The Powder River Basin (PRB) is a large structural basin in northeast Wyoming and southeast Montana that has been a significant energy-producing region for over a century. The basin is the largest coal-producing region in the United States and has become an increasingly important oil and gas province as horizontal drilling has unlocked production from tight formations including the Turner, Mowry, Niobrara, Sussex, and Frontier. Coalbed methane from the Wyodak and Fort Union coals was a major gas play in the 2000s. The transition to horizontal oil development has reinvigorated the basin and increased mineral values significantly in the core development areas. We actively buy mineral rights, royalty interests, NPRI, and ORRI across the Powder River Basin.
Approximate location of the Powder River Basin shown in tan
The Powder River Basin is an asymmetric structural basin bounded by the Bighorn Mountains to the west, the Black Hills to the east, and the Miles City Arch to the north. Sediments reach over 17,000 feet thick in the deepest part of the basin. The primary horizontal oil targets are the Turner Sandstone (a Cretaceous tight sandstone at 9,000 to 12,000 feet), the Mowry Shale, the Niobrara Formation, and the Sussex and Shannon sandstones. These formations produce light, sweet crude oil. The shallower Fort Union and Wasatch coals produced significant coalbed methane at depths of 200 to 2,000 feet, though CBM activity has declined with lower gas prices. Deeper conventional targets include the Frontier Formation, Muddy Sandstone, and Minnelusa Formation.
Devon Energy, Anschutz Exploration, Continental Resources, and EOG Resources are among the most active horizontal operators in the Powder River Basin. Chesapeake Energy and Anadarko (now Oxy) built early positions. On the CBM side, legacy operators include Fidelity Exploration & Production, Bill Barrett Corporation (now SRC Energy), and various smaller independents. The basin has seen growing interest from large operators as horizontal well performance has improved.
Powder River Basin mineral values are driven by the producing formation (horizontal oil vs. CBM), location within the basin, and operator activity level. Acreage in the core horizontal development area of Converse and Campbell counties with Turner and Niobrara production commands the highest valuations. CBM-only minerals support lower valuations reflecting the lower per-well productivity and the decline in CBM drilling activity. Non-producing minerals with horizontal development potential are valued based on proximity to existing horizontal wells and operator drilling plans. Fee vs. federal mineral ownership is also a key consideration.
The Powder River Basin is a tale of two assets, and sellers need to know which one they own. Horizontal oil minerals in the Converse and Campbell county fairway — Turner, Niobrara, Parkman — are an appreciating story with genuine undeveloped inventory, and they price accordingly. Legacy coalbed methane minerals from the 2000s boom are the opposite: low-rate, late-life gas production whose value is mostly its remaining tail. Families who leased during the CBM era often assume their minerals are spent when they actually sit in (or beside) the modern horizontal fairway — the single most common pleasant surprise we deliver in this basin.
PRB title carries Wyoming’s usual complications: checkerboarded federal sections, federal units, and split estates, all of which we underwrite as routine work rather than discounting blindly. Send a county and operator name — or just the old CBM lease — and we will tell you in writing within 48 hours what the interest is worth in today’s basin, including whether horizontal development is approaching your tract.
Additional counties we cover within the Powder River Basin, sorted by recent oil and gas activity:
The primary horizontal targets in the PRB are the Turner Sandstone, Mowry Shale, Niobrara Formation, and Sussex/Shannon sandstones. The Turner has been the most actively developed and has delivered strong well results in Converse and Campbell counties. The Niobrara, which is a prolific producer in the DJ Basin to the south, is also productive in parts of the PRB. Operators continue to delineate and test additional formations.
CBM was a major play in the PRB during the 2000s, with thousands of wells drilled in the Wyodak and Fort Union coals. Lower natural gas prices and the relatively low per-well productivity of CBM wells caused drilling activity to decline significantly after 2008. Many CBM wells are still producing but at low rates. The shift to horizontal oil development has largely replaced CBM as the primary driver of mineral value in the basin.
A significant portion of the mineral estate in the Powder River Basin is owned by the federal government (BLM) or the State of Wyoming. Federal mineral leasing and permitting timelines can affect development pace on tracts with federal minerals. However, fee (privately owned) minerals remain actively bought and sold, and we are experienced in evaluating fee minerals within mixed-ownership drilling units that include federal or state minerals.
