Summary Information

  • Operator: Apache
  • Country: Australia
  • Location: west-northwest of Dampier
  • Production start:
  • Partners: KUFPEC
  • Type: Gas
  • Estimated Reserves:
  • Production Volume:


  • The Julimar and Brunello gas fields, discovered by Apache and Kuwait Foreign Petroleum Exploration Co. (KUFPEC) in 2007, are located offshore in exploration permit WA-356-P, approximately 180 kilometres (km) (112 miles) west-northwest of Dampier in Western Australia.
  • The JDP will consist of subsea gas production wells drilled from three drill centers and two satellite locations. Each of the wells will be tied into a subsea manifold. The manifolds will be connected using intra-field flowlines and linked to the offshore Wheatstone platform by twin raw gas production lines.
  • The field will supply gas to the Wheatstone LNG Terminal


  • J P Kenny: Front end engineering design (FEED) for the subsea development
  • Allseas Construction Contractors: Supply of transportation and installation services for the Julimar development pipeline field components, including the 25km long, twin 18" corrosion resistant alloy (CRA) pipelines, the 4" carbon steel utility pipe line and ancillary pipe line equipment
  • Subsea 7: Supply of transportation and installation services for the JDP subsea field equipment including the production manifolds, spools, jumpers and the 25km-long subsea electro-hydraulic umbilical
  • Oceaneering: Construction and supply of a 25km-long Subsea Electro-Hydraulic Umbilical
  • GE: Subsea manifolds, well systems and fully integrated subsea and topside control systems
    • Project management, engineering, transportation and subsea installation of electro-hydraulic steel tube umbilical, two heavy lift subsea manifolds, flying leads and jumpers
    • Procurement, fabrication, transportation and installation of diverless tie-in spools


  • 2007 - Julimar Offshore Gas Field discovered
  • 2010 - J P Kenny awarded FEED contract
  • 2011 - The development received Australian government environmental approval
  • 2012 - Subsea and pipeline contracts awarded
