Campbell County Produces Oil, Gas and Coal From the Same Basin
Campbell County produced about 24.1 million barrels of oil in 2025, nearly 23% of Wyoming’s total and second only to Converse County, and it ranked third in the state for gas at about 136 billion cubic feet. The oil comes from several formations: the Niobrara (about 8.8 million barrels in 2025), the Parkman, the Turner, the Mowry and the older Minnelusa fields, and the Mowry was the county’s largest gas source.
The county is also the center of American coal production. Its 11 surface mines produced about 170 million tons in 2024, roughly a third of the U.S. total according to the U.S. Energy Information Administration, including North Antelope Rochelle and Black Thunder, the country’s two largest mines. Coalbed methane drilling, which peaked across the Powder River Basin in 2009, followed those seams, and Campbell County’s coalbed methane wells still produced about 12.4 billion cubic feet in 2025 from 1,183 wells, with Carbon Creek Energy and Pronghorn the largest operators of record.
That history shows up in title. In a county where coal, coalbed methane and deeper oil and gas have all been developed, older deeds and leases sometimes treat them differently, so the first question on a Campbell County interest is exactly what your family owns: the oil and gas, the coal, or both, and at what depths.
The horizontal oil activity continues. Commission records for 2026 list EOG, Anschutz, Ballard, EMEP II, Peak Powder River and Devon among the county’s operators. Like Converse County to the south, Campbell can be developed in more than one formation under the same section, so a tract with older wells may still carry undrilled zones.
What We Check on a Campbell County Interest
- The deed language, to confirm whether the interest covers oil and gas, coal or both, recorded with the Campbell County Clerk in Gillette.
- Which formations the unit wells produce from, and which zones remain undrilled.
- Any coalbed methane wells on the tract and what they still pay.
- Pooling orders and federal tracts in each spacing unit.
- Lease royalty, deduction language and depth limits.
- Your decimal, the current operator and any royalty held in suspense.
Where Campbell County Mineral Records Are Kept
The Campbell County Clerk at 500 South Gillette Avenue, Suite 1600, in Gillette records deeds, leases and assignments. Well files, production by formation and pooling orders are held by the Wyoming Oil and Gas Conservation Commission in Casper; coalbed methane wells appear in the same Commission records as conventional and horizontal wells.
Campbell County, Wyoming Mineral Rights FAQs
Can I sell my oil and gas rights in Campbell County, Wyoming?
Yes. Whether you want to sell your oil rights, sell your gas rights, or sell your oil and gas royalty rights together, in Campbell County they are all mineral or royalty interests, and we buy them for cash. That includes the full mineral estate, overriding royalties, unleased acreage and fractional shares inherited from family. If your deed or lease covers only certain depths or formations, we value exactly what you own.
How much are my mineral rights worth in Campbell County?
It depends on the formations producing under your tract, the age of the wells, what is still undrilled, and your lease and decimal. A royalty in a new horizontal Niobrara or Parkman unit is valued very differently from an old coalbed methane royalty, so a recent statement is the best starting point.
Our deed mentions coal. Do we own the oil and gas too?
It depends on the exact words of the reservation or conveyance. Some Campbell County instruments separate coal from oil and gas, and some cover all minerals together. We read the recorded documents before valuing anything, and we tell you plainly what you own.
Are old coalbed methane royalties still worth anything?
Some are. Campbell County coalbed methane wells still produced about 12.4 billion cubic feet in 2025, but individual wells are often small and old. We value what the well is actually paying and tell you honestly whether it is worth selling on its own.
Do we need Wyoming probate to sell an inherited Campbell County interest?
Usually some Wyoming proceeding is needed to put the minerals in the heirs’ names. For an estate already probated in another state, Wyoming offers a short-form ancillary probate when the Wyoming property is worth $400,000 or less, and smaller estates can use a summary procedure that expressly covers mineral interests.
Can one heir sell without the others agreeing?
Yes. Co-owners hold undivided interests and each may sell their own share. We regularly buy one heir’s fraction without requiring the whole family to sell.
