If you own mineral rights in Wyoming's Powder River Basin, you're sitting on one of the most actively drilled regions in the entire country. Whether you inherited these rights from a parent or grandparent, or picked them up along the way, understanding what you actually own — and what it's worth right now — matters more than most people realize.
This guide will walk you through the geology that drives value in the PRB, what's happening in Campbell County today, who the major operators are, how federal mineral ownership affects your situation, what your rights are likely worth in the current market, and what to expect if you decide to explore selling. By the end, you'll have enough real information to make a confident decision — whether that's selling, holding, or just knowing more than you did yesterday.
You don't need to be a geologist or a landman to understand this. You just need someone to explain it straight.
What Makes Powder River Basin Minerals Valuable Right Now
The Powder River Basin sits in northeastern Wyoming and stretches slightly into southeastern Montana. It covers roughly 19,000 square miles and has been producing oil and gas in one form or another since the 1950s. What's changed dramatically in the last decade is how companies drill there — and that change has made certain mineral rights significantly more valuable.
For most of the PRB's history, drillers targeted shallow coalbed methane (natural gas trapped in coal seams) and conventional oil zones. Those plays are largely mature now. The action today is in deeper, unconventional tight oil — meaning crude oil locked in dense rock that requires horizontal drilling and hydraulic fracturing (commonly called fracking) to produce economically.
Three formations drive most of that activity:
The Turner Sand is currently the hottest play in the basin. It sits roughly 8,000 to 10,000 feet below the surface in parts of Campbell and Converse Counties, and operators are landing horizontal wells there that can produce 500 to over 1,000 barrels of oil per day in their first month. That's a strong well by any measure. EOG Resources, one of the best operators in the country at finding high-quality rock, has staked a major position here.
The Niobrara Formation is a chalk and shale unit that sits above the Turner, typically between 6,500 and 8,500 feet deep in the PRB. It's been producing across a wide swath of Wyoming and Colorado for years. In the PRB, the Niobrara is often stacked directly above the Turner, meaning a single surface location can access multiple pay zones — which increases the value of the mineral acres underneath.
The Mowry Shale is deeper and less developed than either the Turner or Niobrara, but several operators have been quietly testing it. It hasn't reached full commercial development yet in most of the PRB, but it's a real option that adds optionality value to mineral acres in the right areas. Think of it as a bonus layer beneath what's already being drilled.
If your minerals sit in or near Campbell County — particularly in the areas around Gillette, Wright, or Recluse — there's a real chance one or more of these formations runs beneath your land. That's what drives value.
Campbell County: The Core of PRB Activity
Campbell County is the epicenter of Powder River Basin oil development. The county seat is Gillette, Wyoming, which has been an energy town for decades. In terms of rig activity and new well permits, Campbell County consistently ranks among the top counties in Wyoming, and often in the top tier nationally for unconventional oil.
As of 2024, the Wyoming Oil and Gas Conservation Commission (WOGCC) — the state agency that tracks drilling activity — shows dozens of active drilling permits in Campbell County alone, with EOG Resources, Civitas Resources (which absorbed several legacy PRB operators), and Devon Energy among the most active. These are billion-dollar companies with long-term development plans in the basin, not speculators drilling one well and walking away.
What that means for mineral owners is real: if your acreage is in a productive part of Campbell County, you are not waiting for development to happen someday. Development is happening now, or it's already happened on adjacent sections.
A section is a standard land measurement used in oil and gas — one square mile, or 640 acres. Mineral rights are often described in terms of net mineral acres (NMAs), which is your proportional ownership of the minerals under a given tract. If your family owned the minerals under 160 surface acres (a quarter section), and you own half of that mineral interest, you own 80 net mineral acres.
In highly productive parts of Campbell County, net mineral acres in proven Turner Sand territory have been trading in the range of $3,000 to $7,000 per net mineral acre in recent transactions. That's a wide range because location matters enormously — acreage directly offset (adjacent) to producing wells commands a premium, while acreage further from current development trades lower. If your minerals are already producing royalty income, valuations shift to a multiple of that income, typically 4 to 6 times annual royalty.
These are real market numbers, not promotional estimates. They reflect actual transactions, and they move with oil prices and basin activity.
Federal Minerals vs. State and Fee Minerals: Why This Matters to You
This is one area where Wyoming mineral owners get tripped up, and it's worth slowing down to explain clearly.
In Wyoming — and across much of the American West — the federal government owns a significant portion of the mineral rights beneath privately owned surface land. This is a legacy of how the West was settled. When the federal government granted homestead or railroad land patents in the 1800s and early 1900s, it sometimes reserved the minerals for itself. That means today, the surface might be a private ranch, but the oil and gas below it belong to the United States and are managed by the Bureau of Land Management (BLM).
If your mineral rights are federal minerals, you don't own them — the federal government does. What you might own instead is a royalty interest from a federal lease, which is different. Federal lessees (the oil companies) pay a royalty — currently 16.67% under most modern federal leases — directly to the federal government, which then splits a portion (typically 49%) with the state of Wyoming. Private landowners in this situation often receive nothing directly unless they negotiated a surface damage agreement.
Contrast that with fee minerals (also called private minerals), where you hold actual title to the oil and gas in the ground. Fee mineral owners negotiate directly with oil companies and receive lease bonuses and royalties without federal or state intermediaries.
And then there are state minerals, which Wyoming owns in substantial quantities, particularly around school trust lands. These are managed by the Office of State Lands and Investments.
Why does this matter to you? Because if someone approaches you wanting to buy your "mineral rights" and you actually only have a surface interest with no mineral ownership, there's nothing to sell. Conversely, if you genuinely own fee minerals, you may be holding something worth real money.
To figure out what you own, start with the deed or probate documents that transferred the interest to you. If those documents say something like "together with all oil, gas, and mineral rights appurtenant thereto," that's a good sign you own the minerals. If you're unsure, a title company or oil and gas attorney in Wyoming can run a title search for a few hundred dollars. It's worth doing before you do anything else.
How Wyoming Taxes Mineral Rights Sales and Royalty Income
Wyoming is unusually friendly to mineral owners from a tax standpoint, and this is one concrete financial advantage worth understanding before you make any decisions.
Wyoming has no state income tax. Zero. That means royalty income you receive from oil and gas production is taxed only at the federal level. For most people in their 50s through 70s, federal ordinary income tax rates on royalties typically run between 22% and 32%, depending on your total income. Royalties are treated as ordinary income by the IRS, not capital gains — so you can't get the preferential 15% or 20% long-term capital gains rate on royalty payments.
However, if you sell your mineral rights, the proceeds are generally treated as a capital gain (assuming you've held the property for more than a year). Long-term capital gains rates for most sellers in this income range are 15%, and Wyoming takes nothing on top of that. Compare that to states like California (up to 13.3% state tax on top of federal) or Colorado (4.4%) — Wyoming mineral sellers keep meaningfully more of what they receive.
There's one more tax consideration: Wyoming does levy a severance tax on oil and gas production — 6% for oil and natural gas. This is typically deducted from your royalty check before it reaches you, so you're already receiving the net amount. It's not an additional burden on you personally, but it's worth understanding why your royalty check doesn't reflect the full wellhead price.
If you're considering a sale, talk to a CPA before you close. Specifically ask about your cost basis in the minerals — what you paid for them (or what they were valued at when you inherited them). A higher basis reduces your taxable gain. If you inherited these rights from a parent who passed away after 2010, you likely received a stepped-up basis to the fair market value at the time of death, which can meaningfully reduce your tax bill.
What Your PRB Minerals Are Worth: Realistic Valuations
Let's be direct: mineral rights are not publicly traded, there's no Zillow for them, and anyone who gives you an instant online valuation without reviewing your actual documents is guessing. That said, there are real frameworks buyers use, and you should understand them.
If your minerals are currently producing royalties, buyers look at your trailing 12-month royalty income and apply a multiple. In the PRB today, that multiple for producing minerals is typically in the range of 48 to 72 months of royalty income — meaning 4 to 6 times annual royalties. If you're receiving $12,000 per year in royalties from Turner Sand production in Campbell County, a realistic offer range might be $48,000 to $72,000. Premium buyers for high-quality, long-lived production may go higher.
If your minerals are not currently producing but are in an area with active development, buyers use comparable sales and geological data to estimate value. Acreage in the proven core of the PRB Turner play — in sections with offsetting production or active permits — might attract $3,000 to $6,000 per net mineral acre or more. If you own 80 net mineral acres in a prime Campbell County section, that's a realistic range of $240,000 to $480,000. This is why knowing precisely what you own matters so much.
If your minerals are in the basin but far from current development, values drop substantially — sometimes to a few hundred dollars per acre — because buyers are paying for optionality with no guarantee of when or whether a well gets drilled.
Oil prices obviously move these numbers. WTI crude oil (the U.S. benchmark price) has ranged roughly from $70 to $90 per barrel through most of 2023 and 2024. At these prices, PRB operators are actively drilling and the economics work. If oil dropped to $50 and stayed there, development would slow and valuations would compress. The reverse is also true.
One practical step: if you're receiving royalty checks, pull out the last three to four check stubs and add up what you received in the last 12 months. That number is your baseline. A legitimate buyer will want to review those documents and your division order (the document that establishes your ownership percentage) before making a formal offer.
The PRB Market Outlook: What Experienced Buyers Are Seeing
The Powder River Basin is not a flash-in-the-pan play. EOG Resources — arguably the best unconventional oil operator in the United States — has said publicly that the PRB Turner Sand is one of its top three or four plays nationwide. That is a meaningful endorsement. When a company like EOG, which is disciplined about capital allocation, makes that statement and backs it up with hundreds of millions in drilling budgets, it signals long-term confidence in the basin.
Several factors support continued activity in the PRB over the next several years:
First, Wyoming's regulatory environment is relatively operator-friendly compared to Colorado or California. Permitting timelines are reasonable, and there's no moratorium on new drilling. The state's economy depends substantially on oil and gas revenue, which creates a political incentive to keep things moving.
Second, the stacked pay opportunity — Turner, Niobrara, Mowry, and other zones — means operators who already have infrastructure in a given area have multiple targets to drill without moving. This is efficient, and it extends the life of development programs.
Third, the basin's takeaway capacity (pipelines to move oil out of Wyoming) has improved. Crude oil from the PRB can flow to Cushing, Oklahoma and to refineries in multiple directions, reducing the discounts Wyoming operators used to face compared to WTI benchmark prices.
The honest caveat here: no one can tell you with certainty what oil prices will be in three years, and no one should. What experienced market observers can say is that the PRB has the geology, the operators, and the infrastructure to remain an active basin at oil prices the current market considers base case — roughly $65 to $80 per barrel. The minerals under productive Campbell County acreage are not going to be worthless.
For mineral owners weighing whether to sell now or hold, the core question is personal, not just financial: Do you need or want liquidity today? Are you worried about oil price volatility eroding future royalties? Do you have heirs who will benefit from a clean, simplified estate? Or do you want to keep receiving quarterly checks and maintain your ownership position? None of these answers are wrong. They just reflect different priorities.
