## Answer
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. Frequently asked questions Who buys mineral rights in California? Buckhead Energy buys mineral and royalty interests in California — producing or non-producing — and prices them on the same public regulator and production records described here. Buckhead Energy is a direct buyer, not a broker: a free written offer, buyer-paid closing, and no commission. Can I lose my mineral rights in California for non-use? 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. Who regulates oil and gas in California? California Geologic Energy Management Division. 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. How are California oil and gas royalties taxed? 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. How is California mineral property described? 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.
