Sweetwater County Is Wyoming’s Second-Largest Gas County
Sweetwater County reported about 212 billion cubic feet of gas in 2025, about 16% of Wyoming’s total and second only to Sublette County, along with about 3.2 million barrels of oil. Its gas comes from the Almond, Mesaverde and Lewis formations of the greater Green River Basin, and Commission records for 2026 list Crowheart Energy, owned by Williams since 2024, at Siberia Ridge, Echo Springs and Wamsutter, Contango Resources at Patrick Draw, and Wexpro, now owned by Enbridge, and Hilcorp among the county’s operators.
Title here starts with the railroad. The Union Pacific Act of 1862 granted the railroad the odd-numbered sections for up to 20 miles on either side of the track, and the government kept the even sections, creating the checkerboard that still runs across southern Wyoming. The land-grant minerals passed from Union Pacific to Anadarko and then Occidental, which sold a package of about 4.5 million mineral acres in 2020, so who holds the oil and gas rights in a particular section has to be traced from the record. One section can belong to a private family, the next to the federal government, and the one after that to a land-grant successor, and a spacing unit can combine all three.
The next phase of gas development was approved in 2016, when the Bureau of Land Management signed off on the Continental Divide–Creston project: about 8,950 wells over roughly 1.1 million acres west of Rawlins and east of Rock Springs, infilling the Wamsutter and Creston areas over a 30- to 40-year life. Approval is permission, not a drilling schedule, so the pace depends on operators and gas prices.
Sweetwater also has oil fields that work differently. The Lost Soldier field near Bairoil is a carbon dioxide flood, where CO2 and water are injected to push more oil out of an old reservoir, so its royalties come from enhanced recovery rather than new wells.
What We Check on a Sweetwater County Interest
- Whether the tract lies in the checkerboard, and whether its section came through private, federal or railroad land-grant title.
- Chain of title in the Sweetwater County Clerk’s records in Green River.
- Federal and land-grant tracts in the spacing unit, and any communitization agreement.
- The field and formation behind each well, and how far the wells have declined.
- Deductions measured against the Royalty Payment Act, especially gathering and compression.
- Your decimal, the current operator, and any royalty held in escrow.
Where Sweetwater County Mineral Records Are Kept
The Sweetwater County Clerk at 80 West Flaming Gorge Way in Green River records deeds, leases and assignments. Well and production records are held by the Wyoming Oil and Gas Conservation Commission in Casper, and federal leases and communitization agreements by the Bureau of Land Management. In the checkerboard, the county record shows the private and land-grant chain, while the federal sections are traced through federal records.
Sweetwater County, Wyoming Mineral Rights FAQs
Can I sell my oil and gas rights in Sweetwater 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 Sweetwater 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 Sweetwater County?
It depends on the wells under your tract, how far they have declined, gas prices, deductions, and your share of each unit, including how much of the unit is federal or land-grant acreage. Undeveloped acreage in the Continental Divide–Creston area is valued on the likelihood and timing of new wells. A recent statement or legal description is enough to start.
Our land is in the checkerboard. Does that affect the minerals?
Often. Ownership can change from one section to the next, and land-grant minerals passed from Union Pacific to Anadarko and then Occidental, which sold a large mineral package in 2020. We trace the actual chain for your section before valuing it, because a unit’s royalty is shared among all of its owners.
Does the Continental Divide–Creston approval mean wells will be drilled on our land?
Not necessarily. The 2016 approval allows up to about 8,950 wells over decades, but each well still needs an operator to decide to drill it. Its effect on value is that it makes development possible across a wide area, not that it guarantees any particular location.
What does a CO2 flood mean for an oil royalty?
In a carbon dioxide flood such as Lost Soldier, CO2 and water are injected into an old reservoir to recover more oil. The royalty depends on the flood’s performance and the oil price rather than on new drilling, and it can run for many years at a steady but modest rate.
Can we sell gas royalties that are years past their peak?
Yes. Many Sweetwater County gas wells are mature, and buyers value the remaining production over the wells’ lives. Owners often sell older royalties to settle an estate or simplify their holdings, and we will tell you honestly whether yours is worth selling.
