Williams Momentum Midstream Deal Could Reach $5.5 Billion

Tulsa-Based Williams Nears $5.5 Billion Momentum Midstream Pipeline Deal

The proposed Williams Momentum Midstream deal could become one of the largest acquisitions in the history of the Tulsa-based energy company. Williams is reportedly in advanced talks to acquire natural gas pipeline operator Momentum Midstream for approximately $5.5 billion, potentially expanding the company's ability to move natural gas from the Haynesville shale to major Gulf Coast LNG export terminals.

The negotiations involve purchasing Momentum from private equity firm EnCap Flatrock Midstream. A final agreement has not been announced, and the companies could still fail to reach a deal.

Williams Momentum Midstream Deal Could Expand Gulf Coast Pipeline Network

The Williams Momentum Midstream deal would give Williams additional infrastructure connecting natural gas production in East Texas and northern Louisiana with growing energy demand along the Gulf Coast.

Momentum says its operations include approximately 4,000 miles of pipeline with system capacity of 6 billion cubic feet per day. Its network has 91 interconnections and serves 10 LNG facilities and 26 power plants.

One of Momentum's key assets is the 250-mile NG3 pipeline, which directly connects growing Haynesville natural gas production to LNG demand near Gillis, Louisiana. The pipeline has a total capacity of 2.3 billion cubic feet per day.

More information about the company's pipeline network is available through Momentum Midstream operations.

Natural Gas Demand Drives Major Energy Investments

The potential acquisition comes as U.S. energy companies position themselves for increasing demand from LNG exports, power generation and rapidly expanding AI data centers.

Williams already operates more than 30,000 miles of pipeline infrastructure across the United States. The Tulsa-based company describes its business as connecting American energy supplies with homes, businesses and other major energy users.

The company has also continued investing in projects tied to future electricity demand. On Monday, Williams announced a separate $5.34 billion investment agreement with a Blackstone-led group involving five power generation projects. The partnership is aimed at supporting rising energy demand tied partly to artificial intelligence and data centers.

Additional information about Williams' energy infrastructure operations is available through Williams.

Potential Acquisition Would Strengthen Williams LNG Strategy

Momentum's pipeline network is strategically positioned near the Haynesville shale, one of the country's major natural gas-producing regions.

Its infrastructure directly serves LNG facilities, power plants and industrial customers across the Gulf Coast. Momentum reports more than 140 customers and more than 1 million dedicated acres connected to its systems.

For Williams, acquiring the company could provide immediate access to established pipeline capacity rather than relying entirely on construction of new infrastructure as natural gas demand increases.

Williams has already expanded its Gulf Coast footprint through investments connected to the Louisiana LNG project and Driftwood Pipeline. In 2025, the company announced an agreement to acquire an 80% ownership interest and become operator of Driftwood Pipeline LLC.

The proposed $5.5 billion Momentum acquisition remains under negotiation. Neither Williams nor Momentum has announced a final agreement.

If completed, the transaction would significantly expand the Tulsa company's position in the natural gas corridor connecting Haynesville production to Gulf Coast LNG markets.
