Sell Mineral Rights in California

California mineral ownership tends to be old, urban, and heavily regulated, three things that make it slower to close than a newer shale interest but not less real.

The interests we see out of California mostly trace back to fields that have been producing for the better part of a century: Kern County's San Joaquin valley fields like Kern River and Midway-Sunset, and the legacy Los Angeles basin fields including Wilmington and Long Beach. These aren't new plays with type curves, they're some of the longest-producing oil fields in the country, and the paperwork behind them reflects that.

Because so much of California production sits under or near dense population centers, permitting and local ordinance activity affects operators here in ways that don't apply in rural Texas or Oklahoma counties, and that regulatory backdrop is something we factor into how we underwrite continued production, beyond the current decline curve alone.

Why California title work runs long

Many Kern County and LA basin mineral severances date to the 1920s through 1950s, sometimes with multiple assignments, unitization agreements, and municipal lease overlays layered on top of the original deed. Add California's community property rules, which affect how interests pass between spouses and through probate, and a full title search here routinely takes longer than in a state with simpler courthouse records.

We budget for that upfront rather than promise a two-week close and then miss it. If your interest has been in the family since before 1970, we'll ask early whether there's ever been a full title opinion done, because finding one already on file can cut real time off the process.

Underwriting a legacy heavy-oil field

San Joaquin valley production, particularly the heavy oil fields, often relies on steam injection or other enhanced recovery methods to keep older wells economic, which means operating costs matter more to the underlying economics than they do in a typical light-oil shale well. We look at whether the operator has continued active EOR investment in your specific field, because that tells us more about the durability of future royalty payments than the well's raw decline curve alone.

LA basin urban fields carry their own wrinkle: some production sits on directionally drilled wells reaching under residential or commercial areas from a limited number of surface pads, so unit configuration and pooling matter more here than well-by-well analysis.

Regulatory activity we watch

California's permitting environment for new wells has tightened meaningfully over the past several years, particularly around setback distances from homes and schools in populated areas. That doesn't stop existing production, but it does mean we're conservative about assuming new infill drilling will refresh a legacy interest's decline curve. We price mostly off what's currently producing and documented, not a bet on future permits.

Our process for a California package

Send us your most recent division order or royalty statement and, if you have it, any prior title opinion or probate documentation. We'll pull the county recorder history ourselves in Kern or Los Angeles County and tell you plainly if we expect the closing timeline to run longer than usual because of the title's age.

Water flooding and disposal costs on older diatomite fields

Some Kern County production, particularly around the diatomite intervals near Belridge and McKittrick, relies on cyclic steam or water flood programs that carry ongoing injection and disposal costs distinct from a standard EOR steam field. Those costs, along with California's water rights and produced-water disposal rules, feed directly into how much an operator nets from a barrel of production and how committed they are likely to stay to a given lease over time.

We ask for the operator's current cost history where available on these fields, since a legacy interest sitting behind a field with escalating injection or disposal costs can see its net royalty compress even if gross wellhead volumes hold roughly steady, and we would rather price that risk explicitly than assume flat economics indefinitely.
