Woodside Energy has confirmed it has exercised a pre-emptive right to acquire PetroChina’s 10.67% interest in the Browse gas fields located off the coast of Western Australia, a move that halts a proposed sale of that stake to Japan’s Inpex. Under the terms disclosed, Woodside will pay $225 million to PetroChina and will reimburse cash call contributions PetroChina has made since mid-2025.
The company said the agreement contains a contingent payment arrangement that could transfer up to $175 million to Inpex, but only if the Browse joint venture makes a final investment decision to develop the Brecknock, Calliance, and Torosa fields. Woodside noted the transaction will increase its ownership in the Browse venture to 41.27% once completed.
Market reaction was immediate: Woodside shares fell by more than 2% following the announcement. The company and market commentary also pointed to a concurrent drop in oil prices as an additional factor weighing on the stock.
The Browse area remains one of Australia’s largest undeveloped gas resources, and Woodside’s increased stake reflects a consolidation of ownership within the venture. The contingent payment to Inpex means the eventual cash flows tied to the sale could change depending on whether the joint venture proceeds to a development decision for the named fields.
This transaction covers a direct purchase price and reimbursement of recent cash calls but stops short of guaranteeing project approval or development timetables - elements that remain subject to future joint-venture decisions. The deal prevents the immediate transfer of PetroChina’s 10.67% stake to Inpex and leaves potential future payments contingent on project milestones being met.
Context and next steps
Woodside will finalize the purchase for $225 million and reimburse PetroChina for its cash calls since mid-2025. If the Browse partners approve full-field development for Brecknock, Calliance, and Torosa, Inpex may become entitled to a contingent payment of up to $175 million. Otherwise, no contingent payment obligation will be triggered under the terms described.
The market will likely watch both energy price movements and any signals from the Browse joint venture regarding a final investment decision, which would determine whether the contingent payment becomes payable and would influence project timing and capital commitments.
