Mineral rights maps can show wells, permits and activity near a tract, but a well location does not establish who owns the minerals. County land records and ownership documents answer a different question. Use the state sources below for activity, and consult a qualified professional about ownership.
A search for a mineral rights map may mean two things: finding who owns an interest, or finding wells near land you already know about. Keeping those questions separate makes the results more useful. A nearby well, an operator name or a surface parcel is not proof of private mineral ownership.
What a mineral rights map can — and cannot — tell you
Check the purpose and legend of each map. Well locations, permits, producing status and unit boundaries describe different parts of oil and gas activity; available layers vary by agency. A map label naming an operator identifies the company associated with a well record, not every person with an interest in the minerals.
Map location is context, not an ownership determination. The Texas Railroad Commission warns that its GIS locations are approximate and are not a ground survey or authoritative legal record.
Official state maps and mineral-owner resources
These links lead to public agency tools or their instructions. Public access does not mean every record is digitized, every document is free, or every map layer is complete. Read the source date and the agency’s limitations before using a result.

Where county ownership records fit
Deeds and other recorded instruments can contain information about mineral interests. The relevant office is commonly called the county clerk, recorder or register of deeds. Online availability, indexing and document-copy fees vary. A surface parcel map or an appraisal entry can be a research lead, but neither by itself establishes the current ownership of a severed mineral interest.
A legal description, county, document reference, well name or API number can help distinguish similarly named records. Identifiers from a royalty statement describe the payor’s records and may differ from agency identifiers. Questions about title, inheritance or the meaning of a recorded instrument belong with a qualified attorney or title professional.
Our mineral ownership flowchart organizes starting points for owners with a deed, inherited records or royalty statements. The mineral rights map overview explains common map layers and links to state and county resources; it is an educational guide, not an interactive ownership database.
Connect the records to reported activity
The Texas drilling activity report and Oklahoma drilling activity report provide activity context. Check each report’s source date, reporting window and coverage before comparing it with your documents. A permit or drilled well does not establish that production has begun or that a particular owner is owed a payment.

Considering an inquiry about your minerals?
You can start a mineral-rights inquiry when you want to discuss a possible sale. A map screenshot can provide context, but it does not replace the records describing the interest.
When to Hire Help
If the records are tangled — multiple generations of heirs, missing probates, name changes — a professional landman or mineral title company can run the chain of title properly. If the goal is selling, a direct buyer does this research as part of valuation: Buckhead Energy verifies ownership from the county records on every offer we make, at no cost to the owner.
Key Takeaways
- A well map and a mineral-ownership record answer different questions.
- Agency maps differ in coverage, source dates and available layers.
- A well operator or surface parcel owner is not necessarily the mineral owner.
- An appraisal entry or empty search result does not determine ownership.
- Consult a qualified professional about title and document interpretation.
Frequently Asked Questions
Is there a free mineral rights ownership map?
Public well maps are useful research tools, but a well location alone does not identify private mineral owners. Read the map’s purpose and layers. County recorded documents and professional title review address ownership; access and document-copy fees vary by county.
Where can I look up mineral rights in North Dakota or Montana?
North Dakota DMR’s mineral-owner page explains activity searches and links to county-recorder resources. Montana’s Board of Oil and Gas Conservation links to its GIS and well-data tools. Use activity records as context and consult a qualified professional about ownership documents.
Does a county appraisal record prove I own the minerals?
An appraisal entry can be a research lead, but it is not by itself a determination of current mineral ownership. Surface ownership and mineral ownership can differ, and records may need clarification from the relevant office or a qualified title professional.
Does a well on a map mean I should receive royalties?
No. A well’s location or reported production does not establish a particular person’s ownership or payment entitlement. A royalty statement, ownership documents and the payor’s records address different parts of that question.
Will Buckhead Energy research my ownership for me?
Yes — verifying your interest in the county records is part of preparing every written offer, at no cost and with no obligation to sell.
