VIDEO: Vega Subsea Field

A little over a year ago Wintershall took over the operatorship of the subsea oil and gas field Vega from Statoil. Vega is the BASF subsidiary’s first operated subsea tie-in field in Norway.

The Vega field is a subsea facility located in the Norwegian section of the North Sea at 375 meters water depth. It is tied back to the Gjøa platform, 28 km to the east. The production on Vega started in 2010. Wintershall is the operator of the field with a 55.6% working interest. Partners are Petoro (28.3%), Bayerngas (7.3%), GDF Suez (4.4%), and Idemitsu (4.4%).

The field consists of three seabed templates, Vega North, Vega Central and Vega South. Vega North and Vega Central were discovered in 1980 and 1982 respectively by Gulf Exploration. Mobil discovered Vega South in 1987.

Vega North and Central are gas condensate fields. The Vega South field is a gas condensate field overlain by an oil zone and produces by pressure depletion with the underlying gas reservoir, providing natural gas lift for the shallower oil zone.
