Cortez, Dolores, Mancos: we buy minerals and royalties throughout Montezuma County, the McElmo Dome CO2 field and the Paradox Basin.
Montezuma County is the largest gas-producing county in Colorado by volume and almost none of it is natural gas. McElmo Dome produces carbon dioxide, more than 18 billion cubic feet a month, piped south to the Permian to push oil out of old fields. The royalties under Cortez are CO2 royalties, with decades of history and a decline curve that has nothing to do with Henry Hub.
What produces here. Carbon dioxide from the McElmo Dome Leadville Limestone reservoir, operated by Kinder Morgan CO2 Co LP, plus small Paradox Basin oil producers. The county reported 18.5 Bcf from 84 producing wells and 5 operators in June 2026, including Kinder Morgan, Seeley Oil, Rim Operating and Bayless. MineralAnswers put the county at about 120,900 barrels of oil equivalent a day in April 2026, the highest of any Colorado county not yet on this site, nearly all of it CO2. More than half the county's tax revenue comes from the field.
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 check stub and we will read the unit and the contract behind it. Inherited it?
