Mineral Rights Value Calculator
Describe the property, county and state, interest type, net acres if known, producing status, recent revenue, and the calculation question.
Montana mineral owners sit on two very different plays, and the calculator treats them differently on purpose.
Run a Montana address through our calculator and the first question it asks is which side of the state you're on. Northeastern Montana - Richland, Roosevelt, and Sheridan counties - is the western edge of the Williston Basin, the same Bakken/Three Forks trend that made North Dakota famous, just thinner and less drilled on this side of the line. Southeastern Montana, centered on Powder River and Custer counties, is a different animal: an older coalbed-methane and conventional oil basin with a much longer, slower production history.
Those two geologies produce two different value stories, and lumping them together is how sellers end up either underpricing a good Bakken-edge tract or overpaying attention to a stripper well that's been declining since the Clinton administration.
Sidney, the Richland County seat, sits close enough to the North Dakota border that some sections have real horizontal Bakken wells on them, operated by names familiar from the Williston side - Continental, Kraken, and a handful of smaller operators picking up acreage divested by the majors. If your minerals are under or near an active horizontal unit, our tool asks for your net royalty checks over the trailing months and works from there, because a real check beats a basin average every time.
Move south into Powder River County, seat Broadus, and the story changes. Wells here are often decades old, producing modest conventional oil or coalbed gas at low, steadily declining volumes. There's still value - buyers exist for long-lived stripper production because the decline curve has already flattened out - but the multiple applied to a flat, mature stream looks nothing like the multiple applied to a two-year-old horizontal well still climbing down its steep early decline.
For a producing tract, we ask for your net mineral acres, your decimal interest as shown on the check stub or division order, and either the last several royalty payments or the well's reported production if you don't have statements handy. For undeveloped acreage - common in the Powder River flank counties where nothing has been drilled on your specific section in years - the calculator falls back to comparable lease bonus and recent county-level sale data, which produces a wider, more honestly hedged range.
One Montana-specific wrinkle worth entering correctly: severed mineral ownership here often traces back to homestead-era patents that reserved minerals to the railroad or the federal government, which means your family may own less of the section than deed records first suggest. Pull your actual mineral deed before you trust any number, ours included.
Whatever range the calculator returns, treat it as a starting point for negotiation, not a quote you can bank. Values in the Bakken-edge counties move with rig counts that can shift in a matter of months, and values in the Powder River counties move with commodity prices acting on wells that are, by nature, running out. If a buyer offers well above our range with no explanation, ask what they know about your unit that you don't - sometimes that's a real answer, like a permitted offset well, and it's worth finding out before you sign anything.
We're a mineral buyer, not a licensed appraiser, and this tool is meant to sharpen your own homework, not replace a title check or a conversation with someone who has actually seen your division order.
Keep an eye on operator activity reports filed with the Montana Board of Oil and Gas Conservation, too. A permit filed near your section, even before a well is spudded, is often the earliest real signal that value in your area is about to move, well ahead of any calculator update.
