Texas-based Silver Creek Midstream Holdings is set to sell its Powder River Basin crude oil midstream assets in Wyoming to a subsidiary of Plains All American Pipeline (PAA) and Plains GP Holdings (PAGP) for about $585 million in cash, Silver Creek said in a Wednesday statement.
The deal, expected to close in the fourth quarter of 2026, involves the sale of SCM PR II LLC, the parent company of Silver Creek's Powder River Basin assets, and is owned by Tailwater Capital and The Energy & Minerals Group.
Silver Creek's Powder River Basin operations include about 600 miles of crude oil gathering and transmission pipelines, with approximately 350,000 barrels per day of operating capacity and 1.2 million barrels of operational storage capacity.
The assets also include a 49% non-operated interest in the Powder River Gateway Joint Venture.
The system is supported by approximately 915,000 dedicated acres under long-term agreements and minimum volume commitments, with an average remaining contract term of more than eight years, Silver Creek said. The network serves producers in the Powder River Basin and connects to regional transportation hubs including Guernsey and Fort Laramie.
Silver Creek currently manages about 125,000 barrels of oil per day.
