About the field
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
- Development
- Troll Brent B is a field near the Troll field in the northern part of the North Sea. The water depth is 340 metres. Troll Brent B was discovered in 2005, and was granted an exemption from the plan for development and operation (PDO) in 2017. Troll Brent B was planned to be developed with one multilateral production well drilled from the O-template connected to Troll C.
- Reservoir
- The reservoir contains oil in sandstone of Middle Jurassic age in the Brent Group, stratigraphically underlying producing reservoirs on the Troll field. The reservoir is at a depth of 1900 metres.
- Recovery strategy
- The field was planned to be produced by pressure depletion.
- Transport
- There was no production from Troll Brent B.
- Status
- During drilling of the production well, oil reserves were proven to be significantly lower than originally assumed. It was therefore decided to be uneconomical to start production on the Troll Brent B field. The well was plugged; however, the well slot is available to be used for potential new targets on Troll Vest.
