Field: TAMBAR ØST

General information

Current activity status:	PRODUCING
Discovery wellbore:	1/3-K-5
Discovery year:	2007

Description Norwegian

Development

Tambar Øst has been developed with one production well drilled from the Tambar facility.

Reservoir

The reservoir is in sandstones of Late Jurassic age, deposi-ted in a shallow marine environment. The reservoir lies at a depth of 4 050 – 4 200 metres and the quality varies.

Recovery strategy

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

Transport

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.

Status

Production from Tambar Øst has not met expectations and the reserve estimates have been reduced.
