INPEX to Acquire Minority Share in Browse

Posted 15 May 2026

TOKYO, JAPAN - INPEX CORPORATION (INPEX) announced today that through its subsidiary, INPEX Mirai Upstream Pty Ltd, it has entered a sales and purchase agreement with PetroChina International Investment (Australia) Pty Ltd (CNPC) to acquire CNPC’s 10.67 percent participating interest in the Browse joint venture, including the Browse titles covering the Brecknock, Calliance and Torosa gas fields offshore Western Australia.

Completion of the sales and purchase transaction is conditional on a number of matters including regulatory and Browse joint venture participant approvals.

The development of Browse has the potential to make a significant contribution to energy security in Australia and in the Asia-Pacific region. The Browse fields, which were discovered between 1971 and 2000, contain a combined contingent resource of about 13.9 trillion cubic feet of dry gas and approximately 390 million barrels of condensate.

INPEX has been a proud participant in the Australian business community since 1986. The company’s Australian energy portfolio includes Ichthys LNG as operator, and participating interests in Prelude FLNG, Darwin LNG, Van Gogh and Ravensworth.

INPEX is committed to recognising and respecting Aboriginal and Torres Strait Islander peoples whose cultures have existed in Australia for more than 65,000 years.

In particular, we acknowledge the Larrakia people as the recognised Traditional Owners of the land and waters where Ichthys LNG onshore facilities are located, in addition to the Whadjuk Nyoongar people on whose lands our Perth office is situated. Furthermore, Broome and Djarindjin are important logistical locations for transit of our offshore workforce, and we therefore extend our acknowledgement to the Yawuru, Bardi and Jawi peoples, respectively.

INPEX acknowledges the important role Aboriginal and Torres Strait Islander peoples continue to play in the development of our business in Australia and pay our respects to their Elders – past and present.
