Wheatstone Project

9th February 2016 - Projects
One of Australia’s most significant resource developments.

The Wheatstone offshore gas resource, about 200 km north of Onslow, was discovered by Chevron in 2004. In March 2008, the company announced its intention to develop Wheatstone via an onshore liquefied natural gas (LNG) and domestic gas plant. A final investment decision to proceed with the Wheatstone Project was made in September 2011, with construction starting in December the same year. 

The foundation project, located 12 km west of Onslow on the Pilbara coast of Western Australia, includes two LNG trains with a combined capacity of 8.9 million tons per annum (MTPA) and a 200 terajoule per day domestic gas plant. The project has approval to expand to 25 MTPA of LNG.

Upstream - Offshore facilities

The offshore facilities of the Wheatstone Project will gather and partially process gas and associated condensate, and deliver it onshore for further processing. Key offshore components include:

  • Well infrastructure and subsea installations
  • A gas processing platform in 73 m of water
  • A 225 km trunkline to transport gas from the platform to the onshore facilities at Ashburton North
Downstream - Onshore facilities

Once onshore at Ashburton North, the gas and condensate will be processed further. Key onshore components include:

  • A slug-catcher to separate the gas and liquids
  • An initial two-train LNG processing plant
  • A domestic gas processing plant and pipeline connecting to the Dampier-to-Bunbury Natural Gas Pipeline
  • LNG and condensate storage tanks
  • Marine facilities including a shipping channel, turning basin, materials offloading facility and export jetty
  • Workforce accommodation village and associated infrastructure at Ashburton North

The project is targeting the first LNG deliveries by mid 2017.

To date, the Wheatstone Project has generated more than 7,000 jobs. The USD29 billion Wheatstone Project is being developed and will be operated by Chevron.
