Williams (WMB) has jumped into the LNG business in a big way. The company reached a strategic partnership with Woodside Energy (WDS) under which it will invest in the 16.5 Mtpa (2.5 Bcf/d) Louisiana LNG project. WMB will acquire a 10% interest in Louisiana LNG and has committed to a 1.5 Mtpa (~200 MMcf/d) offtake obligation.
Under the deal announced Oct. 22, Williams will also acquire an 80% ownership stake and become operator of Driftwood Pipeline. The company will assume responsibility for construction of Driftwood Line 200, a 3+ Bcf/d header line extending from Lake Charles to the Gillis hub. At Gillis, Driftwood Line 200 will connect with WMB’s Transcontinental and Louisiana Energy Gateway (LEG), as well as several other pipelines. In total, WMB expects to invest $1.9B under the agreement.
The deal with Williams gives Woodside much-needed counterparty backing for Louisiana LNG. WDS in late April announced a $17.5B project FID, despite having only one customer (a 1 Mtpa sales and purchase agreement with Uniper) at the time. WDS in April sold a 40% stake in the project to Stonepeak for $5.7B.
Along with the Woodside announcement, WMB and GEP Haynesville II reached an agreement with JERA to sell 100% of their respective interests in the South Mansfield upstream assets in DeSoto Parish, LA. The properties produce more than 500 MMcf/d currently, and the deal includes a plan to develop ~200 undeveloped locations to grow production to over 1 Bcf/d. JERA is one of the largest buyers of US LNG, with a total of 5.5 Mtpa contracted between five LNG projects (see table).

This is just the latest in a string of Haynesville land grabs by Japanese companies in an effort to ensure security of supply. Last year, Tokyo Gas bought Rockcliff Energy for $2.7B, and Mitsubishi reportedly was in talks to buy Aethon Energy Management earlier this year. Mitsui has been among the companies active in the exploratory Western Haynesville, alongside Comstock Resources (CRK) and Aethon. Expand Energy (EXE) also recently committed to the emerging play, acquiring 75,000+ net acres in the region for $178MM.
All of this buzz around the Haynesville is for good reason. East Daley Analytics’ current balanced forecast in the Macro Supply & Demand Report sees nearly 4 Bcf/d of ArkLaTex production growth in 2026. While this amount of growth is ambitious based on current producer guidance, we expect a step change in gas demand from new LNG facilities and data centers will put serious upward pressure on gas prices next year. Among leading gas basins, the Haynesville has demonstrated a unique ability to respond quickly to changing fundamentals. See our upcoming Dirty Little Secrets publication for in-depth analysis of the full range of possibilities next year and beyond. – Oren Pilant Tickers: CRK, EXE, WDS, WMB.
The Permian Basin at a Crossroads: Download the Latest White Paper 
The Permian Basin is the heart of the US energy industry, supplying half of crude oil and NGL production and nearly 20% of natural gas. Yet market pressures are forcing changes, prompting billions in new pipeline investments and reorienting how operators approach the basin. East Daley’s new white paper, The Permian Basin at a Crossroads, is the first of a 3-part series looking at the shifts underway in the Permian. In this series, we reveal how LNG demand and AI data centers could transform Permian gas into a primary revenue driver. We also review the multi-billion-dollar infrastructure needed to unlock this shift, and what’s at stake for oil, gas and midstream operators. — Click here to download the The Permian Basin at a Crossroads white paper!
