Development

Tambar Øst is a field in the southern part of the Norwegian sector in the North Sea, two kilometres east of the Tambar field. The water depth is 70 metres. Tambar Øst was discovered in 2007. In the same year, an exemption for a plan for development and operation (PDO) was granted and the field started production. The field has been developed with one production well drilled from the Tambar facility.

Reservoir

Tambar Øst produces oil and some gas from shallow marine sandstone of Late Jurassic age in the Farsund Formation. The reservoir is at a depth of 4050-4200 metres and has varying quality.

Recovery strategy

The field is produced by pressure depletion and limited aquifer drive.

Transport

The oil is transported from the Tambar field to the Ula facility. After processing at Ula, the oil is exported in the existing pipeline system via the Ekofisk field to Teesside in the UK. The gas is used for gas injection in the Ula reservoir to improve oil recovery.

Status

The production from Tambar Øst had been shut-in temporarily since 2019 for pressure build-up, and was restarted in October 2023.
