About the field
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
- Development
- Vega is a field in the northern part of the North Sea, 30 kilometres west of the Gjøa field. The water depth is 370 metres. Vega was discovered in 1981. The field consists of three separate structures: Vega Nord, Vega Sentral and Vega Sør. The plan for development and operation (PDO) for Vega Nord and Vega Sentral was approved in 2007. In 2011, the field was unitised with Vega Sør. The field has been developed with three 4-slot subsea templates, one on each structure. They are tied to the processing facility on the Gjøa platform. A total of nine production wells have been drilled. The production started in 2010.
- Reservoir
- Vega produces gas and condensate from Middle Jurassic shallow marine sandstone in the Brent Group. Vega Sør additionally has an oil zone overlying the gas/condensate deposit. The reservoirs are at a depth of 3500 metres, and the quality varies from poor to medium across the field.
- Recovery strategy
- The field is produced by pressure depletion.
- Transport
- The well stream is sent to the Gjøa field for processing. Oil and condensate are transported from Gjøa to the Troll Oil Pipeline II for further transport to the Mongstad terminal. The rich gas is exported to the Far North Liquids and Associated Gas System (FLAGS) on the British continental shelf for further transport to St Fergus in the UK.
- Status
- Vega production is on decline. The main reservoir management focus on Vega is to secure stable production from all the three structures within the available gas capacity on Gjøa. The strategy is to prioritise production from Vega Sør and then fill up the capacity with production from Vega Nord and Sentral.
