A public record of who owns what is under the ground

Oregon mineral rights

Aug 2 2026

The short answer

Oregon has a dormant mineral act, and the thing to understand about it is not the thirty-year clock but the shortness of the list of things that stop it. Under ORS 517.180 the owner of the land can extinguish your mineral interest by publishing notice and recording an affidavit, unless one of exactly two things is true: you recorded a statement of claim in the last thirty years, or you acquired the interest in the last thirty years. Producing the minerals is not on the list. Granting a lease is not on the list. Paying tax on the interest is not on the list.

The document that proves any of this happened does not go in the deed book. It goes in the Mineral and Mining Record, a separate county record named after minerals, and a title search that stops at the deeds has not looked in the right place.

Can I lose my Oregon mineral rights, and what stops it?

Yes, and what stops it is recording, not using. ORS 517.180(1) lets an owner of land in which another person holds a mineral interest extinguish that interest by publishing notice and submitting an affidavit of publication for recording, "unless: (a) Within the last 30 years, the holder of the mineral interest has submitted a statement of claim for recording ...; or (b) The holder of the mineral interest acquired the mineral interest within the previous 30 years." Read the list twice, because what is absent from it is the whole point. Every comparable statute this site has read names uses that save an interest: Ohio, North Dakota, Michigan, Indiana, Kansas and Washington all do, and in Kansas and Washington paying the tax on the interest counts. Oregon names two record events and no uses at all. On the face of that text an Oregon owner who has been producing oil for forty years, who acquired the interest before that, and who never recorded a statement of claim, has nothing on file that stops the procedure. This site has not read a single Oregon decision, and a court asked whether forty years of production defeats a statute headed "Extinguishing Dormant Mineral Interest" may well not reach the answer the text alone suggests. What the text says and what a judge would hold are different things, and only the first of them has been checked here. If you hold an Oregon mineral interest and nothing is on record for you, the cheap and obvious move is a statement of claim under subsection (3), which needs only the holder's name and address as shown in the instrument that created the original interest and the name and address of the current holder. It restarts a thirty-year clock and it costs a recording fee.

Whether an interest can be lost by not using it

Four rules here rather than the usual one or two, because Oregon carries two statutory routes by which a mineral interest moves without its owner agreeing, and they sit in two separate acts a century apart. Illinois is the other state on this record with two, and both of its routes live inside a single statute. Read the policy section first: it tells you what the Oregon legislature thought it was doing.

The dormant mineral act says its purpose is to increase the state's tax base

ORS s. 517.170, Policy

ORS chapter 517 carries a heading block titled EXTINGUISHING DORMANT MINERAL INTEREST, and the first section under it is a policy section. It declares that it is in the interest of the State of Oregon to provide a mechanism for the removal of dormant encumbrances on property which prevent a landowner from using or developing that property in a manner which contributes to the economy and increases the state's tax base. That is the whole section. It was enacted by 1983 c.421 section 1, the same chapter that enacted the extinguishment procedure in the next section.

Checked August 2, 2026. Read at ORS 517.170 on 2026-08-02. Dormant mineral acts are ordinarily silent about why they exist, and where they are not silent they usually say something about development or about owners nobody can find. Two other statutes on this record state their own purpose and neither says this. Pennsylvania's Dormant Oil and Gas Act gives its purpose as facilitating development by reducing the problems caused by fragmented and unknown or unlocatable ownership, and protecting the interests of unknown or unlocatable owners. Wisconsin's metalliferous minerals tax says it is to compensate the state and municipalities for the loss of valuable, irreplaceable minerals. Oregon's names the tax base, which is a statement about the fisc rather than about anybody's title, and it is worth knowing that the legislature said so when reading what the operative section does and does not protect. WHAT IS NOT READ: the 1983 legislative history, and any Oregon decision citing this section.

Thirty years, and the only two things that stop it are a recorded claim and a recent acquisition

ORS s. 517.180, Procedure for extinguishing dormant mineral interest

An owner of land in which another person holds a mineral interest may extinguish the holder's interest by publishing notice and submitting an affidavit of publication for recording, unless one of two things is true: within the last thirty years the holder has submitted a statement of claim for recording, or the holder acquired the mineral interest within the previous thirty years. That is the entire list of exceptions. Producing the minerals is not on it. Granting a lease is not on it. Paying the tax on the interest is not on it. Mineral interest is defined to include any interest created by an instrument transferring, by grant, assignment, reservation or otherwise, an interest of any kind in coal, oil, gas or other minerals and geothermal resources, excluding interests vested in the United States, the State of Oregon or a political subdivision, and excluding sand and gravel; so it reaches leases and royalties as well as the fee mineral estate. Owner of land is defined as a vested fee simple owner or a contract purchaser, so a tenant cannot start it. And the section may not be waived at any time.

An owner of land in which another person holds a mineral interest, may extinguish the holder's interest by publishing notice and submitting an affidavit of publication for recording as described in subsections (4) to (9) of this section, unless: (a) Within the last 30 years, the holder of the mineral interest has submitted a statement of claim for recording in the manner set out in subsection (3) of this section; or (b) The holder of the mineral interest acquired the mineral interest within the previous 30 years.

Checked August 2, 2026. Read at ORS 517.180 on 2026-08-02, the section in full. Three things separate it from every other extinguishment statute on this record. THE PERIOD: thirty years. Every other one read here runs twenty, except Nebraska's twenty-three and Louisiana's ten-year prescription of nonuse; the thirty-year figures in Florida, Oklahoma and North Carolina's Avery County are marketable-title roots, which is a different device. THE SAVING EVENTS: two, and neither is use. Ohio, North Dakota, Washington, Michigan, Indiana and Kansas all list qualifying uses, and paying the tax counts in Kansas and Washington. On the face of this text an Oregon owner who has been producing oil for forty years, and who acquired the interest more than thirty years ago, has nothing recorded that stops the procedure. THE WAIVER BAR: subsection (10) says the provisions may not be waived AT ANY TIME. Washington's and North Dakota's non-waiver clauses both stop at the expiry of the twenty-year period; Oregon's has no expiry in it. WHAT IS NOT READ, and it matters here more than anywhere else on this page: no Oregon decision. A court asked whether forty years of production defeats a statute headed Extinguishing Dormant Mineral Interest might not reach the answer the text alone suggests, and nothing was fetched either way. Nor was anything read establishing that the section has ever been used.

Three weeks of newspaper notice, a mailing if you can be found, and sixty days to answer

verified

ORS s. 517.180, Procedure for extinguishing dormant mineral interest

To extinguish the interest and acquire ownership of it, the landowner must publish notice of the lapse at least once each week for three consecutive weeks in a newspaper of general circulation in the county where the lands are. If the holder's address is known or can be determined by due diligence, the notice must also be mailed to the holder before the first publication. The notice must give the holder's name as shown of record, a reference to the instrument creating the original interest including where it is recorded, a description of the lands, the name and address of the person giving notice, the date of first publication, and a statement that the holder must submit a statement of claim to the county clerk within sixty days after the last publication or the interest may be extinguished. Within fifteen days after the last publication the landowner files a copy of the notice and an affidavit of publication with the county clerk. That affidavit must state either that a copy was mailed and the address it went to, or, if none was mailed, give a detailed description including dates of the efforts made to find the address with due diligence. The interest is then extinguished and becomes the property of the landowner unless the holder submits a statement of claim within the sixty days.

If the owner of the land affected by the mineral interest gives notice as required in subsection (4) of this section and submits a copy of the notice and the affidavit of publication for recording as required by subsection (6) of this section, the mineral interest of the holder shall be extinguished and become the property of the owner of the lands, unless the holder of the mineral interest submits a statement of claim to the county clerk within 60 days after the date of the last publication of the notice.

Checked August 2, 2026. Read at ORS 517.180(3) to (9) on 2026-08-02. North Dakota is the pair for this, not the contrast: a North Dakota surface owner also publishes once a week for three weeks in the official county newspaper and also mails a copy where the address is of record or can be determined on reasonable inquiry. The probe that put Oregon on this record said North Dakota used publication as a fallback, which the North Dakota page here already contradicted; the fallback state is Washington, where service leads and publication is available only where the owner is unknown to the county treasurer and cannot be found after due diligence. What Oregon adds is the ORDER of the mailing. It goes out BEFORE the first publication, where North Dakota's goes within ten days AFTER the last one, which means an Oregon owner who is findable hears about it at the start of the three weeks rather than at the end. The statement of claim itself, under subsection (3), is short: it must give the holder's name and address as shown in the instrument that created the original interest, and the name and address of the current holder. WHAT IS NOT READ: what due diligence means here, and whether any Oregon court has measured it.

Miss your share of the assessment work on a mine and the county clerk deeds your interest away

verified

ORS s. 517.300, Effect of certificate

This is separate from the dormant mineral act and it reaches a narrower thing: quartz or placer mines owned by more than one person, which is the mining claim world rather than severed oil and gas. Any person owning a legal or equitable interest may perform the annual assessment work. If a co-owner fails to contribute their proportion, the performing co-owner may give notice at the end of the assessment year stating the work done, the dates, and the amount due, requiring payment within ninety days. Notice is served personally by the sheriff, or, if the delinquent co-owner cannot be found within the state, by publication once a week for ninety days in the weekly newspaper published nearest the mine. If the ninety days pass unpaid, title to the delinquent co-owner's interest is immediately vested in the co-owners who did the work. They file affidavits of nonpayment and the county clerk issues a certificate which is equivalent to a deed from the delinquent co-owner, recorded and indexed in the Mineral and Mining Record with the same force and effect as a deed and giving like constructive notice. No court is involved at any point. The delinquent owner's one defence is to file an affidavit of payment with the clerk before the certificate issues, which stops the clerk and leaves the parties to a suit to quiet title.

A certificate issued as provided in ORS 517.280 shall be equivalent to a deed from a delinquent co-owner of all the interest of the delinquent co-owner in and to all mines described in the notice, and shall convey the interest of the delinquent co-owner in the premises to the co-owner or co-owners who performed or caused to be performed the assessment work.

Checked August 2, 2026. Read at ORS 517.230 to 517.330 on 2026-08-02, the whole run. A county clerk issuing an instrument that operates as a deed, on one party's affidavit and with no judicial step, is not on this record anywhere else. Read it beside the dormant mineral act on the same page and Oregon carries two statutory routes by which a mineral interest moves without its owner agreeing, in two separate acts a century apart. Illinois is the other state here with two, and both of Illinois's sit inside one statute, the Severed Mineral Interest Act, which supplies a court trust that conveys to the surface owner after seven years and a statutory adverse possession proceeding at section 11. The distinction between two mechanisms in one act and two acts is not worth ranking, and no ranking is made here. SCOPE, and it is the thing to be careful about: assessment work is a mining claim concept and ORS 517.230 frames the sections as applying whenever quartz or placer mines are owned by one or more persons or owned in common. Nothing was read extending this to a severed oil and gas interest and this page does not extend it. The ninety-day publication is worth noticing on its own terms. Every other publication requirement read for this record runs three weeks: Oregon's own dormant mineral act, North Dakota's, Washington's fallback, Illinois's, Hawaii's mining lease notice. This one runs once a week for ninety days after the first publication, and the ninety-day payment window runs from the last of them. WHAT IS NOT READ: whether these sections are used, and what a modern Oregon court would do with a certificate issued under them.

The page on whether mineral rights expire sets every state on this record beside each other, and Oregon and North Dakota turn out to be the closest pair on it.

Who owns what the State kept, and how to make it give a reservation back

Oregon does not write a mineral reservation into every conveyance of state land the way Alaska, Washington and Hawaii do, so whether the State kept the minerals under a particular parcel is a question about the deed. What Oregon does have, and nothing else here has in this form, is a statutory route back out of a reservation for small urban and residential lots.

On a small residential or urban lot the State must release its mineral reservation, in sixty days, for a hundred and fifty dollars

ORS s. 273.787, Release and transfer of mineral or geothermal resource rights

Low-potential resource real property means real property located inside an urban growth boundary, or within an area zoned for residential use on a lot or parcel that is three acres or smaller. For such property, the Department of State Lands may not reserve mineral and geothermal resource rights in land the state sells or exchanges, unless it determines that a significant mineral or geothermal resource exists there. And where rights were reserved by the state before June 4, 2013, the owner, meaning the record holder of fee title or the contract purchaser, may apply at any time for their release and transfer. On that application the department shall release and transfer the reserved rights to the owner within sixty days of receiving the completed application, unless it determines a significant resource exists. The department may not require the owner to obtain an appraisal, and may not require the owner to pay for one conducted at the department's own request. The fee to process the application may not exceed one hundred and fifty dollars.

Upon application by the owner under this subsection, the department shall release and transfer to the owner the reserved rights to mineral and geothermal resources in low-potential resource real property within 60 days after the department receives the completed application, unless the department determines that a significant mineral or geothermal resource exists in the low-potential resource real property.

Checked August 2, 2026. Read at ORS 273.787 on 2026-08-02. [2003 c.676 s.3; 2013 c.256 s.2], and the 2013 act is what turned a power into a duty and put the clock on it. Two other states on this record let a state mineral reservation be released and neither works like this. Florida's Fla. Stat. 270.11 lets the reserving body sell or release the reserved interest on the owner's own application with a statement of reasons justifying it, which is discretionary. Hawaii's HRS 182-2(a) lets the board release, cancel or waive the reservation whenever it deems a land use other than mining of greater benefit to the State, which is also discretionary. Oregon's says SHALL, fixes sixty days, forbids an appraisal requirement, and caps the fee. It is also the only one on this record that draws its eligibility line by zoning and lot size rather than by the merits of the particular parcel. Note what the release is NOT: it is confined to low-potential resource real property, so it does nothing for rural acreage, and the department keeps an escape in the significant-resource finding, which nothing read defines. WHAT IS NOT READ: the department's rules under subsection (7), the application form, how many releases have been made, and what significant means.

ORS s. 273.780, Retention of mineral and geothermal resource rights by state

Mineral and geothermal resource rights in real property owned by any state agency, and mineral and geothermal resource rights retained as an interest in lands previously sold, granted or otherwise conveyed by the state or any agency of it, are property of the State of Oregon. Proceeds from them accrue to the Common School Fund, and the State Land Board is the state agency acting in any transaction respecting them. Those rights are subject to exploration permit or lease by the Department of State Lands. And they are retained by the state in the absence of a finding by the State Land Board, on adequate facts presented to it, that their sale or exchange is for the purpose of obtaining the greatest benefit for the people of this state consistent with the conservation of lands under its jurisdiction. Mineral for these sections is defined widely, running from oil, gas, sulfur and coal through gold, silver, copper, lead, cinnabar, iron and manganese to any other solid, liquid or gaseous material excavated or otherwise developed for commercial, industrial or construction use from natural deposits, and expressly including mineral waters of all kinds. Separately, the Department of State Lands must establish and maintain a registry of the mineral and geothermal resource rights placed under the State Land Board's jurisdiction.

Mineral and geothermal resource rights in real property owned by any state agency and mineral and geothermal resource rights retained as an interest in lands previously sold, granted or otherwise conveyed by the state or any agency thereof are property of the State of Oregon.

Checked August 2, 2026. Read at ORS 273.775, 273.780, 273.785 and 273.790 on 2026-08-02. The phrase to notice is RETAINED AS AN INTEREST IN LANDS PREVIOUSLY SOLD, GRANTED OR OTHERWISE CONVEYED, which is the sentence that reaches private land: if the state kept the minerals when it parted with the surface, whenever that was, the minerals are still the state's and the Common School Fund gets the proceeds. Unlike Alaska, Washington and Hawaii, nothing read here writes a reservation into every conveyance of state land automatically, so whether a particular Oregon parcel is subject to one is a question about the deed rather than about the statute; ORS 273.780(3) makes retention the default going forward, but that is a policy about future transactions, not a term implied into past ones. The exclusions in 273.785 are worth knowing because they are ordinary things: soil, clay, stone, sand and gravel that state agencies acquire or use for constructing or repairing roads or other state facilities are outside these sections, as are mineral or geothermal rights the State Fish and Wildlife Commission acquires under certain agreements. WHAT IS NOT READ: the registry itself under 273.790, whether it is published or searchable, and how a private owner queries it.

Geothermal follows the surface unless it was reserved or conveyed, and 250 degrees decides whether it is a mineral at all

verified

ORS s. 522.035, Ownership rights

Ownership rights to geothermal resources are in the owner of the surface property underlain by the resources, unless those rights have been otherwise reserved or conveyed, and nothing in the section divests the people or the state of any rights, title or interest they may have. Whether the chapter reaches a well at all is decided by temperature rather than by substance. The provisions on regulating production from a geothermal reservoir apply only to wells with a bottom hole temperature of at least two hundred and fifty degrees Fahrenheit, and the provisions on location and drilling do not apply to wells, other than prospect wells, where the fluids produced are of less than that temperature or where the fluids have been appropriated under the ground water statutes. If a well that was initially at least two hundred and fifty degrees falls below it, the State Geologist and the Water Resources Director, after consulting the well owner, determine which agency has regulatory responsibility for that specific well, and the determination is documented in writing and supersedes the general rule.

Ownership rights to geothermal resources shall be in the owner of the surface property underlain by the geothermal resources unless such rights have been otherwise reserved or conveyed.

Checked August 2, 2026. Read at ORS 522.035 and 522.025 on 2026-08-02. Hawaii is the only other state on this record whose statutes address who owns geothermal, and it goes the other way: HRS 182-1 makes all geothermal resources a mineral by definition and 182-2 reserves the minerals under state lands and reserved lands to the State. Oregon starts from the surface owner and lets the split be made by instrument. Note that ORS 273.775 pairs mineral and geothermal resource rights throughout for state lands, so on land the state kept, the two travel together. The temperature line is the thing to take away, because it decides which agency, which permit and which body of law: at or above two hundred and fifty degrees Fahrenheit at the bottom of the hole it is geothermal and DOGAMI has it, and below that it is ground water and the Water Resources Department has it. WHAT IS NOT READ: any Oregon decision on whether a general mineral reservation carries geothermal with it, which is a real and contested question elsewhere and which this record cannot answer for Oregon.

If somebody wants to mine under you

This is the section where Oregon's answer runs the opposite way from most of this record. Nothing read gives a surface owner damages, consultation or a veto; two sections make obstructing a mining operation a crime; and the word "landowner" in the reclamation statutes does not mean you.

ORS s. 517.128, Restricting access to open mining area or mining claim prohibited

Nothing read in Oregon's mineral resources title gives a surface owner a claim for damages against a mineral owner, a right to be consulted, a right to consent, or an accommodation standard. The surface owner appears in these chapters twice and both times as information on a permit application: an exploration permit application must give the name and address of the surface owner and mineral owner, and an operating permit application must give the name and address of the landowner, the owner of the surface estate, the operator and any parent corporations. What the statutes do provide runs the other way. A person may not attempt to restrict access to any open mining area or valid mining claim, or to harass or interfere in any way with a person engaged in lawful mining activities. A person commits the crime of mineral trespass, a Class C misdemeanour, by intentionally and without the permission of the claim holder entering a posted mining claim and disturbing or removing minerals, tampering with a flume, rocker box, bedrock sluice, sluice box, dredge, quartz mill or other mining equipment at a posted claim, or defacing a location stake, side post, corner post, landmark, monument or posted written notice within one. And a person commits the crime of interfering with a mining operation, also a Class C misdemeanour, by intentionally interfering with or stopping a lawful small scale mining operation.

A person may not attempt to restrict access to any open mining area or valid mining claim or to harass or interfere in any way with a person engaged in lawful mining activities.

Checked August 2, 2026. The negative was established on 2026-08-02 by enumeration with controls and not by any search. The instrument is the complete text of all four chapters of Title 43, Mineral Resources, fetched in four requests: ORS 516 at 53,867 characters, ORS 517 at 403,942, ORS 520 at 95,218 and ORS 522 at 160,798. Counted case-insensitively across all four, SURFACE DAMAGE returns 0, ACCOMMODAT 0, CONSENT OF THE SURFACE 0, CONSENT OF THE OWNER 0, REASONABLE USE 0 and WRITTEN CONSENT 0. SURFACE OWNER returns 2 and SURFACE ESTATE 1, all three in permit applications and inspected individually. DAMAGES returns 0 in 516, 517 and 520, and 2 in 522, both of them at ss. 522.080 and 522.155 making a well operator liable to any person or public agency that sustains damages from failure to comply with a permit condition protecting GROUND WATER; that is a water provision capable of reaching a surface owner and this record does not call it a surface damage act. The controls are what make the zeros mean something: PERMIT returns 397 in 517 alone and 503 across the four, RECLAMATION 195, NOTICE 180, LANDOWNER 25, LEASE 27 and ROYALTY 12. The positives were read at ORS 517.128, 517.130 and 517.133, all enacted by 1999 c.354, with an exemption at 517.135 for conduct required or authorised by law or judicial decree or performed by a public servant in the reasonable exercise of official powers. Those four sections carry an editorial note that they were enacted into law but were not added to or made a part of ORS chapter 517 or any series therein by legislative action, which affects where they sit in the code and not whether they are in force. THE LIMIT: this is a four-chapter enumeration over the title about minerals. It cannot exclude a surface protection sitting in the property or land use titles, and neither ORS 105 nor Oregon's land use statutes were enumerated for one.

In the reclamation statutes the word landowner means the owner of the mineral deposit, and it can be made to finish the reclamation

ORS s. 517.750, Definitions for ORS 517.702 to 517.989

The definitions for Oregon's mined land reclamation statutes define landowner to mean the person possessing fee title to the natural mineral deposit being surface mined or explored, and the owner of an equitable interest in land subject to a deed of trust. It does not mean the owner of the surface. That definition governs every use of the word across ORS 517.702 to 517.989, which is the whole reclamation and operating permit regime. It matters because those sections put real duties on the landowner: a landowner or operator may not allow or engage in surface mining on land not surface mined on July 1, 1972 without a valid operating permit, and where the landowner has given the security under ORS 517.810(3) and the operator is in default, the landowner shall be held responsible for complying with the operator's reclamation plan, with written notice from the department, thirty days to commence and a requirement to pursue it diligently, failing which the department claims the bond and may do the work itself and charge it.

"Landowner" means: (a) The person possessing fee title to the natural mineral deposit being surface mined or explored; and (b) The owner of an equitable interest in land that is subject to a deed of trust.

Checked August 2, 2026. Read at ORS 517.750(7), 517.790(1) and 517.860(4) on 2026-08-02. This is a terminology trap of exactly the kind that makes a reader draw the wrong conclusion from a correctly quoted statute, and it is Hawaii's problem inverted: there the statute uses an unfamiliar word, OCCUPIER, for the familiar person on top, and a reader notices they need to look it up. Here the statute uses the most familiar word there is for somebody else entirely, and a reader has no reason to check. Twenty-five occurrences of LANDOWNER in ORS 517 were inspected individually and none of them creates a right in the person who owns the surface. Be exact about 517.860(4), because overstating it would be its own error: it bites only where the landowner GAVE THE SECURITY under 517.810(3). A mineral owner who posted no bond is not made responsible for an operator's abandoned reclamation by that subsection. WHAT IS NOT READ: ORS 517.810(3) itself beyond its cross-reference, and whether the department has ever proceeded against a landowner under this route.

ORS s. 520.220, Integrating interests or tracts within spacing unit

The DOGAMI governing board establishes spacing units for a pool or field when necessary to prevent waste of oil or gas, to avoid the drilling of unnecessary wells or to protect correlative rights. Units are of uniform size and shape for the whole pool or field, subject to zoning it, and may not be smaller than the maximum area one well can efficiently drain. Where two or more separately owned tracts are within a spacing unit, or there are separately owned interests in it, the interested persons may integrate voluntarily. In the absence of voluntary integration the board, on the application of any interested person, shall make an order integrating all tracts or interests in the spacing unit for the development and operation of it and for the sharing of production from it, and each such order shall be upon terms and conditions that are just and reasonable. As part of the order establishing spacing units the board may prescribe the terms on which royalty interests are deemed integrated without a later order. An owner who finds that a well at the prescribed location would not produce in paying quantities, or that surface conditions would substantially add to the burden or hazard of drilling, may apply to move it, and the department must notify adjacent mineral owners, any of whom may request a hearing within twenty days.

In the absence of voluntary integration, the governing board of the State Department of Geology and Mineral Industries, upon the application of any interested person, shall make an order integrating all tracts or interests in the spacing unit for the development and operation thereof and for the sharing of production therefrom.

Checked August 2, 2026. Read at ORS 520.220 and 520.210 on 2026-08-02. What is absent is the whole finding. There is no risk charge, no non-consent penalty, no cost-free royalty fraction, no consent percentage, no acreage threshold and no election for an owner who will not join, only the words just and reasonable. Set that against the numbers elsewhere on this record: Florida carries a nonconsenting owner at three hundred per cent of costs, Washington at one hundred and fifty, Alabama guarantees three sixteenths free of every cost, North Dakota a cost-free royalty. Hawaii's s. 182-9.5 is the other provision here that fixes nothing, and the two differ in the way that matters to an owner: Hawaii's is discretionary, the board MAY order it, where Oregon's is mandatory on any interested person's application, the board SHALL. Note also that Oregon's spacing statute expressly bars spacing units for gas storage injection, withdrawal and monitoring wells and for underground disposal wells. WHAT IS NOT READ: DOGAMI's rules at OAR chapter 632, which is where any actual terms would live, and whether any spacing or integration order has ever been made in Oregon.

No Oregon opinion classifying the state was fetched, so no label is applied here, only the text. Set it against North Carolina, which is on this record as pure race: there the first to register wins and notice does not come into it at all.

records

The county index and no other record gives constructive notice, and a severed owner is covered even though they are never in possession

verified

ORS s. 93.710, Instruments or memoranda creating certain interests in realty

To give constructive notice of an interest in real property, a person must have documentation of the interest recorded in the indices maintained under ORS 205.130 in the county where the property is located, and that recordation, and no other record, constitutes constructive notice to any person of the existence of the interest, subject to a listed set of exceptions covering property tax, statutory liens, certain public improvement and utility chapters, local government charters, and a city's online governmental lien record. Alongside that, an instrument creating an oil, gas or other mineral interest or estate in real property, or a memorandum of it, may be indexed and recorded in the deed records of the county, and such recordation constitutes notice to third persons of the rights of the parties under the instrument irrespective of whether the party granted the interest or estate is in possession of the real property.

Such recordation, whether the instrument be recorded prior to or subsequent to May 29, 1963, constitutes notice to third persons of the rights of the parties under the instrument irrespective of whether the party granted such interest or estate is in possession of the real property.

Checked August 2, 2026. Read at ORS 93.643(1) and 93.710(1) on 2026-08-02. The second of those is aimed squarely at the thing that makes a severed mineral interest different from every other interest in land: its owner is never in possession, so any doctrine that runs notice off possession can never help them. The clause was put there by 1963 c.416 s.1 and it names oil, gas and other mineral interests expressly. The first is worth as much to a searcher and for a different reason: a statute saying in terms that the county index AND NO OTHER RECORD gives constructive notice tells you that a search which covers those indices is complete, subject only to the listed exceptions, and that a document lodged anywhere else is not charged against you. The exceptions are the qualification and they are real, including a city's electronic lien record, which is expressly made the controlling lien record to the exclusion of any informational recording in the county indices. WHAT IS NOT READ: the indices themselves, whether Oregon counties maintain a consolidated index or separate deed and mortgage books under ORS 93.610, and any Oregon decision on the reach of 93.643.

records

The proof that an interest was extinguished sits in the Mineral and Mining Record, not the deed book

verified

ORS s. 205.246, Instruments to be recorded; fees

Oregon county clerks keep a separate record called the Mineral and Mining Record. The statute listing the instruments a county clerk must record names it and names exactly which sections feed it: mineral and mining records required under ORS 517.030, 517.052, 517.160, 517.180, 517.210, 517.220, 517.280, 517.310 and 517.320. Read those nine back and the contents are lode claim location notices, placer claim location notices, millsite locations, the dormancy statement of claim together with the notice and affidavit of publication that extinguishes an interest, annual assessment work affidavits, the evidentiary effect of those affidavits, the certificate transferring a delinquent co-owner's interest, the recording and indexing of that certificate, and a judgment in a quiet title suit between co-owners. The clerk must also, when possible, indicate by marginal notation on the instrument that created the original mineral interest that a statement of claim or a notice and affidavit of publication has been recorded, and must cross-reference a statement of claim in the Mineral and Mining Record under both the current holder's name and the original holder's name.

Upon receipt, the clerk of the county shall record a statement of claim or a notice and affidavit of publication of notice in the Mineral and Mining Record. When possible, the clerk shall also indicate by marginal notation on the instrument creating the original mineral interest the recording of the statement of claim or notice and affidavit of publication of notice.

Checked August 2, 2026. Read at ORS 205.246(1)(s) and 517.180(9) on 2026-08-02, with ORS 205.130 for the clerk's general recording duties and the indices. The practical consequence is the reason this is a rule rather than a footnote: in Oregon the document that establishes whether a mineral interest was extinguished, or preserved, is not in the deed records, and a title search that reads the deed and mortgage books and stops has not looked in the right place. North Carolina's G.S. 1-42 book is the other named special book on this record and it holds something different, the yearly notices of intended use that stop adverse possession running across a severance. The marginal notation is the searcher's friend and the words WHEN POSSIBLE are the searcher's problem: it is not guaranteed, so a clean margin on the severing deed proves nothing. WHAT IS NOT READ: whether Oregon counties actually maintain the Mineral and Mining Record as a distinct index today or fold it into a consolidated index, how far back it runs, and how it is searched online in any particular county.

The page on finding who owns the minerals sets out how a search runs and where the offices differ from state to state. In Oregon there are three places rather than one: the county deed and mortgage indices, the county Mineral and Mining Record, and the Department of State Lands registry of what the State itself holds.

What the State taxes, and the words it makes them print

Oregon levies a privilege tax of six per cent of the gross value at the well on the production of oil and gas, at one rate, with no brackets, no marginal-well band and no stripper relief. The tax is measured by the value of the whole production, including what the statute calls what is commonly known as the royalty interest, so a royalty owner bears their share of it. The first three thousand dollars of gross sales value each calendar quarter from each well is exempt, which is a per-well and per-quarter allowance rather than a rate cut. Interests owned by the state, counties, cities, towns, school districts and other municipal corporations are exempt outright, and every taxpayer gets a credit against the tax for the ad valorem taxes imposed on the right to produce, on producing leases, on wellhead machinery, on the oil and gas produced and on any investment in that property, which means the property tax on the same production can eat the severance tax on it. What is collected, after refunds and the Department of Revenue's costs, is paid into the Common School Fund and continuously appropriated to the Department of State Lands, which is the same fund that receives the royalties on the State's own retained mineral rights under ORS 273.780.

Six per cent of gross value at the well, measured on the whole production including the royalty interest

verified

ORS s. 324.070, Imposition of tax; rate; basis of levy

A privilege tax of six per cent of the gross value at the well is levied upon the production of oil and gas within the State of Oregon, and the gross value at the well is reduced by the value of any part of it the ownership of which is exempt from taxation. The tax is measured by the value of the whole production, including what is commonly known as the royalty interest, so it reaches the royalty owner's share and not only the operator's. Gross value means the actual cash price prevailing for oil or gas of that kind, character and quality at the time it is produced, as determined by the Department of Revenue. An exemption is granted on the first three thousand dollars in gross sales value of the gross production each calendar quarter from each well, which is a per-well and per-quarter allowance rather than a rate reduction. Royalty or other interests in oil or gas owned by the state, counties, cities, towns, school districts or other municipal corporations or political subdivisions are exempt outright. And there is a credit against the tax for all ad valorem taxes imposed by state or local government on the property rights attached to or inherent in the right to produce oil and gas, on producing leases, on the machinery, appliances and equipment used in and around a producing well, on the oil and gas produced in the state, and on any investment in that property. The tax is paid quarterly, due on the forty-fifth day after the quarter.

A privilege tax of six percent of the gross value at the well is levied upon the production of oil and gas within the State of Oregon. ... The tax levied shall be measured by the value of the whole production, including what is commonly known as the royalty interest.

One rate for oil and for gas, with no brackets, no marginal-well band and no stripper relief, which makes it the plainest severance tax on this record to state and not the cheapest to bear. Two features are worth more than the rate. The subsection saying the tax is measured on the whole production INCLUDING the royalty interest is the statute doing openly what most severance taxes do by implication, and it is the answer to a royalty owner asking whether the tax is the operator's problem: it is not. And the ad valorem credit at 324.090(2) is wide enough that the property tax on the same production and the same equipment can consume the severance tax on it, which no other credit read on this record does. Definitions to keep: OIL means petroleum, crude oil, mineral oil and casinghead gas, and GAS means natural gas and casinghead gas, so casinghead gas falls in both; GROSS PRODUCTION is the total volume extracted including oil or gas extracted but not sold, and excludes anything reinjected for storage. WHAT IS NOT READ: whether any oil or gas is currently produced in Oregon, and what the tax actually raises.

ORS s. 324.510, Content of statement or settlement sheet

All statements or settlement sheets for oil or gas must have stamped or written on them the following words: Gross production tax deducted and paid, and payee accepts such deduction and authorizes payment to the State of Oregon. The provision sits in a short miscellaneous group at the end of the oil and gas tax chapter, alongside a duty on every person producing oil and gas in the state to furnish the Department of Revenue whatever information about production the department requires on its forms, with power to require suitable measuring devices; a quarterly reporting duty on every refinery operator processing oil or gas in the state; and a quarterly reporting duty on every person purchasing or storing oil, giving the location, identity, character and capacity of the storage receptacle. Reports are delinquent if not filed by the forty-fifth day after the quarter and the penalty is twenty-five dollars for each day of failure or refusal. After refunds and the Department of Revenue's administrative expenses, the net revenue is paid into the Common School Fund and continuously appropriated to the Department of State Lands.

A statute that dictates the exact words printed on a royalty check stub, and makes accepting the payment an authorisation of the deduction, is not on this record anywhere else. The nearest thing is North Carolina's G.S. 105-187.83, which does something different and puts the duty on the other side: it requires the owner of a royalty interest to KEEP a record of all money received and a copy of every settlement sheet showing the volume and the severance tax deducted, and to hand them to the Secretary of Revenue on request. The destination of the money is worth noticing beside ORS 273.780, which sends the royalties on the State's own retained mineral rights to the same Common School Fund: the tax on private production and the rent on public minerals run into the same account, administered by the Department of State Lands. No claim is made here about where other states send their severance tax, because their destinations were not checked. WHAT IS NOT READ: whether the stamped words have ever been litigated, and what a payee who strikes them out achieves.

The page on mineral rights taxes is about what you owe on royalty income rather than about state rates, and the valuation page is where every state's production rate on this record sits side by side.

Money nobody claimed

unclaimed

The unclaimed property act never uses the word mineral, so a suspended royalty falls to the three year catch-all

verified

ORS s. 98.342, Miscellaneous personal property held for another person

Oregon's unclaimed property act contains no mineral proceeds provision of any kind. There is no definition of mineral proceeds, no separate abandonment period for royalties, bonuses, shut-in payments or delay rentals, and no suspense-account rule for an operator holding money for an owner it cannot find. A suspended Oregon royalty therefore falls to the catch-all: all intangible personal property not otherwise covered by the act, including any income or increment on it and deducting any lawful charges, that is held or owing in the ordinary course of the holder's business and has remained unclaimed by the owner for more than three years after it became payable or distributable, is presumed abandoned. The same section adds that property is payable or distributable notwithstanding the owner's failure to make demand or to present any instrument or document required to receive payment, so never having asked does not stop the clock. Property becomes subject to the custody of the state where the apparent owner's last known address on the holder's records is in Oregon, or where the records do not show who is entitled and the last known address of the person entitled is in Oregon. The holder reports and delivers to the State Treasurer.

All intangible personal property, not otherwise covered by ORS 98.302 to 98.436 and 98.992, including any income or increment thereon and deducting any lawful charges, that is held or owing in the ordinary course of the holder's business and has remained unclaimed by the owner for more than three years after it became payable or distributable is presumed abandoned.

Checked August 2, 2026. The negative was established on 2026-08-02 by enumeration with controls and not by any search. The instrument is ORS chapter 98, Lost, Unclaimed or Abandoned Property; Vehicle Towing, 322,865 characters fetched in one request, which contains the Uniform Disposition of Unclaimed Property Act at ss. 98.302 to 98.436. Counted case-insensitively over the whole chapter: MINERAL 0, ROYALTY 0, OIL 0. GAS returns 1 and it is GAS MILEAGE, in the vehicle towing sections, which confirms the zeros rather than qualifying them. The controls are what make them mean something: DIVIDEND 4, SAFE DEPOSIT 3, WAGES 13, UTILITY 8, INSURANCE 28, ESCHEAT 38 and THREE YEARS 12. North Carolina, Texas, Colorado and North Dakota all carry a mineral proceeds provision on this record and Oregon has none, so the substance-specific rules those states have, and North Carolina's bar on a property finder taking a cut of the underlying minerals in particular, have no Oregon equivalent. On the administrator: STATE TREASURER appears 109 times in the chapter and DEPARTMENT OF STATE LANDS once, so the page says the Treasurer because the statute does; nothing was read about when or how the programme moved. THE LIMIT: this is a whole-chapter term count over the chapter containing the unclaimed property act. It cannot exclude a mineral proceeds provision sitting in some other chapter, and none was looked for outside ORS 98.

Whether somebody can take it by using it

adverse-possession

Ten years, plus an honest belief you owned it, proved by clear and convincing evidence

verified

ORS s. 105.620, Acquiring title by adverse possession

A person may acquire fee simple title to real property by adverse possession only if three things hold. The person and their predecessors in interest have maintained actual, open, notorious, exclusive, hostile and continuous possession for ten years. At the time the claimant or their predecessors first entered into possession, the person entering had the honest belief that they were the actual owner, and that belief continued throughout the vesting period, had an objective basis, and was reasonable in the particular circumstances. And the person proves each element by clear and convincing evidence. Hostile possession means possession under claim of right or with colour of title, colour of title meaning the possessor claims under a written conveyance or by operation of law from someone claiming under one. Absent additional supporting facts, the grazing of livestock is insufficient to satisfy the possession requirement. Person includes the state and its political subdivisions.

At the time the person claiming by adverse possession or the person's predecessors in interest, first entered into possession of the property, the person entering into possession had the honest belief that the person was the actual owner of the property and that belief: (A) By the person and the person's predecessor in interest, continued throughout the vesting period; (B) Had an objective basis; and (C) Was reasonable under the particular circumstances.

The honest belief requirement is a deliberate legislative narrowing and it cuts against the knowing trespasser, which is a policy choice a good many states have not made. Nothing in the section says anything about a severed mineral estate, and no Oregon decision was read, so this page states the elements and refuses to say how a court would apply them across a severance. North Carolina is the state on this record where that question has a statutory answer, G.S. 1-42, and the answer there is that neither side can possess against the other without recording a yearly notice of intended use. Oregon has no equivalent, so the ordinary doctrine is all there is: possession of the surface is not possession of the minerals once they are severed, which is a proposition of general property law that this record has not verified against any Oregon authority. WHAT IS NOT READ: ORS 12.050, the limitation on actions for the recovery of real property, and any Oregon case on adverse possession of minerals.

The regulator

One agency holds all of it. The State Department of Geology and Mineral Industries, DOGAMI, regulates hard-rock mining and reclamation under ORS 517, oil and gas conservation under ORS 520 and geothermal under ORS 522, through its Mineral Land Regulation and Reclamation programme at Albany. Its governing board is the body that establishes spacing units and orders integration. It holds the following:

  • An Oil and Gas Well Logs page and an Oil and Gas Historical Production page, which is the closest thing Oregon has to a public file on a particular well and the first place a mineral owner should look
  • Permits and Production Information pages separately for surface mining, for oil and gas and for geothermal, plus a Geothermal Log Viewer and a GTILO viewer
  • A Closed Permit Viewer map for surface mining, so an expired or surrendered permit can still be found
  • Notices of Intent for chemical process mining, and complete project document sets for the two named projects currently in the consolidated application process, Calico Resources USA at Grassy Mountain and Sumpter Development at Cracker Creek
  • Separate 2026 fee schedules for ORS 517 mineral exploration and surface mining, ORS 520 oil and gas, and ORS 522 geothermal
  • Its Regulations and Statutes page, the ENGAGe newsletter, and the DOGAMI Governing Board's own materials, which is where a spacing order or an integration order under ORS 520.210 and 520.220 would be made

Checked August 2, 2026. Read from the programme's own pages. The first entry is the one to act on: Oregon publishes oil and gas well logs and historical production separately, so a mineral owner who wants to know what was drilled under them has somewhere to look that is not a title search. What DOGAMI does not hold is the ownership record. That is the county clerk, and in Oregon part of it is a book of its own, which the records rules above deal with.

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.

  • Any Oregon court decision. Nothing was fetched from the courts at all, and the gap that matters most is whether producing the minerals defeats ORS 517.180 despite production not being one of the two listed saving events. The text says it does not. No court has been read saying either way, and this is the single largest unread thing about this state.
  • Whether ORS 517.180 has ever been used by anybody. The statute has been on the books since 1983 and nothing read establishes that a single Oregon mineral interest has been extinguished under it.
  • DOGAMI's administrative rules, OAR chapter 632. That is where the terms missing from ORS 520.220 would live, if they live anywhere, and where the exploration and operating permit conditions actually sit.
  • Whether Oregon has a marketable record title act. ORS 93 contains no occurrence of the word marketable and exactly one occurrence of mineral, at s. 93.710, but that is a single-chapter count and not the whole-of-code enumeration Arizona and Hawaii were given. No negative is published for Oregon on this point.
  • The registry of state mineral and geothermal resource rights required by ORS 273.790. Whether the Department of State Lands publishes it, how far back it runs, and how a private owner searches it were not established.
  • Whether Oregon counties still maintain the Mineral and Mining Record as a distinct index, how far back it goes, and how to search it in any particular county. The statute requires it; nothing was read about the practice.
  • Landman licensing in Oregon. Not looked for.
  • Property tax treatment of a severed Oregon mineral interest. ORS 308 was not fetched, so nothing is said about whether a severed interest is separately assessed or can be lost for its own arrears, which is a live route to losing an interest in several other states on this record.
  • Any Oregon decision on whether a general mineral reservation carries geothermal resources with it. ORS 522.035 starts ownership with the surface owner unless reserved or conveyed and says nothing about what words in an old deed are enough to have conveyed it.
  • ORS 274, Submersible and Submerged Lands, beyond fetching it, and ORS 273 beyond the mineral and geothermal sections and the leasing cross-references.
  • When and under what act Oregon moved its unclaimed property programme to the State Treasurer, and what the Department of State Lands still does with escheated property.
  • The Common School Fund itself. Both the severance tax under ORS 324.340 and the royalties on the State's retained mineral rights under ORS 273.780 run into it, and nothing was read about what it holds or what the Department of State Lands does with the money.

Questions people actually ask

Does Oregon have a dormant mineral act?

Yes. It sits in the mining chapter rather than the property chapter, under a heading block titled "Extinguishing Dormant Mineral Interest", and it is two sections long. ORS 517.170 is a policy section declaring that "It is in the interest of the State of Oregon to provide a mechanism for the removal of dormant encumbrances on property which prevent a landowner from using or developing that property in a manner which contributes to the economy and increases the state's tax base." ORS 517.180 is the machinery. Both were enacted by 1983 c.421. Dormant mineral acts are usually silent about why they exist. Two others on this record are not: Pennsylvania's Dormant Oil and Gas Act states its purpose as facilitating development by reducing the problems caused by fragmented and unknown or unlocatable ownership and protecting the interests of those owners, and Wisconsin's metalliferous minerals tax says it is to compensate the state and municipalities for the loss of valuable, irreplaceable minerals. Oregon's names the tax base, which is a statement about public revenue rather than about anybody's title, and it is worth having in mind when reading what the operative section does and does not protect.

Does producing the minerals protect an Oregon mineral interest?

Not on the face of the statute, and this is the most important thing on this page. ORS 517.180(1) lists two exceptions and only two: a statement of claim submitted for recording within the last thirty years, or acquisition of the interest within the previous thirty years. There is no clause about production, no clause about a lease, no clause about a well, no clause about paying the tax on the interest, and no general saving for any "use". Compare what the other extinguishment statutes on this record do. Ohio, North Dakota, Michigan, Indiana and Kansas each set out a list of qualifying events that reset the clock, and those lists routinely include production, active mining, a recorded lease, a recorded transfer and a separate tax payment. Nebraska's includes using the pore space. Oregon's has none of them. Two consequences follow if the text is taken at its word. An owner producing steadily but with nothing on record is exposed, and an owner who has done nothing at all but bought the interest twenty-nine years ago is not. That is an inversion of what most people assume a dormancy statute rewards. The honest limit has to be stated as loudly as the finding: no Oregon court decision has been read for this site, and the question of whether decades of open production defeats a statute about "dormant" interests is exactly the sort of question that gets litigated and answered by a judge rather than by a reader. Nothing was found establishing that ORS 517.180 has ever been used at all. What can be said without any decision is that recording a statement of claim is cheap, is expressly the thing the statute asks for, and removes the question.

How does an Oregon landowner actually extinguish a mineral interest?

By publishing, mailing, waiting and filing, in that order, and it is entirely out of court. The landowner, meaning a vested fee simple owner or a contract purchaser, publishes notice of the lapse at least once each week for three consecutive weeks in a newspaper of general circulation in the county where the lands are. If the mineral holder's address is known or can be determined by due diligence, a copy must also be mailed to the holder before the first publication. The notice has to give six things: the holder's name as shown of record, a reference to the instrument creating the original interest and where it is recorded, a description of the lands, the name and address of the person giving notice, the date of first publication, and a statement that the holder must submit a statement of claim to the county clerk within sixty days after the last publication or the interest may be extinguished. Within fifteen days after the last publication the landowner files the notice and an affidavit of publication with the county clerk, and that affidavit must state either that a copy was mailed and to what address, or, if none was, a detailed description including dates of the due-diligence efforts made to find one. The interest is then extinguished and becomes the landowner's property unless a statement of claim arrives inside the sixty days. North Dakota's procedure is the near twin of this: three weeks of publication in the official county newspaper plus a mailing where the address is of record or findable on reasonable inquiry. The one real difference is when the letter goes out. Oregon's is mailed before the first publication; North Dakota's is mailed within ten days after the last one. Washington is the state where the shapes genuinely diverge, because there personal service or registered mail leads and publication is available only where the owner is unknown to the county treasurer and cannot be found after due diligence.

Can an Oregon mineral interest be lost any other way?

Yes, and the second route is stranger than the first. ORS 517.230 to 517.330 deal with co-owned quartz or placer mines, which is the mining-claim world rather than severed oil and gas, and they work like this. Any co-owner may perform the annual assessment work. If another co-owner does not pay their share, the performing co-owner gives notice at the end of the assessment year setting out the work done, the dates and the amount due, and requiring payment within ninety days. That notice is served personally by the sheriff, or, if the delinquent co-owner cannot be found within the state, by publication once a week for ninety days in the weekly newspaper published nearest the mine. When the ninety days pass unpaid, title to the delinquent co-owner's interest "shall be immediately vested" in the co-owners who did the work. They file affidavits of nonpayment, and the county clerk issues a certificate which ORS 517.300 says "shall be equivalent to a deed from a delinquent co-owner", recorded and indexed in the Mineral and Mining Record with the same force as a deed and giving like constructive notice. There is no court anywhere in that sequence. A county clerk issuing an instrument that operates as a deed, on one party's affidavit, is not on this record anywhere else. The delinquent owner's single defence is timing: file an affidavit with the clerk saying the payment was made before the certificate issues, and the clerk must not issue it, leaving both sides to a suit to quiet title in which the court decides who actually did and paid for the work. Nothing read establishes that these sections are used today, and nothing was read about what a modern court would do with a certificate issued under them.

Can I make Oregon give back a mineral reservation on my land?

If your land is small and urban or small and residential, yes, and the statute says "shall". ORS 273.787 defines "low-potential resource real property" as real property located inside an urban growth boundary, or within an area zoned for residential use on a lot or parcel that is three acres or smaller. For such property two things follow. The Department of State Lands may not reserve mineral and geothermal resource rights when the state sells or exchanges it, unless the department determines that a significant resource exists there. And where rights were reserved before June 4, 2013, the owner, meaning the record holder of fee title or the contract purchaser, "may apply at any time" for their release, and on that application the department "shall release and transfer to the owner the reserved rights ... within 60 days after the department receives the completed application", unless it determines a significant resource exists. The department may not require an appraisal, may not make the owner pay for one it asks for itself, and may not charge more than $150 to process the application (ORS 273.787(5) and (6)). Two other states on this record let a state reservation be released and neither works like this: Florida's route under Fla. Stat. 270.11 is on the owner's application with a statement of reasons and is discretionary, and Hawaii's under HRS 182-2(a) is a board judgment that a non-mining use is of greater benefit. Oregon's is a duty with a clock and a price cap on it, and it draws its line by zoning and lot size rather than by the merits of the parcel. Note what it does not do. It is confined to low-potential resource real property, so rural acreage gets nothing from it, and the department keeps an escape in the "significant mineral or geothermal resource" finding, which nothing read defines. The department's rules under subsection (7), the application form, and how many releases have actually been granted were not read.

Does an Oregon surface owner get damages if somebody mines under them?

Nothing read gives them any, and the statutes that do exist run the other way. The negative was established by enumerating the complete text of all four chapters of Title 43, Mineral Resources, rather than by any search: ORS 516 at 53,867 characters, ORS 517 at 403,942, ORS 520 at 95,218 and ORS 522 at 160,798, all four fetched whole. Counted across them, "surface damage" returns zero, "accommodat" zero, "consent of the surface" zero, "consent of the owner" zero, "reasonable use" zero and "written consent" zero. "Surface owner" returns two and "surface estate" one, and all three were inspected individually: every one is a line on a permit application requiring the applicant to name the surface owner. "Damages" returns zero in three of the four chapters and twice in ORS 522, at sections 522.080 and 522.155, both making a well operator liable to anyone who sustains damages from failing to comply with a permit condition protecting ground water. That is a water provision that can happen to reach a surface owner; it is not a surface damage act and this page does not call it one. The controls are what make the zeros mean something rather than proving the search was broken: "permit" returns 503 across the four chapters, "reclamation" 195, "notice" 180, "landowner" 25, "lease" 27 and "royalty" 12. What Oregon does have is protection running to the miner. ORS 517.128 says a person may not attempt to restrict access to any open mining area or valid mining claim, or harass or interfere in any way with a person engaged in lawful mining activities. ORS 517.130 makes mineral trespass a Class C misdemeanour, and ORS 517.133 makes interfering with a mining operation a Class C misdemeanour. The limit is real and worth stating: this is an enumeration of the four chapters about minerals, and it cannot exclude a surface protection sitting somewhere in Oregon's property or land use statutes, which were not enumerated for one.

Who owns geothermal resources in Oregon?

The surface owner, unless the geothermal rights were reserved or conveyed away. ORS 522.035 says "Ownership rights to geothermal resources shall be in the owner of the surface property underlain by the geothermal resources unless such rights have been otherwise reserved or conveyed", with a saving that nothing in the section divests the people or the state of any rights they may have. Hawaii is the only other state on this record whose statutes address who owns geothermal, and it starts from the opposite end: HRS 182-1 makes all geothermal resources a mineral by definition and 182-2 reserves the minerals under state lands and reserved lands to the State. The second half of Oregon's answer is a jurisdictional line drawn by temperature rather than by substance. The chapter's provisions on regulating production from a geothermal reservoir apply only to wells with a bottom hole temperature of at least 250 degrees Fahrenheit, and its location and drilling provisions do not apply to wells other than prospect wells where the fluids are cooler than that or have been appropriated under the ground water statutes. If a well that began above 250 degrees falls below it, the State Geologist and the Water Resources Director determine between them, after consulting the well owner, which agency has that specific well, and the determination goes in writing and supersedes the general rule. So whether your hot water is a mineral resource or is ground water turns on a thermometer at the bottom of the hole. One thing this record cannot tell you: whether a general mineral reservation in an old Oregon deed carries the geothermal with it. That is a real and contested question and no Oregon decision was read on it.

Where are Oregon mineral rights recorded?

In the county, but in more than one place in it, and the extra place is the one that matters. Ordinary conveyances go in the county clerk's deed and mortgage records. ORS 93.643 then says something unusually useful to a searcher: to give constructive notice of an interest in real property a person must have it recorded in the indices maintained under ORS 205.130 in the county where the property is, and "such recordation, and no other record, constitutes constructive notice", subject to a listed set of exceptions covering property tax, statutory liens, several public improvement chapters, local government charters and a city's online lien record. And ORS 93.710 deals expressly with the problem that makes a severed mineral interest different from every other interest in land, which is that its owner is never in possession: an instrument creating an oil, gas or other mineral interest may be recorded in the deed records, and that recording is notice to third persons "irrespective of whether the party granted such interest or estate is in possession of the real property". The extra place is the Mineral and Mining Record. ORS 205.246(1)(s) requires the county clerk to record "Mineral and mining records required under ORS 517.030, 517.052, 517.160, 517.180, 517.210, 517.220, 517.280, 517.310 and 517.320". Read those nine back and it holds lode and placer claim location notices, millsite locations, the dormancy statement of claim together with the notice and affidavit of publication that extinguishes an interest, annual assessment affidavits, the certificate transferring a delinquent co-owner's interest and its indexing, and a quiet title judgment between co-owners. So in Oregon the document establishing whether a mineral interest was extinguished or preserved is not in the deed book at all. North Carolina's G.S. 1-42 book is the other named special book on this record and it holds something different. The clerk must also, "when possible", put a marginal notation on the instrument that created the original mineral interest, and "when possible" is the searcher's problem: a clean margin proves nothing. Third place, for a different question: ORS 273.790 requires the Department of State Lands to maintain a registry of the mineral and geothermal rights under the State Land Board's jurisdiction, which is where to ask whether the State kept them.

Does Oregon have a severance tax on oil and gas?

Yes, at six per cent of the gross value at the well, one rate for oil and for gas, with no brackets, no marginal-well band and no stripper relief. ORS 324.070(1) calls it a privilege tax and reduces the gross value at the well by the value of any part whose ownership is exempt from taxation. Subsection (2) then says the thing a royalty owner needs to see: the tax "shall be measured by the value of the whole production, including what is commonly known as the royalty interest". Most severance taxes reach the royalty by implication; Oregon's says so. There are three reliefs. ORS 324.080 exempts the first $3,000 in gross sales value of gross production each calendar quarter from each well, which is an allowance per well and per quarter rather than a rate cut. ORS 324.090(1) exempts royalty and other interests owned by the state, counties, cities, towns, school districts and other municipal corporations outright. And ORS 324.090(2) gives a credit against the tax for all ad valorem taxes imposed on the property rights attached to or inherent in the right to produce, on producing leases, on the machinery and equipment used in and around a producing well, on the oil and gas produced, and on any investment in that property. That credit is wide enough that the property tax on the same production can consume the severance tax on it. The tax is paid quarterly, due on the forty-fifth day after the quarter, with a possible thirty-day extension. Where the money goes is worth a line: after refunds and the Department of Revenue's costs, ORS 324.340 pays it into the Common School Fund, continuously appropriated to the Department of State Lands, which is the same fund that receives the royalties on the State's own retained mineral rights under ORS 273.780. Whether any oil or gas is currently produced in Oregon, and what the tax actually raises, were not read.

What does Oregon make an operator print on a royalty statement?

Eighteen specific words, and accepting the payment is treated as agreeing to them. ORS 324.510 provides that "All statements or settlement sheets for oil or gas shall have stamped or written thereon the following words: 'Gross production tax deducted and paid, and payee accepts such deduction and authorizes payment to the State of Oregon.'" A statute that dictates the exact wording on a royalty check stub, and turns acceptance of the money into an authorisation of the deduction, is not on this record anywhere else. The nearest thing is North Carolina's G.S. 105-187.83, which does something different and points the other way: it makes the owner of a royalty interest keep a record of all money received from each producing leasehold and a copy of every settlement sheet showing the volume and the severance tax deducted, and hand them to the Secretary of Revenue on request. Oregon's section sits in a short miscellaneous group at the end of the tax chapter with ORS 324.520, which puts reporting duties on three different parties: every person producing oil and gas in the state must furnish the Department of Revenue whatever production information it requires and may be made to install suitable measuring devices; every refinery operator processing oil or gas in the state must report quarterly; and every person purchasing or storing oil must report quarterly on the location, identity, character and capacity of the storage receptacle. Reports are delinquent if not filed by the forty-fifth day after the quarter, and ORS 324.520(4) sets the penalty at $25 for each day of failure or refusal. Whether the stamped words have ever been litigated, and what a payee achieves by striking them out, were not read.

What happens to unclaimed Oregon royalties?

They go to the State Treasurer under the general catch-all, because Oregon's unclaimed property act does not mention minerals at all. That was established by enumeration rather than by a search. The instrument is ORS chapter 98, "Lost, Unclaimed or Abandoned Property; Vehicle Towing", 322,865 characters fetched in one request, which contains the Uniform Disposition of Unclaimed Property Act at sections 98.302 to 98.436. Counted over the whole chapter: "mineral" zero, "royalty" zero, "oil" zero. "Gas" returns exactly one hit and it is "gas mileage", in the vehicle towing sections, which confirms the zeros rather than qualifying them. The controls are what make them mean something: "dividend" four, "safe deposit" three, "wages" thirteen, "utility" eight, "insurance" twenty-eight, "escheat" thirty-eight and "three years" twelve. So there is no definition of mineral proceeds, no separate abandonment period for royalties, bonuses, shut-in payments or delay rentals, and no suspense-account rule for an operator holding money for an owner it cannot find. North Carolina, Texas, Colorado and North Dakota all have one; Oregon has none, so the substance-specific protections those states carry, North Carolina's bar on a property finder taking a slice of the underlying minerals among them, have no Oregon equivalent. A suspended Oregon royalty falls instead to ORS 98.342(1): intangible personal property not otherwise covered, held or owing in the ordinary course of the holder's business and unclaimed for more than three years after it became payable or distributable, is presumed abandoned. Subsection (2) adds that property is payable or distributable notwithstanding the owner's failure to make demand or to present any required document, so never asking does not stop the clock. The limit: this is a whole-chapter count over the chapter that contains the act, and it cannot exclude a mineral-proceeds provision sitting in some other chapter, which was not looked for.
