Increased recovery due to new technology at the Vigdis oil field

A pump on the seabed gives the Vigdis oil field in the North Sea a boost that increases production by around 16 million barrels.

The Vigdis subsea field has produced oil via the Snorre field for 24 years. When the field came on stream in 1997, it was expected to produce 200 million barrels. So far, it has produced twice as much, and based on new estimates the recoverable resources are 475 million barrels.

Use of subsea pumps is particularly important to deep-water fields with long distances between subsea facilities and platforms. Other examples of such projects are Tordis subsea separation and boosting, as well as Gullfaks subsea compression and Åsgard subsea compression.

The contract for supplying the boosting system, including the template and trawl protection, was awarded to OneSubsea, with engineering in Bergen and assembly at Horsøy near Bergen.
