What are Montana mineral rights worth?
Montana holds the same Bakken and Three Forks geology as North Dakota on the northeast side of the Williston Basin, where Richland County's Elm Coulee field is the core of the Montana Bakken, alongside Roosevelt, Sheridan, Fallon, and Dawson counties. Conventional oil sits in the Bighorn Basin at Elk Basin and along the Sweetgrass Arch at Cut Bank and Kevin-Sunburst, with the northern edge of the Powder River Basin in the southeast. Producing royalties are valued on a multiple of income, roughly 36 to 72 times the average monthly check. The Montana Board of Oil and Gas Conservation regulates. Every figure is an estimate subject to verification of your specific interest.
Montana shares the Williston Basin and the Bakken with North Dakota, just on the western side of the line. The Montana Bakken is centered on the Elm Coulee field in Richland County, one of the early discoveries that proved the modern Bakken play, with horizontal Bakken and Three Forks development extending into Roosevelt, Sheridan, Fallon, and Dawson counties in the northeast. The rest of the state is more conventional: the Bighorn Basin in the south holds the Elk Basin field, the Sweetgrass Arch along the northern border produces oil at Cut Bank and the Kevin-Sunburst area, and the northern edge of the Powder River Basin reaches into the southeast. Montana is smaller-scale than North Dakota, but it is the same Bakken geology, and value follows the same logic. The Montana Board of Oil and Gas Conservation regulates drilling and spacing across the state.
How Montana minerals are valued
Producing interests anywhere are valued on a multiple of the income they pay: roughly 36 to 72 times your average monthly royalty check, the same as 3 to 6 times your annual royalty. Average your last three to six checks, then multiply. Montana value is led by the northeast Williston Basin, where the same Bakken and Three Forks geology as North Dakota supports oil production, with conventional fields in the Bighorn Basin and along the Sweetgrass Arch. Producing royalties are valued on the standard income multiple, roughly 36 to 72 times the average monthly check, with seasoned Bakken wells supporting steadier valuations. Montana is smaller-scale than North Dakota, and it uses common-law mineral title recorded at the county level, so confirming clean, recorded ownership of your specific tract is an important step before a sale.

What makes Montana different
- The Montana Bakken at Elm Coulee: Richland County's Elm Coulee field is the core of the Montana Bakken, with horizontal Bakken and Three Forks development extending into Roosevelt, Sheridan, Fallon, and Dawson counties.
- Conventional oil to the south and north: The Bighorn Basin holds the Elk Basin field and the Sweetgrass Arch produces oil at Cut Bank and Kevin-Sunburst, adding steady conventional production away from the Williston Basin.
- Same Bakken geology, smaller scale: Montana shares North Dakota's Bakken and Three Forks geology on the western side of the Williston Basin, but at a smaller overall scale, so value leans on existing production.
- Common-law title and state regulation: Montana holds mineral title under common law recorded at the county level, and the Board of Oil and Gas Conservation regulates drilling, so confirming clean title is part of a sale.
Basins and counties we buy in Montana
Mineral value is local. Choose your basin, then your county or parish, for the local value context and the questions owners there ask most.
Williston Basin
The Williston Basin of western North Dakota is home to the Bakken and Three Forks, the play that launched the American shale-oil era. McKenzie, Williams, Mountrail, and Dunn counties form the core, with Divide on the northern edge. The field is mature: North Dakota crude production runs around 1.1 million barrels a day and has been easing as the basin's best locations get drilled and wells move past their steep first-year decline. For mineral owners that maturity cuts two ways. Many Bakken wells have produced long enough to settle into a flatter, more predictable decline, which can support a steadier valuation, but there is less undeveloped drilling upside left than in the Permian. North Dakota also carries the strongest owner-search demand of any basin outside Oklahoma, so owners here actively look up what their royalties are worth.
Bighorn Basin
The Bighorn Basin spans northwest Wyoming and reaches into south-central Montana. On the Wyoming side it covers Park, Hot Springs, Big Horn, and Washakie counties, and on the Montana side Carbon and Big Horn counties, including the long-producing Elk Basin field that straddles the state line. It is primarily a conventional oil basin, with production from formations such as the Tensleep Sandstone, the Phosphoria, and the deep Madison Limestone, often trapped in large surface anticlines that made the basin an early target in the history of Rocky Mountain oil. Many of these fields have produced for a very long time and are now mature, with much of their output supported by secondary recovery like waterflooding. The basin is oil-weighted and well past its peak, so for mineral owners it generally means seasoned producing conventional oil interests with long, slow declines rather than a frontier of new horizontal drilling.
Sweetgrass Arch
The Sweetgrass Arch is a broad north-trending uplift in north-central Montana, running up to the disturbed belt along the Rocky Mountain Front in Glacier and Toole counties. It is a long-running conventional oil province, not a shale play. Its production comes from the Cut Bank field and the Kevin-Sunburst field, which draw oil from the Cretaceous Cut Bank Sandstone, the Sunburst sand, and the Mississippian Madison carbonates. These fields were discovered in the 1920s and 1930s and have produced for the better part of a century. Today the area is deeply mature and stripper-heavy, with most wells yielding small steady volumes from reservoirs that have been on production for decades. For mineral owners the value here is oil-weighted and rests on existing production rather than new drilling, since the structures were mapped and developed generations ago and undeveloped upside is limited. The long, slow decline of these conventional reservoirs can still support a steady valuation.
Powder River Basin
The Powder River Basin covers northeast Wyoming, including Campbell, Converse, Johnson, and Sheridan counties, and extends north into southeast Montana. It carries two very different oil and gas stories. The first is a modern tight-oil play, where operators drill horizontal wells into stacked targets like the Niobrara, Frontier, Mowry, and the Shannon and Sussex sandstones, concentrated in Converse and Campbell counties. The second is the basin's legacy coalbed methane gas, produced from the Fort Union coals including the thick Wyodak and Big George seams, which drove a large boom in the 1990s and 2000s and has since faded sharply with low gas prices. So the basin is genuinely mixed: an active oil-weighted core alongside a mature, largely depleted gas province. Operators on the oil side have included EOG Resources, Devon Energy, Continental Resources, Anschutz, and Chesapeake. For mineral owners, what an interest is worth here depends heavily on which of these two stories your acreage falls into.
Why owners in Montana sell
Most owners who sell are not in distress. They want certainty instead of a check that rises and falls with commodity prices and well decline, they are settling an estate among several heirs, or they live far from the basin and would rather hold cash than manage a fractional interest. Selling trades future income for a sum now, and the right answer depends entirely on your situation. We will tell you honestly when holding is the better move.
How to sell Montana minerals the right way
Know your range before you talk to any buyer, ask every buyer to quote per net royalty acre so offers are comparable, and ask directly whether the offer accounts for undeveloped drilling upside.

Montana mineral rights questions
- How much are Montana mineral rights worth?
- Producing Montana minerals are valued on a multiple of your royalty income, roughly 36 to 72 times the average monthly check. Seasoned Williston Basin Bakken wells can support steadier valuations, while conventional Bighorn and Sweetgrass Arch interests lean on long, steady production. This is an estimate, not an offer.
- Where can I sell mineral rights in Montana?
- Ironwood Royalty buys Montana mineral and royalty interests directly from owners as a principal buyer, across the Williston, Bighorn, Sweetgrass Arch, and Powder River areas, with no broker commission and an honest value range up front.
- Is the Montana Bakken the same as the North Dakota Bakken?
- It is the same geology, just on the Montana side of the Williston Basin. The Elm Coulee field in Richland County was one of the early discoveries that proved the modern Bakken play. Montana's development is smaller in scale than North Dakota's, so value leans on existing production, but a seasoned Bakken interest can support a solid valuation on the income multiple. Get an honest value range first, then decide.
