in San Juan County,
Utah.
San Juan County is a different oil and gas story from the rest of Utah. The Paradox Basin underlies most of the county, and the Greater Aneth field has been producing since 1956. Modern interest is also turning to the Cane Creek shale in the northern Paradox. We are happy to help you understand what you have.
The Paradox Basin,
a different play entirely.
San Juan County in southeastern Utah sits in the Paradox Basin, an entirely different geologic setting from the Uinta Basin to the north. The Paradox is named for the Pennsylvanian-age Paradox Formation, a thick package of marine carbonates and evaporites that sourced and trapped substantial quantities of oil and gas across southeastern Utah, southwestern Colorado, and northern Arizona.
The Texas Company drilled the Aneth discovery well in 1956, hitting 1,704 barrels per day from the Paradox Formation. Greater Aneth field has produced over 479 million barrels of oil and remains an active waterflood and CO2 flood operation today. Beyond Aneth, more than 100 smaller fields have been discovered across the Paradox, and the Cane Creek shale in the northern part of the basin is an emerging horizontal target.
If you are reading this, you may be thinking about an interest that has been generating royalty income for decades, an inherited fractional interest, or minerals on or adjacent to Navajo Nation land. This page walks through the rock, the operators, the geography, valuation, and the regulatory landscape including the substantial tribal overlap that makes San Juan County unlike anywhere else in Utah.

The Paradox Formation
and what sits in it.
San Juan County's productive geology centers on the Pennsylvanian-age Paradox Formation, which contains both the conventional carbonate reservoirs that source Greater Aneth and the unconventional Cane Creek shale interval. The plays sit at very different depths and have very different operator profiles.
The Paradox Formation is the cornerstone of San Juan County oil and gas production. It is a thick interval of marine carbonates, evaporites, and shales deposited during the Pennsylvanian period in a restricted marine basin. Greater Aneth and the surrounding fields produce from porous limestone reservoirs within the Paradox, primarily from the Desert Creek and Ismay zones.
For mineral owners, Paradox Formation production typically means long-life royalty income from carbonate reservoirs that have been producing for decades, often with secondary recovery (waterflood) and tertiary recovery (CO2 flood) techniques extending the productive life. Greater Aneth wells from the original 1956 development are still producing today.
The Cane Creek shale is an emerging horizontal target within the Pennsylvanian Paradox Formation in the northern Paradox Basin. Most current Cane Creek production comes from the Big Flat field area near Dead Horse Point State Park in the northwest part of the basin. Roughly two dozen horizontal wells have been drilled into the Cane Creek across the basin to date.
For San Juan County mineral owners, the Cane Creek represents future potential more than current production. The play has attracted research investment, including a major DOE-funded study at the University of Utah, but commercial-scale Cane Creek development across the southern Paradox has been limited.
Beyond Greater Aneth, the Paradox Basin contains over 100 smaller oil and gas fields, each typically containing 2 to 10 million barrels of original oil in place. Many of these fields have produced through primary recovery and have not yet seen secondary or tertiary techniques applied. Some are at risk of premature abandonment without enhanced recovery investment.
For mineral owners with interests in smaller Paradox fields, valuation considerations differ from Greater Aneth. The smaller fields have less remaining inventory, more variability in operator commitment, and often less reliable royalty income trajectories.
Who is drilling on your
San Juan County minerals.
San Juan County's operator landscape is small relative to the Uinta Basin and very different from the rest of Utah. The top oil producer in the county is Elk Operating Services LLC. The top gas producer is Capitol Operating Group LLC. A handful of other operators hold positions in smaller Paradox fields and the Cane Creek emerging play.
We know how these operators develop in San Juan County. Happy to give you context on yours.
Not all San Juan County
minerals are built the same.
San Juan County is the largest county in Utah by area and one of the most geologically and culturally diverse. Greater Aneth sits in the southeast corner. The Navajo Nation covers the southern third of the county. Bears Ears National Monument covers significant central acreage. Bears Ears, the Ute Mountain Ute reservation, and BLM lands all complicate the development picture across most sections of the county.
What your San Juan County
mineral rights are worth.
Valuation in San Juan County depends heavily on whether your minerals are fee, federal, Navajo Nation trust, or Ute Mountain Ute trust, and whether they are in Greater Aneth, a smaller Paradox field, the Cane Creek trend, or non-producing. The four scenarios below cover what we see most often.
We would rather look at real facts than speak in generalities. Send us what you have.
Utah rules,
Paradox Basin realities.
San Juan County operates under the Utah oil and gas regime for fee and state minerals, the BLM Monticello Field Office for federal minerals, and the Bureau of Indian Affairs for Navajo Nation and Ute Mountain Ute trust minerals. The on-the-ground realities reflect substantial overlap between these jurisdictions across most of the county.
The Utah DOGM and Paradox specifics
The Utah Division of Oil, Gas and Mining (DOGM) regulates oil and gas activity on state and private (fee) minerals in San Juan County. DOGM permits wells, conducts hearings on spacing and unitization applications, and maintains the public well database. Paradox Basin development tends to use field-level voluntary unit agreements, particularly in Greater Aneth where waterflood and CO2 flood operations require coordinated unitization across many sections.
The BLM Monticello Field Office and federal minerals
Federal minerals in San Juan County are administered by the BLM Monticello Field Office. This is a different field office than Vernal (which covers the Uinta Basin) and reflects the Paradox Basin's distinct administrative geography. Federal lease auctions are quarterly. Bears Ears National Monument considerations affect federal minerals in central San Juan.
The BIA, Navajo Nation, and Ute Mountain Ute
Most of Greater Aneth sits on Navajo Nation land, with mineral interests held in trust for the tribe or for individual allottees. The Navajo Nation Aneth Chapter and the Bureau of Indian Affairs both play roles in leasing and royalty administration. Ute Mountain Ute trust minerals in eastern San Juan County are administered through the BIA. The leasing process differs substantially from fee or federal minerals on both reservations.
Helium economics and gas-weighted production
Some Paradox Basin gas streams contain meaningful helium concentrations, which has its own commercial market separate from natural gas. Royalty owners on gas-weighted Paradox interests may see helium royalty calculations on their statements that differ from standard methane economics. This is unusual within Utah and worth understanding when evaluating royalty trajectories or sale economics.

Paradox status, April 2026
The Paradox Basin in southeastern Utah produces a small fraction of state oil output, with the legacy Greater Aneth field accounting for the majority of production. Per Utah DOGM records, Aneth continues to produce roughly eleven thousand barrels per day of oil from the Pennsylvanian carbonate reservoir, with CO2 flood enhanced recovery in continued use. For San Juan County mineral owners, the practical takeaway is that activity remains concentrated in the legacy field, with the Cane Creek shale a longer-term unconventional target rather than a current development focus.
