Campbell County is Powder River Basin Niobrara play acreage, in the core of the Powder River Basin around Gillette. The producing rock under Campbell County includes the Niobrara, Big George coal, and Minnelusa, giving owners a royalty check drawn from both oil and gas. Carbon Creek Energy LLC, EOG Resources INC, and High Plains Gas LLC are among the operators on record here. The most recent drilling on record was spudded in 2022. Owners in Campbell County often sell to capture value while operators are active, to settle an estate, or because they would rather hold cash than manage a fractional interest from out of state.

Campbell County oil and gas activity

Public state commission records show 18,276 active oil and gas wells in Campbell County . The most recent drilling on record was spudded in 2022. That is the largest active-well count of any county we cover in Wyoming. These figures are pulled from the state oil and gas commission and are an activity snapshot, not a measure of any one owner's interest.

Producing formations in Campbell County

The formations and pools that actually produce in Campbell County, from the well records:

• Niobrara
• Big George coal
• Minnelusa

Producing interests in the Powder River Basin Niobrara play are valued on the standard income multiple, roughly 36 to 72 times the average monthly royalty check, and the heavy, active development here can support the upper part of the band where wells are strong. Because production is a mix of oil and gas, value moves with both oil and gas prices. This is an estimate, subject to verification, not an offer.

How Campbell County 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. Where you land inside that band depends mostly on how fast your wells decline, plus the operator, royalty rate, and any undeveloped drilling upside.

Who buys mineral rights in Campbell County

Campbell County owners hear from brokers, marketplaces, and direct buyers. A broker lists your interest and takes a commission, usually up to 6 percent of your proceeds. Ironwood Royalty is a principal buyer, which means the offer comes from us and there is no commission in the middle. We show you a value range before we ask for anything, explain the undeveloped upside instead of quietly keeping it, and never use a 72-hour deadline to rush a decision on a generational asset.

How to sell Campbell County minerals

The order of operations is the same everywhere, and it protects you:

• Know your value range before you talk to any buyer.
• Ask every buyer to quote per net royalty acre so offers are truly comparable.
• Ask directly whether the offer accounts for undeveloped drilling upside.
• Confirm the price is firm and not subject to a quiet reduction during due diligence.

Campbell County is part of the Powder River Basin. For the basin-wide value bands and the other counties we buy in, see the Powder River Basin page.

Campbell County mineral rights questions

How much are Campbell County mineral rights worth?

Producing Campbell County royalties are valued at roughly 36 to 72 times your average monthly royalty check. Because the county is heavily drilled, interests with strong wells and undeveloped upside can price toward the higher end. This is an estimate, not an offer.

What formations produce in Campbell County?

Campbell County produces from the Niobrara, Big George coal, and Minnelusa, which is why a single tract can sometimes be paid from more than one zone. Stacked pay can lift the total value even when each interest looks small. Your value still follows the same income multiple applied to your actual check.

How active is drilling in Campbell County?

State commission records show about 18,276 active oil and gas wells in Campbell County, with operators including Carbon Creek Energy LLC, EOG Resources INC, and High Plains Gas LLC. We name operators because the record is public; this is not an endorsement. The activity is a county snapshot, not a measure of any one owner's interest.
