Clayton, Des Moines, Folsom: we buy minerals and royalties throughout Union County, in the Bravo Dome CO2 field.
Union County is Clayton, the ranches around it, and the Bravo Dome CO2 unit underneath. The royalty checks here have come from carbon dioxide, not oil, since the 1980s, and they still arrive every month for families who have long since moved to Amarillo or Denver. Nobody mails them an honest number for it.
What produces here. Carbon dioxide from the Bravo Dome Tubb sandstone reservoir, with Oxy USA as the only operator in the county. MineralAnswers put Union at about 2 million Mcf for May 2026, second only to Harding among the non-Permian gas counties. The Des Moines CO2 field in the northwest of the county is inactive. Production peaked at 110.9 Bcf in 1996 and was 29.5 Bcf in 2022.
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. Send a Kinder Morgan or Oxy check stub and we will read the unit and the contract behind it. Inherited it?

The same Permian Tubb reservoir as Harding County, 98 to 99 percent carbon dioxide, piped to Permian oil floods.
A separate CO2 accumulation in the northwest of the county, currently inactive.
