Intro
Valhall Flanke Sør is an unmanned wellhead platform on the southern flank of the Valhall field in the Norwegian North Sea, installed in 2003 to access peripheral reservoir volumes and tie back to the Valhall central processing complex.
Field
The Valhall field is a mature oil field in ~70-m water depth producing oil from chalk reservoirs in the Tor and Hod Formations. Peripheral flank developments extend recovery beyond the field centre.
Facilities
The Valhall Flanke Sør platform hosts wellheads and drilling slots for production wells targeting the southern flank reservoir. It ties back via subsea flowlines and control umbilicals to the Valhall field centre’s processing platforms where separation, stabilisation and export functions occur. The structure includes minimal topside processing, with remote power and control delivered via subsea cables from the main Valhall complex; periodic maintenance occurs via helicopter. Produced hydrocarbons join central headers for export through pipelines to Ekofisk (oil) and Norpipe (gas). Utility systems are limited to safety, corrosion protection, and remote instrumentation; well control and emergency shutdown systems ensure safe integration with the wider Valhall processing infrastructure.
