Mineral Rights Title Search: How to Find the Owner
A mineral rights title search is how you find out, on paper, who actually owns the oil and gas under a tract. It works by tracing the chain of title through county clerk deed records, back to the original grant from the government. There is no national registry, so the answer always lives in the county where the land sits.

What a mineral rights title search actually does
A mineral rights title search answers one question: who owns the minerals under this specific tract, and in what fraction? It does that by reading every recorded document that touched the property, in order, from the first government grant to the most recent deed.
The reason it takes work is that minerals are usually severed from the surface. The person who owns the house, the farm, or the ranch above often owns little or none of the oil and gas below. The property tax roll tracks the surface; the minerals follow a separate paper trail of deeds, reservations, and probates. So the question "who owns the mineral rights to my property" almost never has the same answer as "who pays the property tax." If you are new to that split, our guide to what mineral rights are explains it from the ground up.
A title search produces three things: the current owner or owners, the exact fraction each one holds (measured in net mineral acres, not surface acres), and whether the minerals are currently under lease. Everything a buyer underwrites flows from those three facts.
Why there is no national mineral rights registry
People search for a single database of mineral owners and come up empty. That database does not exist, and it is worth understanding why, because it shapes how to find out who owns mineral rights anywhere in the country.
In the United States, real property records are kept at the county level. When someone sells, reserves, leases, or inherits minerals, the document is recorded with the county clerk (called the recorder, register of deeds, or county recorder in some states) where the land physically sits. There is no federal or even statewide office that consolidates all of it. The federal government keeps records only for federally owned minerals, which are leased through the Bureau of Land Management (BLM), not for the private mineral estate that makes up most of the producing basins.
This is why ownership is determined county by county, tract by tract. A company can aggregate those county records into a searchable index, and that is exactly what Mineral Eagle does across the oil and gas states. But the authoritative source is still the recorded instrument in the county clerk's office. Any index, ours included, points back to that record.
Tracing the chain of title from the patent
The heart of a mineral rights title search is the chain of title: an unbroken sequence of conveyances connecting today's owner back to the original source of title. In most states that source is the patent, the first grant of the land out of the public domain from the federal government, the state, or in Texas the sovereign and earlier Spanish or Mexican grants.
Each link in the chain has to connect cleanly to the next. The searcher reads each document and asks the same questions:
- What was conveyed? The whole tract, or only the surface, or only a fraction of the minerals?
- What was reserved? Sellers frequently kept a fraction of the minerals when they sold the land. Those reservations stack up over a century.
- Did anything pass by death? An estate that went through probate, or that did not, can split a single interest among many heirs.
A gap, an ambiguous reservation, or a missing probate is where a deal stalls. The output of this work is often written up as a runsheet: a chronological list of every instrument affecting the tract, with grantor, grantee, date, recording reference, and what each one did to the mineral estate. From the runsheet, the searcher builds the final ownership picture and the fractional math.
Mineral deeds, warranty deeds, and severance language
Most of the confusion in a title search comes from the documents themselves, because several look similar but do very different things. The deed type and its exact wording control the result.
- Warranty deed. The common instrument for transferring real property. A general warranty deed conveys the land with a promise that title is clear. On its own it usually conveys both surface and minerals, but it can carve them up. The fine print matters more than the title at the top of the page.
- Mineral deed. Conveys the minerals themselves, in whole or in fraction, separately from the surface. This is the instrument that creates or transfers a severed mineral interest.
- Royalty deed. Conveys only a share of future production revenue, not the minerals or the right to lease. A royalty owner can receive checks without having any say in whether the tract is leased.
The decisive part is the severance language, the clause that reserves or conveys minerals. A reservation such as "grantor reserves an undivided one-half of all oil, gas, and other minerals" means the seller kept half the minerals even though the deed conveyed the whole surface. Reading that language correctly, and tracking it through every later deed, is the skill at the center of the search. Small differences in wording change who owns what, which is why tracking severance language carefully through every later deed is the core skill of the search.
How to find out who owns mineral rights, step by step
Here is the practical sequence for how to find out who owns mineral rights on a given tract. You can do the early steps yourself; the later ones often call for a professional.
- Pin down the legal description. You need the tract's legal description (abstract and survey in Texas, or section-township-range in most other states), not just a street address. The county appraisal or assessor record is a good place to start for the surface owner and the legal description.
- Go to the county clerk's land records. Search the grantor-grantee index in the county where the land sits. Many counties offer online access; others require a visit or a copy request. You are looking for every deed, reservation, lease, and probate touching that legal description.
- Build the chain back from the patent. Work forward from the original grant, noting every conveyance and reservation, or work backward from the current surface owner. Either way, the links must connect.
- Check the state regulator for activity. Permits, well status, and production tell you whether the minerals are leased and producing. In Texas that is the Railroad Commission of Texas (RRC), the state's oil and gas regulator, which publishes permits, well status, and production.
- Resolve the fractions. Convert every reservation and conveyance into net mineral acres so you know exactly how much each party owns.

Runsheets, landmen, and abstract companies
When the chain gets long or tangled, the work goes to professionals who do it for a living.
- Landmen research title, build runsheets, and prepare ownership reports. A landman who delivers a formal opinion of who owns what, with the supporting documents, is doing the core of a mineral title search. Many buyers keep a landman on call for exactly this.
- Abstract companies compile an abstract of title, a certified package of every recorded instrument affecting a tract. In some states the abstract is the standard input an attorney relies on to issue a title opinion.
- Oil and gas attorneys read the runsheet or abstract and issue a title opinion, a legal conclusion about ownership and the fractions. For a purchase of any size, a drilling-title or division-order opinion from a qualified attorney is the document buyers and operators actually rely on.
The hand-offs matter. A landman or abstractor assembles the record; an attorney renders the legal conclusion. Title questions carry real legal and financial consequences, so when ownership is unclear or money is on the line, have the chain reviewed by an oil and gas attorney rather than relying on a self-serve search alone.
State-by-state record access: Texas, Oklahoma, New Mexico
The method is the same everywhere, but where you look and what you find online differs by state. A buyer always works two sources at once: the county clerk's deed records for ownership, and the state oil and gas regulator for permits, well status, and production.
| State | Ownership records | Regulator for activity |
|---|---|---|
| Texas | County clerk, indexed by abstract and survey; online access varies widely by county | Railroad Commission of Texas (RRC) |
| Oklahoma | County clerk, indexed by section-township-range | Oklahoma Corporation Commission (OCC) |
| New Mexico | County clerk, plus a large share of federal minerals leased through the BLM | New Mexico Oil Conservation Division (OCD) |
A few practical notes. A texas mineral rights search runs through the county clerk in each of Texas's 254 counties, and online availability ranges from a full searchable index to nothing but an in-person book. New Mexico has a heavy federal footprint, so a meaningful number of interests are federal and trace through the BLM rather than a private chain. Oklahoma's pooling and forced-pooling history can make the leasing picture more complex than the deed record alone suggests. State-specific detail, including the county-access picture and the regulator lookups, lives on our Texas mineral rights page.
Online tools and their limits
Online resources have made the first pass faster, but it is important to know what they can and cannot tell you.
- County online indexes are the closest thing to the source of truth, but coverage is uneven. Some counties post fully searchable grantor-grantee indexes with images going back decades; others have only recent records or nothing online at all.
- Appraisal and assessor sites identify the surface owner and the legal description. They generally do not reflect severed mineral ownership, so they are a starting point, not an answer.
- Regulator databases like the RRC, OCC, and OCD show permits, well status, and production. They tell you about activity and operators, not about who owns the minerals.
- Aggregated platforms pull county ownership, permits, well production, and lease data into one searchable place, which compresses days of cross-referencing. This is the layer Mineral Eagle's data sits in.
The honest limit applies to all of them: any index is only as current and complete as the records behind it, and an index is not a legal opinion. A tool is excellent for finding leads, narrowing a search, and sizing an opportunity fast. It does not replace the certified chain of title and the attorney's opinion you rely on to close. Treat online results as the start of a search, then confirm the chain in the deed records before you commit money.
When to hire a professional
You can run the early steps yourself: identify the surface owner, pull the legal description, and skim the county index to see whether the minerals were obviously severed. That is enough to decide whether a tract is worth chasing.
Bring in a landman, abstractor, or oil and gas attorney once any of these is true:
- Money is changing hands. Any purchase, not just a large one, deserves a professional title review before closing.
- The chain has gaps, ambiguous reservations, or a probate that was never completed.
- The interest passed through one or more estates. Inherited interests fracture quickly, and the math gets hard. Our inherited mineral rights guide covers that path.
- You need a number you can defend, which depends on knowing the exact net mineral acres. See the mineral rights value guide for how acreage drives price.
The cost of a professional title search is small next to the cost of buying the wrong fraction, or buying an interest the seller did not actually own. For anything beyond a casual check, the title opinion is the document that protects you, and only an oil and gas attorney can issue it. None of the above is legal or tax advice; confirm your specific situation with a qualified attorney and a CPA.
Frequently asked questions
How do I find out who owns the mineral rights to my property?
Start with the legal description and the surface owner from the county appraisal record, then search the county clerk's land records in the county where the tract sits. Trace every deed, reservation, and probate from the original patent forward. Because severances and fractional interests are easy to miss, a landman or oil and gas attorney can run the title search and tell you exactly who owns what and in what fraction.
Is there a national database of mineral rights owners?
No. Mineral ownership records are kept at the county level by the county clerk where the land sits, and there is no federal or statewide registry of private mineral owners. The federal government keeps records only for federally owned minerals leased through the BLM. Aggregated platforms can index many counties at once, but the authoritative source is always the recorded deed in the county.
How much does a mineral rights title search cost?
It depends on how long and tangled the chain is and who does the work. A basic search you run yourself in an online county index costs nothing but time. A landman or abstractor preparing a runsheet, or an attorney issuing a title opinion, charges by complexity. For any purchase the cost is small next to the risk of buying the wrong fraction or an interest the seller did not own.
What is the difference between a mineral deed and a warranty deed?
A warranty deed is the common instrument for transferring real property and usually conveys both surface and minerals unless it says otherwise. A mineral deed conveys only the minerals, in whole or in fraction, separately from the surface. The deciding factor is the severance language inside the document, not the label at the top, so each deed has to be read carefully during a title search.
Can I do a mineral rights title search myself?
You can do the early steps: find the legal description, identify the surface owner, and skim the county grantor-grantee index for obvious severances. That is enough to decide whether a tract is worth pursuing. But building a defensible chain of title, resolving fractions, and confirming ownership before money changes hands is work most buyers hand to a landman or oil and gas attorney.
Where do I search for Texas mineral rights ownership?
A Texas mineral rights search runs through the county clerk in the county where the tract sits, indexed by abstract and survey. Online access varies by county, from a full searchable index to in-person books only. For activity, the Railroad Commission of Texas (RRC) shows permits, well status, and production. Ownership and activity are separate sources, so check both before drawing conclusions.
