Inherited Mineral Rights in Crook County, Wyoming
If you inherited mineral rights in Crook County, Wyoming, you likely own a portion of the subsurface estate on the eastern edge of the Powder River Basin, near the Wyoming-South Dakota border. Crook County has a long history of oil and gas production, with over 1,000 wells drilled since the late 1970s. Many families in this county hold small inherited mineral rights that have been passed down for generations without ever being formally transferred. This page explains how to confirm what you own, how minerals are valued here, and what your options are as a mineral owner.
Crook County sits along the eastern margin of the Powder River Basin, where conventional oil production has a deep history and where some formations continue to see periodic activity.
What Are Inherited Mineral Rights in Crook County?
Inherited mineral rights in Crook County represent ownership of subsurface resources that were separated from surface ownership and passed down through an estate.
Common components include:
Oil and natural gas interests in conventional formations
Rights to lease minerals to an energy operator
Rights to receive royalty payments if wells produce
The ability to participate in future leasing or development
Mineral rights are separate from the surface. You may own minerals without owning the surface land, and many owners discover this through royalty checks, paperwork, or unsolicited offers.
Why Crook County Is Unique for Mineral Owners
Crook County is part of the Powder River Basin, one of the most important energy basins in the western United States.
Key characteristics:
Located on the eastern edge of the basin, bordering the Black Hills of South Dakota
Long history of conventional vertical oil well production dating back decades
Less active than Campbell or Converse counties for current horizontal drilling, but still produces oil
Over 1,000 wells drilled in the county since 1978
Significant coal resources in the area, though coalbed methane activity has been limited compared to central basin counties
Mineral ownership is often highly fragmented due to generational inheritance on ranch and agricultural land
Major formations in the area include:
Muddy Sandstone
Shannon
Frontier
Minnelusa
Niobrara
Newcastle
Operators active in the broader basin have included:
EOG Resources
Devon Energy
Continental Resources
Various smaller private and regional operators
Because conventional production in Crook County has been more sporadic and spread over many years, many inherited mineral rights remain small, undeveloped, or loosely tracked by their owners.
How to Confirm What You Own in Crook County
Before making any decisions, it is critical to confirm exactly what you inherited.
Step 1: Gather documents
Collect estate paperwork, deeds, wills, or probate records that mention mineral interests.
Step 2: Check county records
Visit the Crook County Clerk and Recorder to locate recorded deeds, legal descriptions, and mineral separations.
Step 3: Identify the legal description
Note township, range, and section for each parcel or mineral tract.
Step 4: Clarify interest type
Determine whether the interest is a mineral fee title, royalty interest, or overriding royalty interest.
Step 5: Review spacing and pooling orders
Check whether your land is included in active or past spacing units. Contact the Wyoming Oil and Gas Conservation Commission (WOGCC) for details.
Being thorough at this stage prevents confusion later and ensures you know what rights and interests you actually hold.
Do You Need Probate to Sell Mineral Rights in Crook County?
In most cases, yes.
Wyoming buyers will require a clear title before completing a purchase. If the prior owner passed away and the minerals were not properly recorded in your name, buyers typically ask for probate or an affidavit of heirship to establish legal ownership.
Probate helps:
Establish a clear chain of title
Protect buyer and seller from future disputes
Ensure payments go to the correct heirs
Even if you are receiving royalty checks, probate may still be required before a sale is completed.
How Mineral Rights Are Valued in Crook County
Mineral rights in Crook County are valued based on several county-specific factors:
Whether the minerals are producing or non-producing
Proximity to active wells or areas of recent drilling interest
Targeted formations and depth of potential production zones
Operator presence and lease activity in nearby acreage
Net mineral interest size and royalty rate
Lease status and remaining terms
Potential for future development based on basin-wide trends
While Crook County is not among the most heavily drilled areas of the basin today, inherited mineral rights here can still carry value — particularly if located near formations that are targets elsewhere in the Powder River Basin.
