What happened with Woodside Energy (ASX:WDS) and the Browse gas project?

Woodside Energy is considering exercising its pre-emption rights to match a rival bid from Japanese energy giant Inpex. Inpex announced plans to acquire PetroChina's 10.67% stake in the Browse gas fields off Western Australia.

Why is the Browse gas field significant for Woodside Energy (ASX:WDS)?

The Browse project is Australia's largest undeveloped gas resource, encompassing the Brecknock, Calliance, and Torosa fields. For Woodside, the asset is crucial because it is earmarked as essential backfill gas to sustain production at the North West Shelf liquefied natural gas (LNG) infrastructure.

How much is the Browse gas project expected to cost, and what are the financial metrics?

The total development cost for the delayed Browse project is estimated at A$48.7 billion (approximately $35 billion), which includes integrated carbon capture and storage infrastructure. While the exact price Inpex offered for PetroChina's 10.67% stake remains undisclosed, historical context shows PetroChina originally bought the position from BHP for $1.63 billion back in 2012.

What is management’s strategy regarding this transaction?

Woodside CEO Liz Westcott stated that management will "absolutely assess pre-emption," which aligns with their standard capital allocation and risk management protocols. Woodside is pushing forward with the asset's development and is currently tendering for engineering work.

How might this news affect Woodside Energy's (ASX:WDS) share price short term?

The short-term impact is balanced but carries potential capital expenditure overhang. While acquiring a larger stake prevents a rival from controlling the resource, matching the bid would require a significant near-term cash outlay on an already expensive A$48.7 billion project.

What are the main bull and bear points for retail investors considering ASX:WDS?

The bull case is that Woodside secures strategic control over Australia's largest untapped gas reserve, ensuring long-term feed gas for its North West Shelf LNG plant. The bear case revolves around execution risk and massive capital intensive requirements, given the project's historical delays and heavy A$48.7 billion price tag.

Woodside evaluates pre-emption for Browse gas stake

Written by Heidi Cuthbert Published May. 20 2026

Woodside Energy (ASX:WDS) will consider matching an offer from Inpex to buy PetroChina's 10.67% stake in the Browse gas fields off the coast of Western Australia, CEO Liz Westcott confirmed on May 20.

Speaking at the Australian Energy Producers conference, Westcott stated that Woodside would "absolutely assess pre-emption" regarding the transaction, which involves Australia’s largest undeveloped gas resource.

The move follows Inpex's announcement on Friday that it intends to acquire the stake in the Brecknock, Calliance, and Torosa fields, though financial details remain undisclosed.

PetroChina originally purchased its share from BHP for $1.63 billion in 2012. The delayed Browse project, operated by Woodside, is currently estimated to cost A$48.7 billion, a figure that includes carbon capture infrastructure.

The asset is earmarked as critical backfill for the North West Shelf liquefied natural gas facility in Western Australia.

While MST analyst Saul Kavonic suggested Inpex might aim to divert the gas to its Ichthys plant in Darwin, Westcott declined to speculate, noting she has yet to hold formal discussions with the Japanese energy giant.

However, she welcomed Inpex's involvement, calling them an "established operator" with significant local activity.

Woodside is presently tendering for engineering work on the field's development.

The transaction remains subject to regulatory approvals and joint venture agreements.

The remaining Browse partners include BP—the project's largest stakeholder—and Japan LNG, a joint venture between Mitsui and Mitsubishi.

Finalising the deal could reshape regional gas dynamics as Inpex concurrently eyes expansion at its Ichthys facility.

At the time of reporting, Woodside Energy’s share price was $32.39.
