PRODUCTION FROM THE FIELD

Status

Due to good well performance, Vigdis production is above expectations. The strategy is to maintain reservoir pressure by water injection, while maximising production capacity and regularity. A subsea booster pump for accelerated and improved recovery will be installed in 2020 and start operation in 2021. Two infill production wells and one exploration well are planned to be drilled in 2020/2021.

Development

Vigdis is a field in the Tampen area in the northern part of the North Sea, between the Snorre, Statfjord and Gullfaks fields. The water depth is 280 metres. Vigdis was discovered in 1986, and the plan for development and operation (PDO) was approved in 1994. The field has been developed with seven subsea templates and two satellite wells connected to the Snorre A facility. Production started in 1997. Oil from Vigdis is processed in a dedicated processing module on Snorre A. Injection water is supplied from Snorre A and Statfjord C. A PDO for Vigdis Extension, including the discovery 34/7-23 S and adjoining deposits, was approved in 2002. The PDO for Vigdis Nordøst was approved in 2011.

Reservoir

Vigdis produces oil from sandstone in several deposits. The reservoir in the Vigdis Brent deposit is in the Middle Jurassic Brent Group, while the Vigdis Øst and Vigdis Nordøst deposits are in Upper Triassic and Lower Jurassic sandstone in the Statfjord Group. The Borg Nordvest deposit is in Upper Jurassic intra-Draupne sandstone. The reservoirs are at a depth of 2,200-2,600 metres and have generally good quality.

Recovery

The field is produced by pressure support using water injection. Some of the reservoirs are affected by pressure depletion on the Statfjord field.

Transport

The well stream from Vigdis is routed to Snorre A through two flowlines. Stabilised oil is transported by pipeline from Snorre A to Gullfaks A for storage and export. All produced gas from Vigdis is reinjected into the Snorre reservoir.
