Woodside has extended the life of its North West Shelf LNG plant with a $5 billion upgrade to the North Rankin field.
Yesterday the company announced the redevelopment of the North Rankin project, 135km off the coast of Karratha, had been completed, with first gas exported to the Karratha Gas Plant.
The redevelopment involved the construction of a second platform as well as modification and refurbishment of the existing facility.
The company said the project will enable the recovery of 5 trillion cubic feet of low pressure reserves from both North Rankin and Perseus fields.
It is expected the redevelopment will keep the North West Shelf in production until 2040.
Woodside chief, Peter Coleman, said the North Rankin project had achieved start-up on time and on budget.
"Start-up is a major milestone given the complexities of integrating a new 65,000-tonne facility next to an existing offshore production platform," Coleman said
"The redevelopment maximises the value of Australia's largest operating oil and gas project by extending the resource life and supporting the North West Shelf project's onshore gas commitments."
