A public record of who owns what is under the ground

Colorado mineral rights

Verified
Jul 29 2026

The short answer

Colorado severs minerals freely, treats a severed mineral interest as its own estate in real property, and has no dormant mineral statute, so an interest split off a century ago is still owned by somebody today and no period of non use will lapse it. Ownership is recorded with the county clerk and recorder in the county where the land sits, and a chain of title is traced through that county's grantor and grantee indices.

The part most often stated wrongly is what an operator owes the surface owner. Colorado's Supreme Court uses the old label of a dominant mineral estate and then qualifies it, and the statute requires accommodation rather than mere reasonable use.

Checked against the sources named below on .

Can a Colorado mineral interest be lost by not using it?

No. Colorado has no dormant mineral interest act, so there is no period of non use that lapses a severed mineral interest, no notice of intent to preserve to file, and no notice of lapse to record. Losing one takes a conveyance, a tax sale, or adverse possession of the minerals themselves, and possessing the surface is not possessing the minerals once the estate has been severed. The rules below give the sources for each of those points, including the one we could only partly confirm.

A severed mineral interest is its own estate

A conveyance that severs the minerals from the surface creates a separate and distinct estate in Colorado, and while in place minerals are real property.

severance

Title commitments must warn that the minerals were severed

verified

C.R.S. § 10-11-123

Colorado requires a title insurance commitment to state when a mineral estate has been severed, and to warn that the mineral owner may be able to enter and use the surface without the surface owner's permission.

That such mineral estate may include the right to enter and use the property without the surface owner's permission.
read from Public.Law, Colorado Revised Statutes, current through Fall 2025

Checked July 25, 2026. Full text of the section read at colorado.public.law, current through Fall 2025. The section also requires the commitment to state "that a mineral estate has been severed, leased, or otherwise conveyed from the surface estate".

Whether a mineral interest can lapse

dormancy

Colorado has no dormant mineral statute

verified

C.R.S. §§ 38-42-101 to 38-42-106 (Article 42, Oil, gas, & mining leases)read from Public.Law, Colorado Revised Statutes, current through Fall 2025

Colorado has no dormant mineral interest act: no period of non-use lapses a severed mineral interest, and there is no notice of intent to preserve and no notice of lapse to record.

Checked July 25, 2026. Title 38, Article 42 was read section by section at colorado.public.law and is titled "Oil, gas, & mining leases" rather than severed mineral interests. It contains six sections and none is a dormancy or lapse provision: 38-42-101 lease with option to purchase, -102 option void when, -103 title form, -104 lease surrendered when, -105 actions for surrender of lease and damages, -106 record of lease no longer notice unless affidavit recorded. The nearest analogue is lease dormancy rather than mineral-interest dormancy: § 38-42-106 makes a recorded lease stop operating as notice unless an extension affidavit is recorded within six months after the primary term, for leases after March 28, 1967. No dormant mineral act was found in the CRS or in the legislature's bill records.

Where ownership is recorded, and how a chain of title is searched

Two statutes answer this between them. The first says where an instrument goes and what happens if it is never recorded. The second is the index a title search actually runs on.

records

Ownership is recorded with the county clerk and recorder

verified

C.R.S. § 38-35-109(1)

A deed or reservation affecting Colorado real property is recorded in the office of the county clerk and recorder for the county where the land sits, and an unrecorded instrument loses to a later party who records first without notice of it.

All deeds, powers of attorney, agreements, or other instruments in writing conveying, encumbering, or affecting the title to real property, certificates, and certified copies of orders, judgments, and decrees of courts of record may be recorded in the office of the county clerk and recorder of the county where such real property is situated
read from Public.Law, Colorado Revised Statutes, current through Fall 2025

Checked July 29, 2026. Subsection (1) read in full at colorado.public.law, current through Fall 2025, then cross-checked word for word against codes.findlaw.com, which marks its copy current as of January 01, 2025. The same subsection provides that "No such unrecorded instrument or document shall be valid against any person with any kind of rights in or to such real property who first records and those holding rights under such person, except between the parties thereto and against those having notice thereof prior to acquisition of such rights", and then characterises itself: "This is a race-notice recording statute." That sentence was deliberately checked against both mirrors before being treated as statutory text rather than an editor's gloss. It appears inline in subsection (1) in both copies, and two publishers with separate editorial pipelines would not insert the same characterisation at the same point. Instruments conveying real property to the state or a political subdivision are recorded under section 38-35-109.5 instead.

records

A chain of title is searched through the grantor and grantee indices

verified

C.R.S. § 30-10-408

Every Colorado county clerk and recorder keeps a grantor index and a grantee index, and a chain of title is traced by working name by name back through them.

Every county clerk and recorder shall keep a grantor index and a grantee index in the clerk and recorder's office.
read from Public.Law, Colorado Revised Statutes, current through Fall 2025

Checked July 29, 2026. Section read at colorado.public.law, current through Fall 2025. It sets out seven columns for each index: time of reception, names of grantors, names of grantees, type of document, volume and page where recorded, remarks, and description of tract. Subsection (1)(b) requires the clerk and recorder to make correct entries in the grantor index of every document filed or recorded concerning or affecting real estate, entering the names of the grantors in alphabetical order, and subsection (2) does the same for the grantee index. This establishes the index a title search actually runs on. It does not establish how any individual county exposes that index online, which differs county by county and is not published here.

What an operator owes the surface owner

This is the section where Colorado is most often described wrongly, and the error is always in the same direction: treating the mineral estate as simply dominant and stopping there.

surface-use

An operator must accommodate the surface owner

verified

C.R.S. § 34-60-127(1)(a)

Colorado's accommodation statute requires an operator to conduct oil and gas operations in a way that minimizes intrusion on and damage to the surface, using alternatives that are technologically sound, economically practicable and reasonably available.

An operator shall conduct oil and gas operations in a manner that accommodates the surface owner by minimizing intrusion upon and damage to the surface of the land.
read from Public.Law, Colorado Revised Statutes, current through Fall 2025

Checked July 25, 2026. Full text read at colorado.public.law and corroborated at codes.findlaw.com, which states it is current as of January 1, 2025. The section also gives the surface owner a cause of action for a failure to meet the standard, and once the surface owner shows material interference the operator bears the burden of proving it met the standard. It contains no good-faith-negotiation requirement, no notice requirement and no bond provision; those are elsewhere.

surface-use

Both estates are mutually dominant and mutually servient

verified

Gerrity Oil & Gas Corp. v. Magness, No. 96SC215 (Colo. Sept. 15, 1997) (en banc)

Colorado's Supreme Court acknowledges the old label of a dominant mineral estate and then qualifies it: in a practical sense each estate is burdened by the rights of the other, so a flat statement that the mineral estate is dominant in Colorado overstates the law.

in a practical sense, both estates are mutually dominant and mutually servient because each is burdened with the rights of the other.
read from FindLaw Caselaw

Checked July 25, 2026. Full opinion read at caselaw.findlaw.com. The opinion first notes that "we have referred to the mineral estate as the dominant estate and the surface estate as the servient estate" and immediately gives the qualification quoted above, which is the controlling gloss. The Pacific Reporter citation reported elsewhere as 946 P.2d 913 was seen only in search-result titles and is deliberately omitted here.

surface-use

Use beyond what is reasonable and necessary is a trespass

verified

Gerrity Oil & Gas Corp. v. Magness, No. 96SC215 (Colo. Sept. 15, 1997) (en banc)

An operator's conduct on the surface is a trespass unless it is reasonable and necessary to develop the mineral interest, and the surface owner's initial burden is to show the conduct materially interfered with surface uses.

unless the conduct of an operator ... is reasonable and necessary to the development of the mineral interest, the conduct is a trespass.
read from FindLaw Caselaw

Checked July 25, 2026. Read in the same fetched opinion. The court also states that "the surface owner's initial burden is to present evidence that the operator's conduct materially interfered with surface uses", and that due regard "requires mineral rights holders to accommodate surface owners to the fullest extent possible consistent with their right to develop the mineral estate". A related point about expert testimony on the standard of care was only partially confirmed and is not quoted.

surface-use

No surface use agreement means the operator posts a bond

verified

Colorado Energy and Carbon Management Commission, 700 Series rules

When a surface owner is not party to a lease or surface use agreement, the operator must post financial assurance with the commission before bringing heavy equipment onto that owner's land: $4,000 per well on non-irrigated land, $10,000 per well on irrigated land, or a $100,000 statewide blanket.

if a Surface Owner is not a party to a lease, Surface Use Agreement, or other relevant agreement with an Operator, the Operator will provide Financial Assurance to the Commission prior to commencing any operations with heavy equipment on that Surface Owner's property.

Checked July 25, 2026. Read in the commission's own 700 Series rules PDF, marked as of April 30, 2022. The bond is released when a surface use agreement is entered. A surface owner claims against it through a hearing and bears the burden of proving unreasonable crop or land damage, and the award is not capped at the bond amount.

Pooling

pooling

A pooling order cannot hand over a nonconsenting owner's surface

verified

Colorado General Assembly, SB 19-181 as signed

Since 2019, every Colorado pooling order must prohibit the operator from using the surface owned by a nonconsenting owner without that owner's permission.

PROHIBIT THE OPERATOR FROM USING THE SURFACE OWNED BY A NONCONSENTING OWNER WITHOUT PERMISSION FROM THE NONCONSENTING OWNER.

Checked July 25, 2026. The signed act was read page by page, 20 sections over 29 pages, approved April 16, 2019. The capitalisation is the act's own, marking new statutory language. The same reading confirmed that the act did not touch § 34-60-127: that section appears nowhere in it.

Adverse possession and non use

The second rule below is published at partial confidence. The opinion that settles its affirmative half could not be reached on any source this site is allowed to cite, so the claim is not made at full strength and the caveat says exactly what is missing. That is the intended behaviour, not a gap we are hiding.

adverse-possession

Possessing the surface is not possessing the minerals

verified

Kriss v. Mineral Rights, Inc., 911 P.2d 711, 714 (Colo. App. 1996), quoted in Beaver Creek Ranch v. Gordman Leverich LLLP, No. 08CA1333 (Colo. App. May 28, 2009)

Once the mineral estate has been severed, possession of the surface is no longer possession of the minerals, so occupying the land does not run adverse possession against a severed mineral owner.

Possession of the surface estate constitutes possession of the mineral estate if the mineral estate has not been severed from the surface estate.
read from FindLaw Caselaw

Checked July 25, 2026. The sentence above is Kriss v. Mineral Rights, Inc., 911 P.2d 711, 714 (Colo. App. 1996), quoted verbatim inside Beaver Creek Ranch v. Gordman Leverich LLLP, which was fetched and read in full. Kriss itself was not reachable.

adverse-possession

Not using a mineral interest does not lose it

partial

Beaver Creek Ranch v. Gordman Leverich LLLP, No. 08CA1333 (Colo. App. May 28, 2009), quoting Kriss v. Mineral Rights, Inc., 911 P.2d 711 (Colo. App. 1996)read from FindLaw Caselaw

Non-use alone does not extinguish a severed Colorado mineral interest: losing one takes adverse possession of the minerals themselves, a conveyance, or a tax sale.

What is not confirmedThe affirmative half of the rule, that an adverse claimant must take actual possession of the minerals rather than the surface, appears only in summaries of Kriss v. Mineral Rights, Inc. The opinion itself could not be fetched, so it is not quoted here and the stronger statement is not published. This is the weakest link in the Colorado set.

Checked July 25, 2026. What is established: no Colorado statute lapses a mineral interest for non-use, and the severance point in Kriss was read verbatim inside a fetched opinion. What is not: any fetched holding that mere non-use cannot divest an owner.

Severance tax

Colorado taxes the gross income from oil and gas severed in the state on a four step bracket running from 2 percent to 5 percent, exempts stripper wells entirely, and allows a credit for local ad valorem taxes that the legislature is stepping down on a schedule written into the statute.

Colorado oil and gas severance tax, from C.R.S. § 39-29-105, read July 29, 2026, current through Fall 2025.
BracketRateNotes Gross income under $25,0002% Gross income $25,000 and under $100,0003% Gross income $100,000 and under $300,0004% Gross income $300,000 and over5% Stripper wellsExemptOil from a well producing 15 barrels per day or less, and gas from a well producing 90,000 cubic feet per day or less, averaged over all producing days in the taxable year. No ad valorem credit is allowed on exempt production. Ad valorem credit, taxable year 2026C = 0.65625 x GI x MLGI is the gross income attributable to the well for the taxable year and ML is the total of all mill levies fixed for property at the well's location. This replaced the flat credit: 87.5 percent applied to taxable years from 2000 through 2023, 75 percent to 2024 and 2025, and a formula of 0.7656 x GI x ML applies from 2027.

The credit for local ad valorem taxes is the part worth checking against the year you are actually filing for. It was a flat 87.5 percent for a quarter of a century, which is the figure most published guidance still repeats, and it is no longer the rule.

The regulator, and what it publishes

The state agency is the Colorado Energy and Carbon Management Commission, ECMC. It publishes the following, and all of it is free to search:

  • COGIS, the Colorado Oil and Gas Information System, with inquiries by facility, sample site, production, levy, inspection and incident, operator name and address and financial assurance, local government, reclamation inspection status by operator, and chemical disclosure
  • An imaged document search covering well files
  • Production by county
  • A permit search
  • An orders search, plus hearings and enforcement records
  • Rules, policies, forms and operator guidance
  • An online interactive GIS map
  • A public complaints search
  • Area reports, staff reports and technical reports

Checked July 29, 2026. Read from the commission's own site. It was renamed from the Colorado Oil and Gas Conservation Commission, so older documents and older search results still carry the previous name, and its records moved to a new site during 2026.

What has changed, with dates

Each entry is the date the change took effect, not the date we noticed it.

  • January 1, 2024. The oil and gas ad valorem tax credit dropped from 87.5 percent of ad valorem taxes assessed or paid to 75 percent, for taxable years beginning on or after January 1, 2024 and before January 1, 2026. C.R.S. § 39-29-105(2)(b)(II)
  • January 1, 2026. The flat percentage ad valorem credit ended. For taxable years beginning on or after January 1, 2026 and before January 1, 2027 the credit is calculated per well by the formula C = 0.65625 x GI x ML, where GI is gross income attributable to the well and ML is the total of all mill levies for property at the well's location. C.R.S. § 39-29-105(2)(c)
  • January 1, 2027. The per well ad valorem credit formula changes again, to C = 0.7656 x GI x ML, for taxable years beginning on or after January 1, 2027. C.R.S. § 39-29-105(2)(d)

What this page does not answer yet

Every page here says what it does not answer yet. A reference that never names its own gaps is one you cannot check.

  • How any individual county exposes its grantor and grantee indices. The statute establishes the indices every Colorado county clerk and recorder must keep, but search tools, fees and how far back the images go differ by county, and no county's own system was read for this page.
  • Whether the Department of Revenue's severance tax forms and guidance for taxable year 2026 implement the new per well ad valorem credit formula. The statute was read; the department's current year forms were not.
  • How the ad valorem credit is actually claimed on a return, and how it interacts with the local property tax a mineral owner already pays.
  • Unclaimed mineral proceeds. Royalties can escheat under Colorado's unclaimed property act, which is a different question from lapse of the mineral interest itself, and neither has been read here.
  • Whether an operator owes a surface owner notice or consultation before entering, and under which current rule number. The former rules 305 and 306 were renumbered in 2021. The commission's rules index was checked on 2026-07-29 and did not expose a linkable series document, so the current number is still unestablished.
  • The effective date of the 2007 accommodation statute. The session law was located; the effective date detail came from a snippet and is not published.
  • The Pacific Reporter citation for Gerrity Oil & Gas Corp. v. Magness, reported elsewhere as 946 P.2d 913. The full opinion was fetched again on 2026-07-29 and that citation does not appear anywhere in it, so it is still not published.
  • The affirmative half of the adverse possession rule, that a claimant must take actual possession of the minerals themselves. Kriss v. Mineral Rights, Inc. was searched again on 2026-07-29 across every allowlisted host and is still not reachable on one, so that rule stays partial.

Questions people actually ask

Does Colorado have a dormant mineral act?

No. Colorado has no dormant mineral interest statute. Title 38, Article 42 was read section by section and is about oil, gas and mining leases rather than severed mineral interests, and none of its six sections is a dormancy or lapse provision. The nearest analogue applies to leases rather than to mineral interests: a recorded lease stops operating as notice unless an extension affidavit is recorded within six months after the primary term. So a severed Colorado mineral interest does not expire because nobody used it.

Is the mineral estate dominant in Colorado?

Only with a qualification that matters. The Colorado Supreme Court acknowledges that it has referred to the mineral estate as dominant and the surface estate as servient, and then says that in a practical sense both estates are mutually dominant and mutually servient because each is burdened with the rights of the other. On top of that, the accommodation statute requires an operator to conduct operations in a way that minimises intrusion on and damage to the surface, using alternatives that are technologically sound, economically practicable and reasonably available. A flat statement that the mineral estate is dominant in Colorado overstates the law.

Where do I look up who owns the minerals under a Colorado property?

Start at the county clerk and recorder for the county where the land sits, because that is where instruments affecting title to real property are recorded, and work the grantor and grantee indices that every Colorado county clerk and recorder is required to keep. Colorado is a race notice state, so an unrecorded instrument does not beat someone who records first without notice of it. What a county index will not tell you is whether the United States reserved the minerals in the original patent, which is a federal record rather than a county one.

What is the Colorado severance tax on oil and gas?

Colorado taxes the gross income from oil and gas severed in the state on a four step bracket, from 2 percent on gross income under twenty five thousand dollars up to 5 percent on gross income of three hundred thousand dollars and over. Stripper wells are exempt: oil wells producing 15 barrels per day or less, and gas wells producing 90,000 cubic feet per day or less, averaged across producing days in the taxable year. A credit for local ad valorem taxes also applies, and it is on a declining schedule written into the statute rather than the flat 87.5 percent that older guidance quotes.

Does a Colorado title commitment have to tell me the minerals were severed?

Yes. Colorado requires a title insurance commitment to state that a mineral estate has been severed, leased or otherwise conveyed from the surface estate, and to warn that the mineral estate may include the right to enter and use the property without the surface owner's permission. That statutory warning is the single most common way a Colorado buyer first learns that the minerals under the property are not included in the purchase.
