-MISC, Miscellaneous Information If your modified adjusted gross income exceeds $200,000 ($250,000 for married couples filing jointly), royalty income is also subject to the 3.8% Net Investment Income Tax.3Internal Revenue Service. Questions and Answers on the Net Investment Income Tax Those thresholds are not indexed for inflation.
Percentage Depletion
Because minerals are a finite resource, the tax code allows a deduction called percentage depletion, similar in concept to depreciation for buildings. Independent producers and royalty owners can deduct 15% of gross income from domestic oil and gas production, as long as their average daily output does not exceed 1,000 barrels of oil or the natural gas equivalent.4Office of the Law Revision Counsel. 26 U.S. Code 613A – Limitations on Percentage Depletion in Case of Oil and Gas Wells Large integrated oil companies generally cannot use percentage depletion and must instead calculate cost depletion based on their actual investment in the property.
Selling the Rights
If you sell your mineral rights outright, the profit is treated as a capital gain. Rights held for more than one year qualify for long-term capital gains rates, which for 2026 are 0%, 15%, or 20% depending on your taxable income. The 3.8% Net Investment Income Tax can apply on top of the 20% rate for high-income sellers.3Internal Revenue Service. Questions and Answers on the Net Investment Income Tax
Inherited Rights
When you inherit mineral rights, the tax basis resets to fair market value on the date of the decedent’s death. This stepped-up basis can wipe out most or all of the taxable gain if you sell soon after inheriting at a price close to that value.5Internal Revenue Service. Publication 551 (12/2025), Basis of Assets Royalty income you receive after inheriting is still taxed as ordinary income going forward.
State Severance Taxes
In addition to federal income tax, most oil- and gas-producing states impose a severance tax on extracted resources. Rates range from zero in some states to as high as 35% and may vary with the type of resource, the commodity price, or the volume produced. The drilling company typically pays the severance tax, but the economic burden can reduce the royalty owner’s effective income.
Dormant Mineral Acts: Use It or Lose It
In roughly a dozen states, mineral rights that sit unused for a long enough period can be declared abandoned and returned to the surface owner. Dormant mineral acts exist to clear title and keep “orphaned” mineral interests from blocking land development indefinitely.
The required period of inactivity runs from 20 to 30 years depending on the state. During that window, the mineral owner has to take some affirmative step to keep the rights alive: recording a statement of claim, executing a lease, receiving royalty payments, or paying taxes on the interest. If no qualifying activity occurs and the surface owner follows the state’s notice and publication requirements, ownership of the minerals reverts to whoever owns the surface.
If you hold severed mineral rights in a state with a dormant mineral act, recording a statement of claim periodically at the county recorder’s office is the simplest way to preserve your interest. Miss the deadline, and you can lose the rights permanently, no matter what the resources underneath might be worth.
