+++ Description

• Vega is located directly north of the Fram field in the northern part of the North Sea.
• The water depth in the area is about 370 metres. The field comprises three separate gas and condensate deposits, 35/8-1, 35/8-2 Vega and 35/11-2 Vega Sør.
• The deposits were previously named **Camilla**, **Belinda** and **Fram B**
• The wellstream is sent by pipeline to Gjøa for processing. Oil and condensate are transported from Gjøa in a new pipeline tied to Troll Oljerør II for further transport to Mongstad.
• The rich gas is exported in a pipeline to Far North Liquids And Associated Gas System (Flags) Pipeline on the British continental shelf for further transport to SEGAL St Fergus Gas Processing Terminal.

+++ Contractors

• **FMC Technologies:** Six subsea trees, three manifolds with protection structures, related control systems and a workover system
• **Aker Solutions:** Gjoa tie back FEED

+++ History

• 1980 - Vega Gas And Condensate Field discovered
• 2007 - FMC Technologies Chosen to Supply Subsea Systems
• 2010 - Vega comes on stream
• 2013 - Statoil reduced its stake to 24%
• 2014 - Statoil sold its remaining stake to Wintershall

+++ Geology

• The Vega reservoirs are in Middle Jurassic sandstones in the Brent Group, with high temperature and pressure initially, and relatively low permeability. The reservoir depth is about 3 500 metres. Vega Sør contains gas and condensate with an oil zone in the upper part of the Middle Jurassic Brent Group, at a depth of 3 500 metres.
