Woodside Energy Ltd. has sold a 10% interest in Louisiana LNG LLC and and 80% interest and operatorship of Driftwood Pipeline LLC to Williams Cos. As part of the transaction, Williams will contribute its share expenditure—roughly $1.9 billion—to the LNG plant and pipeline and assumes LNG offtake obligations for 10% of produced volumes.
Williams will also build and operate the 2.4-bcfd Line 200 pipeline, which will use 42-in. OD pipe to transport natural gas from the 5.4-bcfd Driftwood pipeline to the 27.6-million tonne/year (tpy) Louisiana LNG plant.
Woodside chief executive officer Meg O’Neill noted that this was Williams’ first investment in LNG and that the project was “on track to deliver first LNG in 2029.”
Woodside last month signed its first long-term LNG offtake agreement with Petronas, which could include production from Louisiana LNG. First deliveries under the deal are also targeted for 2029.
The deal was executed at a purchase price of $250 million with an effective date of Jan. 1, 2025. The total proceeds received were $378 million, including proportionate capital reimbursement since the effective date.
Relatedly, Williams agreed to sell its minority interest in the South Mansfield upstream asset of Louisiana’s Haynesville shale to JERA Co. Inc. for $398 million plus deferred monthly payments through 2029. The total transaction value is estimated at $1.5 billion.
South Mansfield currently produces 500 MMcfd and includes 200 undeveloped locations, JERA said. The company plans to increase production to 1 bcfd.
GEP Haynesville II LLC is also selling its majority interest in South Mansfield upstream but will continue to operate and develop the asset on a fixed fee basis. GEP continues to own and operate other Haynesville shale assets not involved in this transaction.
Under JERA’s ownership, Williams will continue to gather natural gas volumes from South Mansfield and will deliver those volumes through its Louisiana Energy Gateway (LEG) system for deliveries into Gulf Coast LNG markets. As part of the deal, Williams will further expand its gathering system for South Mansfield production growth, and the volume commitment to LEG from South Mansfield will also increase.
The South Mansfield sale is expected to close by end 2025.
