(Reuters) -U.S.-based gas pipeline operator Williams will invest $1.9 billion in Woodside Energy’s $17.5 billion liquefied natural gas production and export terminal under construction in Louisiana, the companies said.

Under the agreement, Williams will own a 10% stake in the project’s infrastructure company and 80% of the Driftwood pipeline that will supply natural gas to the Louisiana LNG project.

Woodside’s ownership of the Louisiana LNG project will be reduced to 50%, as the Australian energy company sold a 40% stake to U.S. investor Stonepeak for $5.7 billion in April.

Woodside said it expected total proceeds of $378 million from the latest deal, cutting its total capital spending on the project to $9.9 billion from a previous estimate of $11.8 billion.
