A pipeline company has proposed a massive new “expansion” to ship Canadian crude to a storage facility and interconnect to other pipelines near Guernsey, potentially giving Powder River Basin producers a leg up in the North American market.
Casper-based Bridger Pipeline formed a subsidiary, Bridger Pipeline Expansion to get Canadian crude to Guernsey. The pipeline would stretch 645 miles from Phillips County, Montana, to Bridger’s oil storage terminal and pipeline interconnect near Guernsey.
The expansion would open the spigot for 550,000 barrels per day of crude, the company says. Although the crude would mostly pass through eastern Wyoming, the venture opens opportunities for Wyoming oil producers in the region for more transportation access to U.S. refineries and shipping ports, according to Bridger and local industry officials.
“It would be the biggest project in our history, if it comes to fruition,” Bridger Pipeline spokesperson Bill Salvin told WyoFile on Friday. “We are, however, in the really early stages of the project. But we’re very excited about it.”

Industry trade groups speculate the Bridger Pipeline Expansion is part of a competitive scramble to fill a gap left by TC Energy’s Keystone XL project. That company, in 2021, abandoned the controversial project in the face of major opposition and protests. It would have transported Canadian tar-sands oil into the U.S. market via a route extending through Montana, South Dakota and Nebraska.
Among many challenges for Keystone XL was acquiring new rights-of-way easements. Though the Bridger Pipeline Expansion proposal requires some new rights-of-way, that’s not the case for the 210-mile Wyoming segment, according to Salvin.
“All of that distance is within, or parallel to, existing pipeline corridors,” Salvin said.
The Wyoming segment would pass through Crook, Weston, Niobrara, Goshen and Platte counties.
Bridger Pipeline, a subsidiary of Casper-based True Companies, submitted a notice of intent to the Montana Department of Environmental Quality in January and noted it will formally initiate environmental applications to the agency. Salvin told WyoFile he’s uncertain about the full spectrum of regulatory requirements in Wyoming.
However, the company regards the Cowboy State as a great fit for the project, he said. “This [project proposal] just highlights how important the region is and how Wyoming is a very good place for energy projects like this.”
Reached for comment, the Petroleum Association of Wyoming said the proposed pipeline only stands to benefit Wyoming producers and the state.
“Investments like these, along with continued growth in areas like the Powder River Basin, show Wyoming will continue to play an important role in the nation’s energy markets,” PAW Vice President and Director of Communications Ryan McConnaughey told WyoFile. “Connecting in Guernsey allows product to be transported to refining hubs like Cushing, Oklahoma.”
