A public record of who owns what is under the ground

California mineral rights

Verified
Jul 31 2026

The short answer

California can end a dormant mineral right, and of the states on this record that can end one, it is the hardest to lose an interest in. Three conditions must all be satisfied for the twenty years immediately before the action: no production and no operations affecting the minerals, no separate property tax assessment on the mineral right or no tax paid on one, and no instrument creating, reserving, transferring or otherwise evidencing the right recorded. Satisfying any single one of the three defeats the whole claim.

Nothing happens automatically either. The surface owner has to bring an action in the superior court and win it, in the manner of a quiet title suit. And even once that action is under way, the court must let the mineral owner record a late notice of intent to preserve as a condition of dismissing it, on paying the surface owner's litigation expenses and a reasonable attorney's fee.

Can California mineral rights be lost by not using them?

Yes, but it is harder here than in any other state on this record that can lapse an interest, and it takes a lawsuit. The owner of real property subject to a mineral right may bring an action to terminate it if the right is dormant, and a mineral right is dormant only if all of three conditions are satisfied for the twenty years immediately preceding the action.

The three are: no production of the minerals and no exploration, drilling, mining, development or other operations affecting them, whether on or below the surface of that property or on other property and whether or not pooled or unitized with it; no separate property tax assessment of the mineral right, or if one is made, no taxes paid on it; and no instrument creating, reserving, transferring or otherwise evidencing the mineral right recorded. Because they are cumulative, a mineral owner beats the action by showing any one of them is not met.

A notice of intent to preserve can be recorded at any time, and it does not need a legal description: it may refer generally and without specificity to any or all mineral rights the claimant claims in any real property in the county. If the twenty years have already run and the suit has been filed, the court still must permit a late notice as a condition of dismissal, on payment of the surface owner's litigation expenses. When a termination order does come, it is equivalent for all purposes to a conveyance of the mineral right to the owner of the real property.

dormancy

A dormant mineral right can be ended, but the surface owner must sue and all three conditions must hold for twenty years

verified

Cal. Civ. Code § 883.220

The owner of real property subject to a mineral right may bring an action to terminate the mineral right if it is dormant. A mineral right is dormant only if ALL of three conditions are satisfied for the twenty years immediately preceding the commencement of the action: there is no production of the minerals and no exploration, drilling, mining, development or other operations affecting them, whether on or below the surface of that property or on other property and whether or not unitized or pooled with it; no separate property tax assessment is made of the mineral right, or if one is made no taxes are paid on it; and no instrument creating, reserving, transferring or otherwise evidencing the mineral right is recorded. The action is brought in the superior court of the county where the property is, in the same manner and subject to the same procedure as a quiet title action so far as applicable. A mineral right terminated under the article is unenforceable and deemed to have expired, and the court order is equivalent for all purposes to a conveyance of the mineral right to the owner of the real property. The article applies to all mineral rights whether executed or recorded before, on or after January 1, 1985.

For the purpose of this article, a mineral right is dormant if all of the following conditions are satisfied for a period of 20 years immediately preceding commencement of the action to terminate the mineral right

Checked July 31, 2026. Read at Civil Code sections 883.210, 883.220, 883.240, 883.260 and 883.270. Two things distinguish this from the other lapse statutes on this record and both make it harder to lose a California interest. The conditions are CONJUNCTIVE, so a mineral owner defeats the whole thing by satisfying any one of the three: producing, being separately assessed and paying the tax, or having any instrument evidencing the right recorded in the period. Michigan, Indiana and Kansas all run off a single list of qualifying uses where doing any one is enough to save you, which sounds similar but is not: there the surface owner needs only the absence of every listed use, here the surface owner needs the absence of all three categories at once, and the third is satisfied by a recording that nobody had to make for this purpose. And nothing happens automatically. Michigan vests the interest with no warning and Indiana extinguishes it on the clock alone; California requires the surface owner to file a quiet title action in the superior court and win it. What the order does when it comes is stated in unusually plain terms: it is equivalent for all purposes to a conveyance of the mineral right to the surface owner.

dormancy

The termination chapter does not reach a mineral right reserved to the United States, or one held by the state

verified

Cal. Civ. Code § 883.120

The chapter does not apply to a mineral right reserved to the United States, whether in a patent, pursuant to federal law, or otherwise, nor to an oil or gas lease, mining claim or other mineral right of a person entitled pursuant to such a reservation, to the extent the marketable title provisions provide. It also does not apply to a mineral right of the state or a local public entity, or of any other person, to that same extent. Separately, nothing in the chapter limits or affects the common law governing abandonment of a mineral right, or any other procedure provided by statute for clearing an abandoned mineral right from title to real property.

This chapter does not apply to a mineral right reserved to the United States (whether in a patent, pursuant to federal law, or otherwise) or to an oil or gas lease, mining claim, or other mineral right of a person entitled pursuant thereto, to the extent provided in Section 880.240.

Checked July 31, 2026. Read at Civil Code sections 883.120 and 883.130, and both belong on the page for the same reason: they tell a reader what this chapter cannot do for them. The first is the connection between this page and the federal record on this site. A California surface owner whose minerals were reserved to the United States in the patent cannot use this article at all, and no amount of dormancy will change that, which is the same conclusion the federal reservations page reaches by a different route. The second matters because it stops the article being read as a complete code: the common law of abandonment survives it, and so does any other statutory clearing procedure. So the existence of this chapter is not authority that a dormant California mineral right can only be ended this way. WHAT IS NOT READ: section 880.240, which both exclusions are measured by, and the common law of abandonment itself, since nothing was fetched from a California court.

What a California mineral right is, and what a lease is deemed to allow

severance

California defines a mineral right to reach every form the interest can take, and to carry surface rights with it

verified

Cal. Civ. Code § 883.110

For the chapter that governs terminating a dormant mineral right, a mineral right means an interest in minerals, regardless of character, whether fugacious or nonfugacious, organic or inorganic, that is created by grant or reservation, regardless of form, whether a fee or lesser interest, mineral, royalty or leasehold, absolute or fractional, corporeal or incorporeal, and it includes express or implied appurtenant surface rights.

As used in this chapter, "mineral right" means an interest in minerals, regardless of character, whether fugacious or nonfugacious, organic or inorganic, that is created by grant or reservation, regardless of form, whether a fee or lesser interest, mineral, royalty, or leasehold, absolute or fractional, corporeal or incorporeal, and includes express or implied appurtenant surface rights.

Checked July 31, 2026. Read at Civil Code section 883.110. This is the widest statutory definition of a severed mineral interest on this record and it is worth reading twice, because most of the definitions here are narrow on purpose. New Mexico defines an owner by the right to drill. Montana defines an oil and gas estate as ownership of what lies under a tract. Louisiana refuses the category altogether. California instead sweeps in every axis on which such an interest can vary: what the substance is, how the interest was created, what form it takes, whether it is whole or fractional, and whether it is corporeal or incorporeal. The last clause is the one to carry away, because it decides arguments rather than describing them: the mineral right INCLUDES express or implied appurtenant surface rights. A California mineral owner's right to get at the minerals is inside the definition of the thing they own. Note the scope limit in the section's own opening words: this definition governs that chapter, so it is the definition used when deciding what can be terminated as dormant, and this record does not extend it beyond that.

severance

When a mineral lease ends the lessee has thirty days from a demand to clear it off the title

verified

Cal. Civ. Code § 883.140

If the term of a mineral right lease has expired or the lease has been abandoned by the lessee, the lessee must within thirty days after demand by the lessor execute, acknowledge and deliver, or cause to be recorded, a deed quitclaiming all interest in the mineral rights the lease covered. Where the expiration or abandonment covers less than the lessee's whole interest, the lessee must deliver an appropriate instrument or notice of surrender or termination covering the part that has ended. A lessee who fails to comply is liable for all damages the lessor sustains as a result, including court costs and reasonable attorney's fees in an action to clear title, and forfeits a further one hundred and fifty dollars to the lessor. Lessee includes an assignee or other successor, and lessor includes a successor, heir or grantee. Nothing in the section makes the quitclaim, or a demand for one, a condition precedent to an action to clear the lessor's title.

If the lessee fails to comply with the requirements of this section, the lessee is liable for all damages sustained by the lessor as a result of the failure, including, but not limited to, court costs and reasonable attorney's fees in an action to clear title to the lessor's interest.

Checked July 31, 2026. Read at Civil Code section 883.140. This addresses a complaint that turns up constantly and that most of this record cannot answer: a lease that everyone agrees is over but that still sits in the records clouding the title, because nobody made the lessee release it. California puts a thirty day clock on it, runs the clock from the lessor's demand rather than from the expiry, binds assignees and successors on both sides, and makes the sanction attorney's fees rather than a token. The last subsection is the one a lawyer will want: the demand is NOT a condition precedent, so a lessor who never made one has not lost the right to sue to clear title. WHAT IS NOT READ: whether a California court has construed what abandonment by the lessee means here, and the fixed sum has not been adjusted in the text as read, so it is stated as the statute states it rather than in present-day terms.

Absent express words to the contrary a lease is deemed to authorise whatever a prudent operator would do

verified

Cal. Pub. Res. Code § 3106

It is declared a policy of the state that the grant in an oil and gas lease or contract to a lessee or operator of the right or power, in substance, to explore for and remove all hydrocarbons from any lands in the state is, in the absence of an express provision to the contrary in the lease or contract, deemed to allow the lessee or contractor and their successors or assigns to do what a prudent operator using reasonable diligence would do, having in mind the best interests of the lessor, the lessee and the state in producing and removing hydrocarbons. That is expressly declared to include the injection of air, gas, water or other fluids into the productive strata, the application of pressure, heat or other means to reduce the viscosity of the hydrocarbons, the supplying of additional motive force, and the creating of enlarged or new channels for underground movement of hydrocarbons into production wells, in each case where the method has been approved by the supervisor. Nothing in the section imposes a legal duty on the lessee or contractor to conduct any of those operations. The supervisor is separately directed to supervise drilling, operation, maintenance and abandonment so as to prevent, as far as possible, damage to life, health, property and natural resources.

the grant in an oil and gas lease or contract to a lessee or operator of the right or power, in substance, to explore for and remove all hydrocarbons from any lands in the state, in the absence of an express provision to the contrary contained in the lease or contract, is deemed to allow the lessee or contractor, or the lessee's or contractor's successors or assigns, to do what a prudent operator using reasonable diligence would do

Checked July 31, 2026. Read at Public Resources Code section 3106, subsections (a) and (b). This record now holds three statutory rules of construction for mineral instruments and they do not point the same way, which is the reason to publish this one. Kentucky's constitution reads an old coal severance DOWN, presuming the parties meant only the extraction methods commonly in use in the area at the time. Virginia's code settles what a coal conveyance does not reach at all. California reads an oil and gas lease UP: silence in the instrument becomes permission to do what a prudent operator would do, and the statute then lists enhanced recovery techniques the parties may never have contemplated. Three limits are in the text and each matters. It applies to a lease or contract rather than to a severance deed. It yields to an express provision to the contrary, so the drafting cure is available. And the listed methods require the supervisor's approval. Note also what the section refuses to do: it creates no duty to develop, which is the opposite of what Kansas legislated. WHAT IS NOT READ: whether a California court has applied subsection (b), and what "best interests of the lessor" has been held to require.

The comparison with Kentucky's and Virginia's rules of construction is in the note above. What matters more for most readers is the limit on the front of the section, which is easy to read past: it construes a LEASE or contract, not a severance deed. So it tells you what a lessee may do under an instrument you or your predecessor signed. It does not tell a California landowner what the owner of a severed mineral estate may do to their surface where there is no lease between them, which is the situation most of this site is about. California's answer to that question is not in the code sections read here; it is in the common law, and nothing was fetched from a California court, so this page does not supply it. That gap is named below rather than papered over, and it is the single most useful thing missing from this page.

What an operator owes you, and why it is not about owning the surface

surface-use

What California owes you turns on how close you are to the well, not on whether you own the minerals or the surface

verified

Cal. Pub. Res. Code § 3284

California defines a surface property owner as the owner of real property shown on the latest equalized assessment roll, or the owner of record according to the county assessor or tax collector where more recent information exists. Two duties are then keyed to distance rather than to ownership of the mineral estate. In a health protection zone, meaning the area within 3,200 feet of a sensitive receptor such as a residence, a school, a park, a hospital, a prison or any building housing a business open to the public, an operator must before commencing work requiring a notice of intention contact property owners AND TENANTS within a 3,200 foot radius of the wellhead in writing with a record of delivery, at least thirty days beforehand, and offer to sample and test water wells or surface water on their property before and after drilling. If sampling is requested in time, drilling may not commence until a baseline sample has been collected, and the operator bears the cost. Separately, for a well stimulation treatment, it is the policy of the state that a copy of the approved permit and information on the available water sampling and testing be provided to every tenant of the surface property and every surface property owner whose property line is within a 1,500 foot radius of the wellhead or within 500 feet of the horizontal projection of the well, the notification is performed by an independent entity the operator contracts and the division may audit, and the treatment may not commence before thirty calendar days after the copies are provided.

Before commencing any work that requires a notice of intention under Section 3203 in the health protection zone, the operator shall contact property owners and tenants within a 3,200-foot radius of the wellhead in writing with a record of delivery and offer to sample and test water wells or surface water on their property before and after drilling.

Checked July 31, 2026. Read at Public Resources Code sections 3156, 3160 and 3280 to 3284. THIS RULE CORRECTS A DRAFT OF THIS PAGE THAT WAS WRONG, and the mistake is worth recording because it is the mistake this site is built to avoid. The chapter was searched for the phrase 'surface owner', which appears in it zero times, and the first draft concluded that California gives a surface owner nothing. California says 'surface PROPERTY owner', and once that is read there is a good deal here. The correction changes the finding rather than only the wording. What California actually does is unlike the surface damage states on this record. Colorado, Montana, New Mexico, North Dakota, West Virginia, Kentucky and Wyoming all attach the operator duty to the person who owns the surface, because the premise is a split estate and the question is what one estate owes the other. California attaches it to PROXIMITY, and extends it to tenants, who own nothing at all. A renter a thousand feet from the wellhead is owed the notice and may request the water testing; a surface owner two miles away is owed neither. The subject of the protection is a person near a well, not an estate in land. Note also what is absent: nothing read in the chapter gives a California surface owner compensation for surface damage. Every use of 'damages' and of 'compensation' in the chapter was read, and they concern blowout insurance, eminent domain security, civil penalties and liability for violations, not a landowner damages regime. WHAT IS NOT READ: the notice of intention section itself, the local ordinances that in California often decide these questions, and any decision applying the health protection zone article, which took effect in June 2024 after a referendum petition against it was withdrawn.

The consequence is worth stating in the terms a reader will care about, because it cuts both ways and neither way is obvious. If you own surface a long way from any wellhead, California's oil and gas chapter gives you no notice, no water testing and no compensation, whatever your deed says about the minerals underneath. If you rent a house within the radius, you are owed written notice with a record of delivery, thirty days before the work, and you can require the operator to sample and test the water at its own cost before it starts. Every other surface protection statute on this record asks who owns the land. California asks how close the people are.

Where ownership is recorded

Void against a later good faith purchaser for value who records first, and against a judgment affecting title

verified

Cal. Civ. Code § 1214

Every conveyance of real property or an estate for years in it, other than a lease for a term not exceeding one year, is void as against any subsequent purchaser or mortgagee of the same property or any part of it, in good faith and for a valuable consideration, whose conveyance is first duly recorded, and as against any judgment affecting the title unless the conveyance was duly recorded before the record of notice of action. Every conveyance acknowledged or proved and certified and recorded as prescribed by law is, from the time it is filed with the recorder for record, constructive notice of its contents to subsequent purchasers and mortgagees, and a certified copy of such a recorded conveyance may be recorded in any other county with the same force and effect as the original. Conveyance for these two sections embraces every instrument in writing by which any estate or interest in real property is created, aliened, mortgaged or encumbered, or by which the title to any real property may be affected, except wills.

Every conveyance of real property or an estate for years therein, other than a lease for a term not exceeding one year, is void as against any subsequent purchaser or mortgagee of the same property, or any part thereof, in good faith and for a valuable consideration, whose conveyance is first duly recorded

Checked July 31, 2026. Read at Civil Code sections 1213, 1214 and 1215. This is the race-notice shape, the same as Colorado, Michigan, Montana, North Dakota, Alaska and Wyoming: the later claimant must be in good faith, must have given value, and must have recorded first. Two California specifics are worth carrying. The priority rule reaches JUDGMENTS as well as purchasers, so an unrecorded conveyance also loses to a judgment affecting the title unless it was recorded before the notice of action went on the record, which is a limb this record has not seen stated in the same breath elsewhere. And the definition section matters more here than the usual boilerplate, because it settles that a mineral deed or reservation is a conveyance for these purposes: it embraces every instrument by which any estate or interest in real property is created, aliened, mortgaged or encumbered, or by which title may be affected, and excludes only wills. WHAT IS NOT READ: any California decision applying the sections, and the priority rules for a mineral right specifically as against the general marketable title provisions.

The charge on production, and the severance California does tax

California charges on mineral production, from Cal. Pub. Res. Code § 3402 and the Revenue and Taxation Code, read July 31, 2026. Only the lithium rows are rates the statute fixes; the oil and gas rows are set annually by the regulator.
What is chargedRateNotes
Oil, per barrel producedrate set annually to fund the regulatorA uniform rate per barrel for the preceding calendar year, apportioned among the operator and the owners of royalty and other interests and withheld by the operator. The rate is not in the statute: the department determines it by June 15 each year to raise what it estimates it needs. Cal. Pub. Res. Code 3402, 3410 and 3412.
Gas, per ten thousand cubic feet producedrate set annually to fund the regulatorSame structure as oil, excluding gas used for recycling or otherwise in oil-producing operations. Cal. Pub. Res. Code 3403.

Lithium, above thirty thousand tonneseight hundred dollars per metric tonA new permit holder is assumed to have already extracted thirty thousand tonnes, so a transfer does not reset the ladder. Rates are CPI adjusted annually from 2025. Cal. Rev. & Tax. Code 47010(b) and (c).
Oil and gas severance or production taxNone foundThe contents of division 2 of the Revenue and Taxation Code, headed Other Taxes, were enumerated and hold 51 parts. None is an oil and gas severance or production tax. Part 18.5 is the Timber Yield Tax and part 25 the Lithium Extraction Tax Law.
severance-tax

California does not tax oil and gas severance, and instead levies a per unit charge that funds the regulator

verified

Cal. Pub. Res. Code § 3402

California imposes annually on the person operating each oil well in the state, or owning royalty or other interests in respect of the production from the well, a charge computed at a uniform rate per barrel of oil produced in the preceding calendar year, and a corresponding charge on each gas well at a uniform rate per ten thousand cubic feet. The charge is apportioned among all those persons in fractional amounts proportionate to their respective fractional interests in the production, but the whole of it is payable by the operator, who withholds the royalty and other interest owners' proportionate shares from the amounts otherwise payable or deliverable to them. The rate is not fixed in the statute: each year the department, acting with the Department of Finance, estimates what will be required to carry out the chapter, then determines the rate or rates that will produce that sum, and must post the information supporting the rate on a publicly available part of its website. The proceeds are used exclusively to support the department that supervises oil and gas operations, the state and regional water boards for their oil and gas related activities, and the air board and the Office of Environmental Health Hazard Assessment for theirs. The charge is in addition to any and all other charges, taxes, assessments or licenses.

There shall annually be imposed upon the person operating each oil well in this state, or owning royalty or other interests in respect to the production from the well, a charge which shall be payable to the Treasurer and which shall be computed at a uniform rate per barrel of oil produced from the well for the preceding calendar year.

Checked July 31, 2026. Read at Public Resources Code sections 3400, 3401, 3402, 3403, 3404, 3410 and 3412. Two findings sit here and the second is the surprising one. FIRST, on the question this site asks of every state, California answers it in the imposing section rather than leaving it to a withholding provision: the charge is imposed on the operator OR on anyone owning royalty or other interests, it is apportioned by fractional interest, and the operator withholds the royalty owner's share. So it comes out of the cheque. SECOND, this is not a severance tax and does not behave like one. It is a cost recovery levy whose rate is whatever will fund the regulator that year, so it moves with the department's budget rather than with the price of oil or the value of what is produced. Pennsylvania is the only other state on this record with no charge measured on value or volume at state level, and Pennsylvania's is a flat per well fee a county may elect to impose; California's is measured on volume but set by the cost of regulation. THE NEGATIVE, and how it was established: the contents of division 2 of the Revenue and Taxation Code, headed Other Taxes, were enumerated and hold 51 parts. There is no oil and gas severance or production tax among them. There is a Timber Yield Tax at part 18.5 and a Lithium Extraction Tax Law at part 25, so California does tax the severance of two things; oil and gas are not among them. WHAT IS NOT READ: the current rate, which is set annually and was not fetched; ad valorem property taxation of mineral interests under division 1; and the oil spill response, prevention and administration fees at part 24.

severance-tax

The severance California does tax by the tonne is lithium, on a lifetime cumulative bracket

verified

Cal. Rev. & Tax. Code §§ 47010 to 47020 (Lithium Extraction Tax Law)

Beginning January 1, 2023 a producer must pay a lithium extraction excise tax on each metric ton of lithium carbonate equivalent extracted from geothermal fluid, spodumene ore, rock, minerals, clay or any other naturally occurring substance in the state. The rate rises with lifetime cumulative production by that producer rather than with price: four hundred dollars per metric ton up to twenty thousand tonnes, six hundred over twenty thousand and up to thirty thousand, and eight hundred above thirty thousand. Where the permit or ownership of a mine, extraction facility or well changes, the cumulative amount previously reported is assumed to be thirty thousand metric tons. From January 1, 2025 the rates are adjusted annually by the department for cost of living by reference to the California Consumer Price Index for all urban consumers, rounded to the nearest whole dollar. Lithium and lithium compounds are converted to lithium carbonate equivalent by statutory conversion factors, including 5.323 for lithium itself and 0.871 for lithium chloride. Except for sales and use taxes, the taxes imposed are in lieu of all county, municipal or district taxes on lithium extraction or storage by producers, and the Legislature states its intent to pre-empt inconsistent local taxes.

a producer shall pay a lithium extraction excise tax upon each metric ton of lithium carbonate equivalent extracted from geothermal fluid, spodumene ore, rock, minerals, clay, or any other naturally occurring substance in this state

Checked July 31, 2026. Read in the Lithium Extraction Tax Law at Revenue and Taxation Code sections 47010, 47015 and 47020. This is on the record for two reasons and neither is that anyone reading this page owns lithium. The first is that it completes the tax picture honestly: it would be wrong to say California does not tax mineral severance, because it does, and the way to state that accurately is to name what it taxes. The second is that the design is unlike any production tax on this record. Every other rate here moves with price or with the value of the product; this one moves with how much the producer has ever extracted, on a lifetime cumulative ladder, so the rate a producer pays reflects the maturity of their operation rather than the market. The transfer rule closes the obvious avoidance route by presuming a new permit holder has already extracted thirty thousand tonnes, which puts them straight into the top bracket. WHAT IS NOT READ: the definitions and administration chapters of the same part, any exemptions, the current inflation-adjusted rate, and the Timber Yield Tax at part 18.5, which is the other severance California taxes and which this record has seen only as a heading in the contents.

The row worth pausing on is the last one in the table, because it is a negative and negatives need an instrument. The contents of the division of the Revenue and Taxation Code headed Other Taxes were enumerated and hold fifty-one parts. None of them is an oil and gas severance or production tax. Two of them are severance taxes on something else: the Timber Yield Tax, which this record has seen only as a heading, and the Lithium Extraction Tax Law, which it has read. So the accurate statement is not that California declines to tax mineral severance, but that it taxes the severance of timber and of lithium and not that of oil and gas. What mineral rights are worth sets the state structures side by side.

The regulator, and what it publishes

The regulator is the California Geologic Energy Management Division, Department of Conservation, CalGEM. It publishes:

  • Well Finder, a map tool giving the location, status and history of wells, alongside its other data tools and WellSTAR
  • Oil and gas permits, and a separate section on well stimulation and hydraulic fracturing
  • The idle well programme, with compliance schedules to test for leaks and to plug and abandon, and engineering analyses for wells unused for fifteen years or more
  • Underground injection control material, including aquifer exemptions and continuous well pressure monitoring requirements
  • Its Office of Enforcement, a public transparency office, an oil and gas outreach listserv, and Project Plug, on legacy wells and facilities

Checked July 31, 2026. Read from the division's own pages. Two things about this regulator are worth knowing before you use it. It funds itself out of the charge on production described further down this page, so the levy a royalty owner sees withheld and the body publishing this data are the same arrangement seen from two ends. And its idle well programme is unusually concrete for a public-facing regulator page: compliance schedules to test for leaks and to plug and abandon, and engineering analyses required for wells not in use for fifteen years or more. As everywhere else on this site, none of it is a register of mineral ownership.

What this page does not answer about California

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

  • The current per barrel and per ten thousand cubic feet rates. They are set by the department each June to raise what it estimates it needs, and the determination for the current year was not fetched. This page publishes the mechanism and not a figure.
  • Ad valorem property taxation of mineral interests, which sits in division 1 of the Revenue and Taxation Code and is where a charge on a California mineral interest is most likely to be felt. Nothing in division 1 was read.
  • The Timber Yield Tax at part 18.5 of division 2, which is the other severance California taxes. It was seen as a heading in the contents and its text was not read, so nothing about its rate or reach is stated here.
  • The definitions, exemptions and administration chapters of the Lithium Extraction Tax Law, and the oil spill response, prevention and administration fees at part 24.
  • Local ordinances. California is the state on this record where city and county regulation of oil and gas is most active and most litigated, and this page reads state law only. An answer about a particular parcel may turn entirely on the local rules.
  • Section 880.240, which measures both exclusions in the termination chapter, and section 880.330 and section 880.370, which govern the contents of a notice of intent to preserve and the recording grace period the article is subject to.
  • The common law of abandonment of a mineral right, which the chapter expressly leaves untouched, and any other statutory procedure for clearing an abandoned mineral right from title. Both are named in the code and neither was read.
  • What a California mineral owner may do to the surface where there is no lease between them and the landowner. The rule of construction on this page construes a lease or contract, not a severance deed, and the proximity duties run to whoever is near a well rather than to a surface owner as such. So the ordinary split estate question is answered by California common law, and nothing was fetched from a California court. This is the single most useful thing missing from this page.
  • Whether California gives a surface owner a right to compensation for surface damage anywhere outside the oil and gas conservation chapter. What was established is narrower and is on the page: the chapter itself has no landowner damages regime, and its owner-facing duties are keyed to proximity to the well rather than to ownership. That is a fact about one chapter, read whole, and not about the whole of California law.

Every state on this record is listed with its status. Whether mineral rights expire sets California beside the other states that can end an interest for non use.

Questions people actually ask

Do California mineral rights expire if you do not use them?

They can be terminated, but only through a lawsuit and only on a test that is harder to satisfy than any other lapse statute on this record. The owner of real property subject to a mineral right may bring an action to terminate it if it is dormant, and it is dormant only if all three of the following are true for the twenty years immediately preceding the commencement of the action: there is no production of the minerals and no exploration, drilling, mining, development or other operations that affect them, whether on or below the surface of the property or on other property and whether or not unitized or pooled with it; no separate property tax assessment is made of the mineral right, or if one is made no taxes are paid on the assessment; and no instrument creating, reserving, transferring or otherwise evidencing the mineral right is recorded. Because the conditions are cumulative, the mineral owner defeats the action by showing any one of them is not satisfied. The action is brought in the superior court of the county where the property is, in the manner of a quiet title action. A mineral right terminated this way is unenforceable and deemed to have expired, and the order is equivalent for all purposes to a conveyance of the right to the owner of the real property.

What do I file to keep a California mineral right alive?

A notice of intent to preserve, and California is unusually forgiving about both its contents and its timing. It may be recorded at any time. On contents, it does not need the statement of the character of the interest, the record location of the documents creating it, or the legal description of the property that the general marketable title provisions would otherwise require: it may refer generally and without specificity to any or all mineral rights the claimant claims in any real property situated in the county. That is a real concession to the commonest situation, an inherited fractional interest whose owner does not know precisely what they hold or where. On timing, a right is not dormant if such a notice was recorded within the twenty years before the action began. And if that was missed, the court in the termination action shall permit the owner to record a late notice as a condition of dismissing the action, on payment into court, for the surface owner's benefit, of the litigation expenses attributable to the mineral right the notice covers, meaning recoverable costs and expenses reasonably and necessarily incurred in preparation for the action including a reasonable attorney's fee. What this record has not read is section 880.330, which sets the general contents of such a notice, or section 880.370, the recording grace period the article is subject to.

Does the California dormancy statute reach federal mineral reservations?

No, and that is stated in the chapter itself. The chapter does not apply to a mineral right reserved to the United States, whether in a patent, pursuant to federal law or otherwise, nor to an oil or gas lease, mining claim or other mineral right of a person entitled pursuant to such a reservation, to the extent the general marketable title provisions provide. It likewise does not apply to a mineral right of the state or a local public entity. So a California surface owner whose minerals were reserved to the United States in the original patent cannot use this article at all, however long the reservation has sat unused. That is the same conclusion this site's federal record reaches from the other direction. One further limit is in the next section and it points the opposite way: nothing in the chapter limits or affects the common law governing abandonment of a mineral right, or any other statutory procedure for clearing an abandoned mineral right from title. So the existence of this article is not authority that it is the only route. Neither the cross-referenced section that measures the exclusions nor the common law of abandonment was read for this record.

What is a mineral right under California law?

The definition is the widest on this record. For the chapter governing termination of a dormant mineral right, a mineral right means an interest in minerals, regardless of character, whether fugacious or nonfugacious, organic or inorganic, that is created by grant or reservation, regardless of form, whether a fee or lesser interest, mineral, royalty or leasehold, absolute or fractional, corporeal or incorporeal, and it includes express or implied appurtenant surface rights. Every axis on which such an interest can vary is swept in: the substance, how the interest arose, what form it takes, whether it is whole or fractional, and whether it is corporeal or incorporeal. The final clause is the one that decides arguments rather than describing them, because it puts the right to get at the minerals inside the definition of the thing owned. One limit to keep in view: the section opens with the words "as used in this chapter", so this is the definition used when deciding what can be terminated as dormant, and this record does not extend it beyond that chapter.

Does a California operator have to notify me before drilling?

It depends on how close you are, not on what you own. In a health protection zone, meaning the area within 3,200 feet of a sensitive receptor such as a residence, a school, a park, a hospital, a prison or any building housing a business open to the public, an operator must before commencing work requiring a notice of intention contact property owners and tenants within a 3,200 foot radius of the wellhead, in writing with a record of delivery, at least thirty days beforehand, and offer to sample and test water wells or surface water on their property before and after drilling. If sampling is requested in time, drilling may not commence until a baseline sample has been collected, and the operator bears the cost. For a well stimulation treatment the radius is different and so is the mechanism: it is the policy of the state that a copy of the approved permit and information on the available water sampling and testing be provided to every tenant of the surface property and every surface property owner whose property line is within 1,500 feet of the wellhead or within 500 feet of the horizontal projection of the well, the notification is carried out by an independent entity the operator contracts and the division may audit, and the treatment may not begin for thirty calendar days afterwards. Note who is covered: tenants as well as owners. And note who is not: a surface owner outside the radius.

Does California have an oil and gas severance tax?

Nothing read for this record levies one. What California levies instead is an annual charge on the person operating each oil well, or owning royalty or other interests in the production from it, computed at a uniform rate per barrel produced in the preceding calendar year, and a corresponding charge per ten thousand cubic feet on gas wells. The charge is apportioned among all those persons in proportion to their fractional interests, but the whole of it is payable by the operator, who withholds the royalty and other interest owners' shares from what would otherwise be paid to them, so it does come out of a royalty cheque. The rate is not in the statute. Each year the department, acting with the Department of Finance, estimates what it will need to carry out the chapter, then determines the rate that will produce that sum, and must post the supporting information on its website. The proceeds fund the division that supervises oil and gas operations together with the water boards, the air board and the Office of Environmental Health Hazard Assessment for their oil and gas related work. So it is a cost recovery levy that moves with the regulator's budget rather than with the price of oil. The negative was established by enumerating the fifty-one parts of the division of the Revenue and Taxation Code headed Other Taxes; none is an oil and gas severance tax, though two are severance taxes on other things.

What does California tax the severance of, if not oil and gas?

Lithium, by the tonne, and timber. The lithium extraction excise tax has applied since January 1, 2023 to each metric ton of lithium carbonate equivalent extracted from geothermal fluid, spodumene ore, rock, minerals, clay or any other naturally occurring substance in the state. Its design is unlike any production tax on this record because the rate tracks the producer rather than the market: four hundred dollars per metric ton for the first twenty thousand tonnes that producer has ever extracted, six hundred over twenty thousand and up to thirty thousand, and eight hundred above that, on a lifetime cumulative ladder. Where the permit or ownership of a mine, extraction facility or well changes, the cumulative amount previously reported is assumed to be thirty thousand metric tons, which puts a new holder straight into the top bracket and closes the obvious avoidance route. From January 1, 2025 the rates are adjusted annually for cost of living by the California Consumer Price Index for all urban consumers. Lithium compounds are converted to lithium carbonate equivalent by conversion factors set out in the statute. Except for sales and use taxes the tax is in lieu of all county, municipal and district taxes on lithium extraction or storage by producers. The Timber Yield Tax is the other one, and this record has seen it only as a heading in the code's contents, so nothing about its rate or reach is stated here.

My California mineral lease has expired but it is still on the title. What can I do?

Demand a quitclaim, and there is a statute with teeth behind the demand. If the term of a mineral right lease has expired, or the lease has been abandoned by the lessee, the lessee must within thirty days after demand by the lessor execute, acknowledge and deliver, or cause to be recorded, a deed quitclaiming all interest in the mineral rights the lease covered. Where only part of the lessee's interest has ended, the lessee must instead deliver an appropriate instrument or notice of surrender or termination covering that part. A lessee who fails to comply is liable for all damages the lessor sustains as a result, including court costs and a reasonable attorney's fee in an action to clear title, and forfeits a further one hundred and fifty dollars. Both sides' successors are covered: lessee includes an assignee or other successor in interest, and lessor includes a successor in interest, heir or grantee. The last subsection is the one worth knowing if you never made a demand: nothing in the section makes the quitclaim deed, or a demand for one, a condition precedent to an action to clear title to the lessor's interest. What this record has not read is whether any California court has construed what abandonment by the lessee means here.
