Do Mineral Rights Expire in Wyoming?
Do mineral rights expire in Wyoming? No Wyoming statute was found that ends or transfers a severed mineral interest for nonuse. The Wyoming Marketable Title Act (W.S. 34-10-101 to 34-10-109, 40 year chain of title) states that it shall not be applied to bar or extinguish any interest in minerals, including oil and gas.
No statute found Researched and checked by American Mineral Registry by searching the text it could read, which turned up no statute on this point; review completed October 1, 2026. Reference research, not legal advice.

How the rule works
No dormant mineral statute identified; the marketable title act excludes minerals. No Wyoming statute was found that ends or transfers a severed mineral interest for nonuse. The Wyoming Marketable Title Act (W.S. 34-10-101 to 34-10-109, 40 year chain of title) states that it shall not be applied to bar or extinguish any interest in minerals, including oil and gas. A 2003 bill that would have created an abandoned mineral interest procedure at W.S. 34-10-201 to 34-10-210 failed in the House and is not in the current code.
Scope
- Interests covered
- Not applicable. The marketable title act exclusion covers any title, estate or interest in minerals and related development, mining and production rights and easements.
- Minerals covered
- Not applicable. The exclusion names minerals generally, including oil, gas and other hydrocarbons, and timber.
- Exceptions
W.S. 34-10-108(a)(iv): the Marketable Title Act shall not be applied to bar or extinguish any title, estate or interest in minerals or related rights and easements
W.S. 34-10-104(a)(v): marketable record title is subject to the exceptions in 34-10-108(a), including mineral interests
- Enactment and amendments
- No dormancy statute. 2003 HB0176 (Termination of mineral interest) failed in Committee of the Whole and was indefinitely postponed on January 30, 2003. The enactment date of the Marketable Title Act is not shown in the official title PDF.
- What AMR searched
- Downloaded all 42 title PDFs of the Wyoming Statutes from wyoleg.gov/statutes/compress/ (created May 9, 2026) and searched the full text for: dormant mineral, abandoned mineral, severed mineral, mineral interest, mineral estate, unknown owner, abandon. Title 30 (Mines and Minerals) and Title 34 (Property) read for structure. Found: Marketable Title Act 34-10-101 to 34-10-109 with a mineral exclusion; 34-2-135 (tax deed curative act does not apply to tax deeds covering only severed minerals); 34-24-117 (Uniform Unclaimed Property Act: mineral proceeds unclaimed for more than three years, and the owner's underlying right to receive them, are deemed abandoned and become subject to state custody; custody of proceeds, not a transfer of the mineral interest). Checked the 2003 bill HB0176 on wyoleg.gov (failed). Case law was not reviewed.
What “none found” means. AMR searched the official code for a dormant mineral, abandonment, lapse or forfeiture statute and found none. That does not mean a mineral interest can never be lost: deeds, title defects, tax sales, adverse possession and other rules can still affect ownership, and they are outside this review.
Dates and what they mean
There is no statutory nonuse period to calculate for this jurisdiction under the rules AMR reviewed.
No statutory lapse was identified, so there is no lapse or deadline date for Wyoming.
Deceased or unlocated owner
Partly checked What the law of Wyoming says when the owner of record has died, is unknown, or cannot be found. It sets out the questions; it does not decide who owns an interest, whether a notice was valid, or whether an interest ended.
Why only partly checked. Titles outside 1, 30 and 34 were not searched for a court trust or receiver.
No Wyoming statute ending a severed mineral interest for nonuse was found, and the Marketable Title Act expressly may not be applied to bar mineral interests, so a deceased, unknown or unlocated owner's mineral title is not lost through any dormancy procedure in the provisions read. What Wyoming does address is the money: production proceeds that cannot be paid for any reason go into an interest bearing escrow, become unclaimed property if undeliverable for three years, and mineral proceeds unclaimed for three years are deemed abandoned for unclaimed property custody. No court trust or receivership for missing mineral owners was found in titles 1, 30 or 34.
- Owner of record has died
- Not addressed in the provisions read; probate and quiet title may apply and were not reviewed.
- Current owner unknown
- Not named; production proceeds that cannot be paid for any reason are escrowed (30-5-302).
- Owner known but cannot be found
- Not named; proceeds escrowed (30-5-302), then unclaimed property after three years undeliverable (30-5-302, 34-24-117).
How the nonuse rule treats these owners Statute
No nonuse mechanism found; the Marketable Title Act shall not be applied to extinguish mineral interests.
Statute
The Wyoming Marketable Title Act may not be applied to bar or extinguish interests in minerals, including oil and gas. W.S. 34-10-108(a)(iv)
“To bar or extinguish any title, estate or interest in and to any timber or any minerals (including without limiting the generality of that term, oil, gas and other hydrocarbons)”
Scope: Introduced by 34-10-108(a): the act shall not be applied, notwithstanding a failure to file a notice of claim. Applies to all mineral owners regardless of status.
Heirs, devisees and successors Not addressed in the provisions read
The provisions read do not address heirs, devisees or successors.
Search required to find the owner Not addressed in the provisions read
No search requirement appears in the provisions read.
Who gets notice, and how Not addressed in the provisions read
No notice to mineral owners is required by the provisions read, since none ends a mineral interest.
Notice by publication Not addressed in the provisions read
No publication provision in the provisions read.
How the owner responds or preserves Not addressed in the provisions read
Not applicable to any title ending mechanism in the provisions read; claims to escrowed or unclaimed funds follow the escrow and unclaimed property statutes, not reviewed in detail.
Court, receivership or trust for missing owners Statute
Escrow of unpayable production proceeds (30-5-302) and unclaimed property treatment of mineral proceeds (30-5-302, 34-24-117). No court trust, receivership or leasing mechanism for missing mineral owners found.
Statute
A delay in identifying a person entitled to production proceeds does not delay payment to everyone else. W.S. 30-5-302
“Any delay in determining any person legally entitled to an interest in the proceeds from production shall not affect payments to all other persons entitled to payment.”
Scope: Oil and gas production proceeds payable by a lessee, operator, purchaser or other responsible party.
Proceeds that cannot be paid on time for any reason must be deposited in an interest bearing escrow account at a Wyoming insured institution. W.S. 30-5-302
“In instances where payment cannot be made for any reason within the time limits specified in W.S. 30-5-301(a), the lessee or operator, purchaser or other party legally responsible for payment shall deposit all proceeds credited to the eventual interest owner to an escrow account in a federally insured bank or savings and loan institution in Wyoming”
Scope: Covers proceeds of owners who cannot be paid for any reason, which as the text reads includes deceased, unknown and unlocated owners; the statute does not name those categories.
Escrowed proceeds the escrow agent cannot deliver within three years become unclaimed property. W.S. 30-5-302
“If the escrow agent is unable to deliver the payment to the legally entitled person within three (3) years from the end of the month in which the escrow agent first received notice of the person legally entitled to the payment, the payment shall be considered unclaimed for purposes of W.S. 34-24-101 through 34-24-139.”
Scope: Escrowed production proceeds. Concerns the money, not title to the mineral interest.
Mineral proceeds unclaimed for more than three years, and the owner's right to receive them, are deemed abandoned for unclaimed property purposes. W.S. 34-24-117(a)
“Any sum payable as mineral proceeds that has remained unclaimed by the owner for more than three (3) years after it became payable or distributable and the owner's underlying right to receive those mineral proceeds are deemed abandoned.”
Scope: Unclaimed property act custody of mineral proceeds, subject to the conditions in 34-24-117(b). The provisions read do not say this transfers title to the mineral interest itself; the rest of the unclaimed property act was not reviewed.
What a title review must establish
- Is any owner's share in a 30-5-302 escrow or reported as unclaimed property (special_mechanism)?
- If the record owner is deceased, how was title passed, since no Wyoming dormancy procedure was found to shift it (succession, mechanism)?
Dates. Escrowed proceeds become unclaimed if not delivered 'within three (3) years from the end of the month in which the escrow agent first received notice of the person legally entitled to the payment' (30-5-302). Mineral proceeds unclaimed 'for more than three (3) years after it became payable or distributable' are deemed abandoned (34-24-117(a)). These periods concern money, not mineral title. The rule finder does not calculate this period.
What AMR searched. Read: W.S. 34-10-108 (title34.pdf), 30-5-301 to 30-5-303 (title30.pdf), 34-24-117 (title34.pdf). Full text of titles 1, 30 and 34 (2026 title PDFs) searched for unknown, unlocat, whereabouts, cannot be located, missing, together with owner, interest, heir or mineral; only a unitization application provision and unclaimed property provisions matched. The October 2026 review's finding that 2003 HB0176 (abandoned mineral interests) failed was not re-read. Not searched: title 2 (probate and trusts). No Wyoming case law searched for, since no owner status mechanism was found. A point marked not addressed means only that the provisions read do not address it; probate, quiet title and other general procedures may still apply and were not reviewed.
Not settled by this review.
Whether any Wyoming statute outside titles 1, 30 and 34, for example in title 2, provides a court trust or receiver for missing mineral owners.
How unclaimed property custody under 34-24-117 interacts with later leasing of a missing owner's interest.
Checked October 6, 2026. Also in the dormant mineral rule finder.
Forced pooling
Official text cited Yes. W.S. 30-5-109(f) lets the Oil and Gas Conservation Commission, in the absence of voluntary pooling and after notice and hearing, enter an order pooling all interests in a drilling unit on the application of any interested person, on just and reasonable terms. A pooling order expires after 12 months if operations have not commenced.
Surface damages
Official text cited Yes. W.S. 30-5-401 to 30-5-410 (entry to conduct oil and gas operations) require notice to surface owners, condition entry on consent, a surface use agreement, a waiver or a bond, and require the operator to pay the surface owner for loss of production and income, loss of land value and loss of value of improvements. A surface owner gives notice of damages within two years of discovery and may sue if no acceptable offer is made.
Taxes
Broad personal income tax: no. Wyoming levies no personal state income tax, so an individual's royalty income is not taxed by the state. Official text cited Source and notes.
Severance or production tax. 6 percent of the value of oil and gas; 4 percent for stripper and tertiary oil. Official text cited Full record: rates, exemptions, royalty owner share and sources.
Not tax advice. Rates change and the cited source controls.
Sources for the dormant mineral rule
Each source was read on the date shown. Where an official site was not available, the official page was read through a dated Internet Archive copy and that is stated.
- W.S. 34-10-108(a)(iv) (this act 'shall not be applied')
“To bar or extinguish any title, estate or interest in and to any timber or any minerals (including without limiting the generality of that term, oil, gas and other hydrocarbons) and any development, mining, production or other rights or easements related thereto”
- 2003 HB0176, Termination of mineral interest, journal digest (not enacted)
“1/30/2003 H Failed CoW; Indef Postponed”
- W.S. 34-24-117(a)
“Any sum payable as mineral proceeds that has remained unclaimed by the owner for more than three (3) years after it became payable or distributable and the owner's underlying right to receive those mineral proceeds are deemed abandoned.”
Open questions for a specialist
This review did not settle these points. They are where a Wyoming title attorney or landman should look first.
Wyoming case law on abandonment of severed mineral interests and on adverse possession of minerals was not reviewed.
Whether the unclaimed property transfer of the 'underlying right to receive' mineral proceeds has any effect on title was not researched; the text reads as custody of proceeds.
Common questions
Can mineral rights lapse in Wyoming?
A search of Wyoming’s official code found no dormant mineral, lapse or forfeiture statute, so an interest does not lapse through nonuse under a statute of that kind. Deeds, tax sales and title rules can still affect ownership.
Does Wyoming allow forced pooling?
Yes. Wyoming has a forced pooling statute, summarized with its citation under Forced pooling above.
Does Wyoming require payment for surface damage?
Yes. Wyoming has a statute requiring operators to compensate surface owners, summarized with its citation under Surface damages above.
What changed
The June 2026 edition listed Wyoming as Does not lapse, lapse period none. Release 2026.10 replaced that entry with the reviewed rule above, and retired the June risk score and ranking for every state. Release 2026.10.1 added the deceased or unlocated owner section. See all changes.
