  • The Chiswick Platform is a Normally Unattended Installation (NUI)
  • The platform is tied-back 19km southeast to the Markham Gas Field installation, from where gas is exported via the West Gas Transport pipeline to the NAM-operated Den Helder plant.
  • The field was initially discovered by a BP consortium in 1984, but not developed due to the complex nature of the subsurface structure.
  • Centrica Energy acquired 100% equity in the field in 2006 and proceeded to engineer a technical solution for developing the field, based on the multiple fraccing of long horizontal wells.
  • This process is based on creating fractures in the rock using proppants to increase the exposure of the well to the surrounding formation and to make the gas flow more easily.
  • The field came on-stream in 2007 and there are now four wells operational.
  • The Kew Gas Field is a subsea tieback to the Chiswick platform


  • SLP Engineering: Designed, procured, fabricated & hooked up the Chiswick Platform
  • KWSubsea:
    • Detailed design of a 12km 10" with 1.5" piggy back from platform to platform including tie-in spool
