ONEOK is acquiring Brazos Midstream's Permian Midland Basin natural gas gathering and processing assets for $4.425 billion, according to the announcement. The deal expands ONEOK's midstream footprint in the Permian, the largest oil and natural gas basin in the United States.
The acquisition adds natural gas gathering and processing capacity in the Midland Basin, where crude and associated gas production have grown substantially over the past five years. ONEOK operates roughly 40,000 miles of pipelines and 600 processing facilities across North America; the Brazos assets strengthen its exposure to production acreage where crude output has exceeded 5 million barrels per day.
Brazos Midstream is a private midstream company focused on the Permian Basin. The transaction values the assets at a scale typical for anchor acquisitions in basin infrastructure; the deal size sits alongside prior major midstream consolidations in the region, where infrastructure providers have moved to capture fee-based revenue from producers locked into long-term takeaway agreements.
The Permian has driven U.S. oil output to record levels since 2018, with associated gas production climbing alongside crude. Midstream companies in the region have sought to expand capacity and lock in volumes through asset purchases and long-term contracts as producers invest in new wells and lateral drilling.
ONEOK completed the acquisition announcement in late August 2026. The company did not disclose a close date or regulatory approvals required for the transaction.
Midstream consolidation in the Permian has accelerated since 2024, with several operators acquiring gathering and processing assets to capture growth in associated gas volumes that accompany crude production. ONEOK's prior acquisitions in the region have focused on similar fee-based infrastructure tied to producer activity and output growth.
The metric that tracks execution is when ONEOK announces final close of the transaction, which would confirm the deal completion and provide updated asset details and financial impact.
