Colby, Brewster, Rexford: we buy minerals and royalties throughout Thomas County, Lansing-Kansas City and Marmaton oil that boomed in 2020 and is settling back.
Thomas County is Colby and a pile of small Lansing-Kansas City fields that drilled up fast around 2019 and 2020, when county production jumped from 354,280 barrels in 2018 to 563,904, and have been declining ever since. Nothing is wrong with that; it is what new wells in old rock do. It just means a Thomas County royalty has to be priced off its own decline curve, not off the headline year.
What produces here. Kansas Geological Survey production for 2025: 200,188 barrels of oil from 150 wells, and 104,936 barrels from 144 wells for January through June 2026; the county reported no gas in 2025. Oil spiked to 563,904 barrels in 2020 and has fallen every year since. It is Lansing-Kansas City, Marmaton and Cherokee oil from Towns, Ohl, U-Pac, Riverford, Campus North and Triangle among 126 active fields. Operators on checks and in the county records include Val Energy, Murfin Drilling, American Warrior, Gore Oil Company, Carmen Schmitt, Vess Oil, MAD Operators, Elevate Energy, Norstar Petroleum, DGH Oil, ELK Energy Holdings, BEREXCO and Mid-Continent Resources. The Kansas Corporation Commission lists Thomas in a 29-well District 4 orphan-well plugging project for the federal formula-grant round.
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 Kansas.
