Description

  • The permits cover over 1 million acres and are located approximately 115 miles off the northwest coast of Australia in water depths of approximately 3,600 feet
  • The Equus Gas Project Basis of Design comprises an offshore processing facility and a pipeline to shore, with landfall near Onslow.
  • Development will be phased, with the initial development comprising three production wells linked by subsea infrastructure to a Floating Production Storage and Offloading (FPSO) unit. Facilities on-board the FPSO will include gas dehydration, condensate stripping and gas compression. Water depth at the well locations is 1000m to 1200m.
  • Dry sales gas will be piped to shore by way of a 220km pipeline, with onshore facilities dependent on the outcome of gas marketing arrangements. Gas supply is expected to be up to 250 terajoules of gas a day.
  • Gas is to be supplied to North West Shelf LNG
