Statoil Vigdis Extension


Norway Block 34/7

Landmark: FMC Technologies’ first-generation enhanced horizontal systems in Norway

The Vigdis Extension field is situated between the Vigdis and Tordis fields in the Tampen area of the North Sea. It is expected to produce 50 mmbo. The development was built with a seabed installation, production and installation tubing and control cables. A total of six wells were drilled: three production wells and three wells for water injection.

Statoil and the other partners are utilizing the available capacity in the existing infrastructure in the area in connection with this development. Vigdis Extension started oil production at the end of 2003. The seabed unit is linked to the existing seabed installation for Vigdis. Oil and gas will be processed in the existing process plant for Vigdis on Snorre TLP.

Snorre A, 4 miles (7 km) away, remotely controls production from Vigdis and processes its oil before this output gets piped to Statoil's Gullfaks A platform for storage and export. Vigdis gas is reinjected into Snorre, and gas from Vigdis Extension will be transported via Snorre A to the Statpipe/Norpipe system.

On January 1, 2003, the operatorship was transferred from Norsk Hydro to Statoil (today Statoil).
