Colusa, Williams, Grimes: we buy minerals and royalties throughout Colusa County, Sacramento Basin dry gas along the river.
Colusa County is rice ground over gas sands. The Grimes field crosses the river from Sutter County, Sycamore and Princeton sit upstream, and a dozen smaller fields dot the valley floor, all of it dry gas from Cretaceous sands that has been produced for generations and sold to the Bay Area. It is about as unglamorous as oil and gas gets, which is why the royalties here are undervalued by everyone, including the people who own them.
What produces here. CalGEM's 2023 annual report, the latest county table it has published, put Colusa County at 1,504,539 Mcf of gas and no oil for the year. CalGEM's WellSTAR records as of November 2026 show 139 active wells: California Resources Production Corporation operates 97, with Harvest Petroleum (14), Central Valley Gas Storage (12, the Princeton storage project), Royale Energy (10) and Drilling, Exploration and Operating (5) the others; the Grimes, Sycamore, Grimes West, Princeton, Buckeye, Moon Bend, Kirk, Lone Star and Williams fields hold the active wells. No new wells show a 2024 or later spud date in the county's records.
Whatever you own here, producing royalties, non-producing acreage, or an inherited fraction split among family, we will identify it from whatever paperwork you have, value it off the actual wells and activity, and show you the reasoning with the offer. Free, no obligation, and no pressure: if keeping it is the right answer, we will say so. Inherited it? Start with inherited mineral rights in California.
