Mineral rights in California are governed by California property and oil and gas law and regulated by the California Geologic Energy Management Division (CalGEM). Whether a severed interest can lapse from non-use, how oil and gas production is taxed, and how land is legally described all follow California-specific rules — set out below with the California authorities that govern them.
CalGEM — renamed from DOGGR, so older division orders and title work still say "DOGGR" — permits California wells and publishes the production records we check on every California evaluation. CalGEM.
A surface owner may bring an action to terminate a mineral right that is dormant, and a right is dormant only if all three conditions held for the twenty years immediately preceding the action: no production or operations affecting the minerals on the property or on pooled or unitized property; no separate property tax assessment of the mineral right, or if assessed, no taxes paid; and no recorded instrument creating, reserving, transferring, or evidencing the right. Because all three legs are required, paying an assessment or recording an instrument defeats it. An owner may also record a notice of intent to preserve at any time — and uniquely, that notice may refer generally to any or all mineral rights the claimant holds anywhere in the county, making it cheap, broad insurance. (See Cal. Civ. Code §§ 883.210–883.270.)
California levies no statewide severance tax on oil and gas production. What it has is a small annual Oil and Gas Assessment charged to operators, set each June by dividing the regulator's budget by prior-year assessable production and applied per barrel of oil and per 10,000 cubic feet of gas. Because it funds the regulator and is billed to producers, it does not behave like a severance tax deducted from a royalty check.
The per-barrel rate is reset annually and has risen substantially over time, so any specific figure should be checked against the current year. Confirm your own position with a CPA — this is published reference, not tax advice.
California counties administer ad valorem property taxes on producing oil and gas interests. Beyond the ordinary reason to pay a tax bill, there is a title reason specific to California: an unpaid separate assessment on a mineral right is one of the three conditions that together make an interest "dormant" and exposed to termination.
California is a public-land state surveyed under three principal meridians: Mount Diablo across the north and center, San Bernardino in the south, and Humboldt in the far northwest. But land confirmed to Spanish and Mexican grantees before statehood was never subdivided into sections, and those ranchos are described by patent name, metes and bounds, and recorded maps. Coastal and Southern California mineral descriptions frequently read "Rancho ___, as per map recorded in Book __ of Maps" rather than a section call, and title work in Los Angeles, Ventura, Santa Barbara, Orange, and Monterey routinely straddles both systems.
Oil and gas activity in California is concentrated in these plays and basins:
The facts above — who regulates, whether an idle interest can lapse, how production is taxed, and how land is described — are the California-specific rules that shape what you own and how it is protected. For the doctrines behind them see oil and gas law and the rule of capture; to compare states, see mineral rights by state. Buckhead Energy buys California mineral and royalty interests and prices them on the same regulator and production records described here. This is educational background, not legal advice; California oil and gas law is fact-specific, so consult a qualified California attorney about your interest.
