PAA to Buy Silver Creek Assets for $585 Million
Plains All American Pipeline agrees to acquire Powder River Basin assets for $585 million, adding 600 miles of pipelines and 350,000 barrels per day of capacity to its Rockies network.
Plains All American Pipeline, L.P. (PAA) has agreed to acquire the Powder River Basin assets of Silver Creek Midstream for approximately $585 million in cash. The transaction, expected to close in the fourth quarter of 2026, is designed to expand the company’s direct connectivity to crude oil producers in the region. PAA will gain access to nearly 600 miles of gathering and transmission pipelines, increasing its operating capacity by more than 350,000 barrels per day.
The acquisition also secures approximately 1.2 million barrels of storage capacity and a 49% non-operated interest in the Powder River Gateway joint venture. This deal strengthens PAA’s footprint in the Rockies by linking the new assets to existing infrastructure at the Guernsey and Fort Laramie hubs, which feed into long-haul systems delivering crude to Cushing. The business case is supported by 915,000 dedicated acres and long-term contract tenors averaging over eight years.
Acquisition Adds Scale and Synergies
Current throughput for the Silver Creek assets is approximately 125,000 barrels per day, with management noting potential for volume growth and operating synergies. The addition of these pipelines complements PAA’s earlier Cactus III acquisition, which expanded its crude oil footprint and provided access to the Corpus Christi export market. In 2026, PAA captured $50 million in targeted synergies from Cactus III, with another $50 million in corporate efficiencies expected by year-end and an additional $50 million identified for 2027.
Midstream Sector Consolidation Accelerates
PAA’s move is part of a broader trend of consolidation among oil and gas midstream companies seeking to broaden their footprints. On September 9, 2026, Enbridge Inc. agreed to acquire Tallgrass Energy’s crude oil business for $2.55 billion, which includes a 51% stake in the same Powder River Gateway joint venture that PAA is buying into. Similarly, Williams completed its $5.5-billion acquisition of Momentum Midstream in September, adding over 4,000 miles of pipelines in the Haynesville region.
Western Midstream also completed a $1.6-billion acquisition of Brazos Delaware in June, expanding its Delaware Basin processing capacity by 460 million cubic feet per day. These transactions reflect a strategic shift toward scale and operational efficiency across key producing regions. According to GN auto stocks/energy-stocks: pipeline capacity, such acquisitions are driving market reach and long-term growth for midstream operators.
Unit Performance Outpaces Industry
In the past three months, PAA units have rallied 17.8%, outperforming the industry’s 8.7% growth. Despite this recent price movement, the company currently holds a Zacks Rank #4, indicating a Sell rating based on consensus estimates. The Silver Creek acquisition is expected to provide tangible benefits through increased throughput and cost savings, though the full impact on unit value remains subject to regulatory approvals and market conditions.
