Rockies Update: Uinta, Powder River, Green River

The Forgotten Region's Quiet Comeback

The Rocky Mountain region doesn't get the attention its oil and gas production warrants. No single basin in the Rockies commands the headlines that the Permian, Eagle Ford, or Appalachian basins generate daily. But collectively — across the Uinta Basin in Utah, the Powder River Basin spanning Wyoming and Montana, and the Green River Basin in Wyoming/Colorado — the Rockies represent a significant and underappreciated component of U.S. upstream activity.

Combined Rockies production (oil plus gas) runs approximately 900,000–1,000,000 boe/d as of mid-2025. That's roughly equivalent to the entire production of a mid-sized OPEC nation — and it's been growing quietly while investors focused on the Permian supercycle.

Uinta Basin: The Utah Surprise

The Uinta Basin of northeastern Utah is the Rockies' most dynamic story. Production from the Wasatch, Green River, and Uteland Butte formations has grown steadily, driven by Ovintiv, Crescent Energy (which absorbed the former SRC Energy Uinta position), and private operators including Verdad Resources.

The Uinta's peculiarity is its waxy crude — high pour-point oil that requires specialized handling but commands a premium in specific refinery configurations. Tesoro (now Marathon Petroleum) and small Utah refineries have historically taken Uinta crude at advantaged economics. The crude quality story is a moat that larger, undifferentiated light tight oil producers can't replicate.

Infrastructure has been the limiting factor. The Uinta has no direct pipeline to Gulf Coast markets — production moves via truck, rail, and limited local pipelines to Utah refineries and the Rockies pipeline network. A proposed pipeline connection (the Uinta Basin Railway project, now reoriented as a crude-by-rail expansion) would unlock substantially more volume if financed and permitted. Watch this project as a potential 2026–2027 catalyst.

Powder River Basin: PRB's Patient Play

The Powder River Basin (PRB) spans northeastern Wyoming and southeastern Montana and holds stacked pay potential across the Niobrara, Turner, Mowry, Parkman, and Teapot formations. The basin has been a zone of active drilling for a decade, but production growth has been more measured than initial enthusiasm suggested.

Chesapeake Energy (pre-rebranding) made a significant PRB commitment with its Vine Energy acquisition. Devon Energy remains one of the basin's largest operators. Anschutz Exploration, privately held, controls premium acreage in the core.

The PRB's production currently runs near 110,000–130,000 bbl/d of oil equivalent. Growth potential is real but constrained by infrastructure — particularly gas takeaway. The PRB is a natural gas-rich basin with oil in the spotlight, and flaring rates have historically been elevated when gas gathering capacity fell behind drilling programs. Recent midstream investments by Crestwood Midstream (now part of Energy Transfer) have improved the situation.

At $65–70 WTI, PRB development economics are marginal in Tier 2 locations. Tier 1 positions — tight acreage in the core Turner fairway — generate strong returns. The basin will likely see modest activity growth in H2 2025 but won't be a headline production driver.

Green River Basin: The Gas Basin with Staying Power

The Green River Basin in southwest Wyoming and northwest Colorado is fundamentally a natural gas basin — home to the Pinedale Anticline and Jonah Field, which have been producing since the 1990s. Peak production from these fields exceeded 2 Bcf/d in the early 2010s; current output has declined to roughly 600–800 MMcf/d as reservoir pressure has declined in the mature fields.

Ultra Petroleum (now restructured and operating as a private entity), Jonah Energy (private), and Pinedale Anticline Project operators continue developing the basin with infill drilling. The high-pressure, tight-sand reservoirs here require careful reservoir management — rates decline steeply without sustained drilling programs.

The Green River gas feeds into the Rockies Express Pipeline system (REX) and connects to Midwest markets. As basis differentials between Rockies and Henry Hub fluctuate, basin economics swing significantly. Current REX-connected gas prices have been favorable, supporting activity.

The Infrastructure Thesis

The common thread across all three Rockies basins is infrastructure limitation as the binding constraint on production growth — not reservoir quality, not operator capability, not land position. This creates an interesting investment angle: midstream infrastructure in the Rockies is a less competitive space than in the Permian or Appalachia, potentially offering superior returns for patient capital.

The Rockies region is unlikely to produce the next banner headline acquisition. But for operators who understand the basins, the infrastructure gaps, and the crude quality stories, there is durable value being created in a region the market has largely overlooked.
