Fairfield, Rio Vista, Vacaville: we buy minerals and royalties throughout Solano County, the Rio Vista gas field, the largest dry gas field in California.
Solano County is the center of California's dry gas business, such as it is. The Rio Vista field has produced since 1936 and still does, the Montezuma Hills are dotted with small gas fields that most buyers have never looked at, and in 2026 the field's operator filed to drill more wells than this part of the state has seen in years. Gas royalties here are small, long-lived and finally worth paying attention to.
What produces here. CalGEM's 2023 annual report, the latest county table it has published, put Solano County at 1,019,017 Mcf of gas and 1,491 barrels of oil for the year. CalGEM's WellSTAR records as of November 2026 show 62 active wells: California Resources Production Corporation's 22 Rio Vista gas wells, Vesta Oil and Gas's 21 Lindsey Slough wells, Lodi Gas Storage's 17 Kirby Hill storage wells and Royale Energy's 2 Denverton Creek wells. In November 2026 CalGEM released a draft environmental study for California Resources' Rio Vista Well Development Project, 83 new natural gas wells in the Rio Vista field, 39 of them in Solano County, to tie into the existing gathering system.
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.
