San Luis Obispo, Arroyo Grande, Paso Robles: we buy minerals and royalties throughout San Luis Obispo County, the Arroyo Grande heavy oil field.
San Luis Obispo County is one oil field and a lot of wine country. Arroyo Grande, up Price Canyon from Pismo Beach, is a heavy oil field that has been steamed for decades and still produces more than half a million barrels a year, and nearly all of the county's royalty income comes from it. The rest of the county's minerals, from Paso Robles to the Carrizo Plain, are non-producing and mostly stay that way.
What produces here. CalGEM's 2023 annual report, the latest county table it has published, put San Luis Obispo County at 575,504 barrels of oil and 405,923 Mcf of associated gas for the year. CalGEM's WellSTAR records as of November 2026 show 270 active wells, 250 of them Sentinel Peak Resources California wells in the Arroyo Grande field, with E and B Natural Resources operating 11 in Russell Ranch and Chevron 9 in the county's corner of Midway-Sunset; another 28 wells carry a New status in the records. Sentinel Peak, a Denver-based heavy oil company formed in 2016 by former Berry Petroleum managers, runs Arroyo Grande on steam, with landfill gas displacing some of the natural gas burned for steam generation.
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.
