Tambar Øst has been developed with one production well drilled from the Tambar facility.
The reservoir is in sandstones of Late Jurassic age, deposited in a shallow marine environment. The reservoir lies at a depth of 4 050 – 4 200 metres and the quality varies.
The field is recovered by pressure depletion and limited aquifer drive.
The oil is transported to Ula via Tambar. After processing at Ula, the oil is exported in the existing pipeline system to Teesside via Ekofisk. The gas is used for gas injection in the Ula reservoir to improve oil recovery.
Production from Tambar Øst has not met expectations and the reserve estimates have been reduced.
