PRODUCTION FROM THE FIELD

Høykontrast Modus

Development

Tambar is a field in the southern part of the Norwegian sector in the North Sea, 16 kilometres southeast of the Ula field. The water depth is 70 metres. Tambar was discovered in 1983, and the plan for development and operation (PDO) was approved in 2000. The field has been developed with a remotely controlled wellhead platform tied-back to the Ula field. Production started in 2001.

Reservoir

Tambar produces oil from Upper Jurassic shallow marine sandstone in the Ula Formation. The reservoir lies at a depth of 4100-4200 metres and has generally very good characteristics.

Recovery

The field is produced by pressure depletion, with natural gas expansion combined with aquifer support. Gas lift is used to improve production performance.

Transport

The oil is transported by pipeline to Ula. After processing at Ula, the oil is exported in the pipeline system via the Ekofisk field to Teesside in the UK, while the gas is injected into the Ula reservoir to improve oil recovery.

Status

Production is steadily declining due to decreased reservoir pressure and increased water cut. A side-track from one of the existing wells is planned to be drilled in 2021. Studies are ongoing to evaluate water and/or gas injection to increase production.
