The North West Shelf venture participants and CNOOC Limited signed conditional agreements in May 2003 that allowed CNOOC to acquire an interest in NWS Venture titles and to secure rights to use North West Shelf Venture infrastructure to process gas. All conditions have now been satisfied.

A new joint venture, called the China LNG Joint Venture, has been established within the overall North West Shelf project to accommodate CNOOC and to supply LNG to the Guangdong LNG project in China.

CNOOC will hold a 25% share in the new joint venture, with each of the existing NWS Venture participants taking 12.5%.

CNOOC will be entitled to gas and associated liquids roughly equivalent to a 5.3% interest in the gas in North West Shelf Venture titles.

CNOOC will pay a tariff to the North West Shelf Venture participants to use infrastructure to produce and process gas and associated liquids from its acquired gas resources.

The six equal participants in the North West Shelf Venture are: BHP Billiton Petroleum (North West Shelf) Pty Ltd; BP Developments Australia Pty Ltd; ChevronTexaco Australia Pty Ltd; Japan Australia LNG (MIMI) Pty Ltd; Shell Development (Australia) Proprietary Limited; and Woodside Energy Ltd (operator).
