Description Norwegian

Development

Oseberg Øst is an oil field located east of Oseberg in the northern part of the North Sea. The field has been developed with an integrated fixed facility with accommodation, drilling equipment and first stage separation of oil, water and gas. The sea depth in the area is about 160 metres.

Reservoir

The main reservoir consists of two structures, separated by a sealing fault. The structures contain several oil bearing layers of Middle Jurassic sandstones in the Brent Group, with varying reservoir characteristics. The reservoir lies at a depth of 2 700 – 3 100 metres.

Recovery strategy

The field is produced by partial pressure support from water injection and water alternating gas injection (WAG).

Transport

The oil is sent by pipeline to the Oseberg Field Centre for further processing and transport through the Oseberg Transport System (OTS) to the Sture terminal. The gas is mainly used for injection, gas lift and fuel.

Status

The drilling equipment on the Oseberg Øst facility has been upgraded. One main challenge is to balance production with a limited availability of water and gas for injection.
