About the field
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
- Development
- Trestakk is a field in the central part of the Norwegian Sea, 20 kilometres south of the Åsgard field. The water depth is 300 metres. Trestakk was proven in 1986 and the plan for development and operation (PDO) was approved in 2017. The development concept consists of one subsea template with four well slots and an additional satellite well. The subsea installation is tied-back to the Åsgard A facility for processing and gas injection. The production started in 2019.
- Reservoir
- Trestakk produces oil from shallow marine sandstone of Middle Jurassic age in the Garn Formation. The reservoir is at a depth of 3900 metres and has moderate quality.
- Recovery strategy
- The Field is produced by gas injection.
- Transport
- The well stream is transported to the Åsgard A facility for processing. Oil and condensate are temporarily stored at Åsgard A, and then shipped to market by shuttle tankers. The gas is exported through the Åsgard Transport System (ÅTS) to the Kårstø terminal.
- Status
- The production from the field has been lower than anticipated due to poorer reservoir properties than predicted and lower gas injection volumes. Starting in mid-2023, an updated gas injection strategy has been implemented, resulting in stabilised production rates. New infill targets are being evaluated.
