Sell Mineral Rights in Natrona County, WY
Casper is the county seat, and Natrona County has been oil country since before Wyoming was a state. If you hold minerals here, there is almost always a record of them at the courthouse.
Natrona County sits where the old Salt Creek field runs into the southern edge of the Powder River Basin, with the North Platte River cutting the county in half on its way past Casper. This is some of the oldest production in the Rocky Mountains. Salt Creek was drilled before 1910 and is still pumping stripper wells today, mostly shallow Wall Creek and Frontier sand. North and east of Casper, operators have chased Niobrara and Turner Sand horizontals down toward the Converse County line, and some of those units reach back into Natrona.
What that means for a mineral owner is two very different kinds of interest can sit in the same county. Some families hold small legacy fractions under Salt Creek that have paid a modest, steady royalty for generations. Others hold flank acreage that only got interesting once horizontal rigs started walking north out of Converse. We work both kinds, and we do not treat a five-dollar-a-month legacy interest the same as an active unit — the file work is different and so is the offer.
Salt Creek legacy interests
A lot of what crosses our desk out of Natrona County traces back to Salt Creek allotments split up decades ago. Original 40s and 80s got carved into eighths and sixteenths as they passed through estates, and by now some owners have interests measured in the thousandths. The wells are old, mostly stripper production on artificial lift, and the decline curve flattened out a long time ago. That is not a knock on the interest — a flat, long-lived stripper royalty can be worth selling precisely because it is predictable, and predictable is what a buyer can price without guessing.
If your check comes from a Salt Creek unit, bring the most recent division order and a couple of check stubs when you call. That tells us the decimal interest and the operator faster than anything else you could send.
Where the Powder River Basin activity reaches in
The active drilling in this part of the state is concentrated in Converse County to the north, targeting the Niobrara and Turner formations in horizontal wells with long laterals and multi-well pads. Some spacing units for those wells cross the county line into northern Natrona, and owners here can end up pooled into a unit even without a rig ever sitting on their own tract. That is a different conversation from Salt Creek — it is about undeveloped or recently developed acreage with real upside tied to what an operator does next, not a settled stripper decline.
Split estate and the North Platte corridor
Along the North Platte River corridor and around Casper itself, a lot of surface has been subdivided for ranchettes and small acreages while the mineral estate stayed with the original ranching family or was severed off decades earlier at a land sale. That is a textbook split estate: whoever bought the house on five acres does not own what is under it. If you are the mineral owner in that situation, Natrona County's clerk records will usually show the severance deed, and that document is the first thing we pull before making an offer.
The county assessor and clerk's office in Casper keep good digital records going back further than most Wyoming counties, which speeds up title work on our end and usually speeds up your check.
What we look at before we make an offer
We start with your decimal interest, the unit or well it sits in, and recent production or royalty history if you have it. For Salt Creek and other legacy stripper interests, we weigh in the depth of the decline and how long that production has been stable. For flank acreage near the Converse County activity, we weigh in permitting activity and whether operators are actively leasing or drilling nearby. Either way, the number we quote is tied to what is actually happening on the ground, not a flat statewide rate — anyone who quotes you a number without asking what county and what formation is guessing.

Resolve the Record Question Before It Reaches the Deed
Often, yes. Small legacy fractions are exactly the kind of interest we buy — the value is in the reliability of the production, not the size of the check. We can review your decimal and recent history and give you a real number.
Natrona County's clerk of court keeps deed records that show severance, usually as part of an old sale or a mineral reservation clause. We can pull that record as part of our title review once you give us the legal description.
It matters a lot for pricing. Old vertical stripper wells have a known, flat decline. New horizontal units carry more upside but also more uncertainty until production history builds. We price each differently and tell you why.
A recent division order, a check stub or two, and the legal description if you have it. If you only have an old lease or a probate document, that works too — we can trace it from there.
We look at those case by case, weighted heavily on nearby activity and formation potential. Non-producing acreage near the active Powder River trend in Converse is a different conversation than an isolated non-producing tract with no nearby drilling.
