Williams Announces $5.5B Acquisition of Momentum Midstream
The major deal, one of the most significant private midstream transactions in the U.S., involves assets divested by EnCap Flatrock.
Williams has agreed to acquire Momentum Midstream for $5.5 billion, according to a report from Rigzone. The deal was announced Tuesday, August 4, 2026.
The transaction is described as one of "the most significant private midstream transactions in the U.S.," Rigzone reported. The assets are being divested by EnCap Flatrock, a private equity firm focused on energy infrastructure.
While specific asset locations were not detailed in the report, a transaction of this scale is significant for the broader midstream sector that serves oil and gas producing regions. For Bakken operators, consolidation among large midstream companies can impact market dynamics for natural gas gathering, processing, and transportation.
Major acquisitions often lead to expanded or optimized pipeline and processing networks. In a basin like the Bakken, which produces significant associated natural gas alongside its crude oil, efficient midstream infrastructure is critical for operators to manage costs and meet regulatory requirements for gas capture.
The deal underscores continued investment and consolidation in the midstream sector, which is essential for supporting production across key U.S. shale plays. The involvement of a major player like Williams signals confidence in the long-term need for natural gas infrastructure.
