Project Profile
Value: US$1 billion
Location: Karratha, Western Australia
Depth: 126m
Discovery: 2006
Start-up Year: 2017
The Persephone gas field is located in offshore petroleum production license WA-1-L, some 135km, northwest of Karratha, Western Australia, in a water depth of about 126m. The field was discovered in 2006 by the exploration well Persephone-1, which is located approximately 8km north-east of the North West Shelf Project’s North Rankin Complex.
The North Rankin Complex, which will take gas from the Persephone, is a single integrated facility comprising the interconnected North Rankin A (NRA) and North Rankin B (NRB) platforms and associated subsea infrastructure, including two export trunklines which run between NRC and the onshore Karratha Gas Plant (KGP).
The project involves a two well, 7km subsea tieback from the Persephone field to the existing North Rankin Complex. The total investment for the project is expected to be approximately A$1.2 billion (US$916 million) , with project start-up expected in early 2018. Woodside will operate Persephone, and holds a 16.7% stake alongside project partners including BP, Chevron, Shell and BHP Billiton.
