  • The Conwy and Corfe Fields are to be developed as a subsea tieback to the BHP Billiton operated Douglas Complex.
  • The development consists of the installation of a Normally Unattended Installation (NUI) and the drilling of three platform production wells, two penetrating the Conwy reservoir and one penetrating the Corfe reservoir.
  • Two water injection wells will also be drilled, to support production from each field.
