Description Norwegian

Development

Visund is an oil field to the east of the Snorre field in the northern part of the North Sea. The sea depth in the area is 335 metres. The development includes a semi-submersible integrated accommodation, drilling and processing steel facility (Visund A). The northern part of Visund has been developed with a subsea template about 10 kilometres to the north of Visund A. The PDO for gas export was approved on 04.10.2002. The subsea template, Visund Nord, was closed down in 2006 after a gas leakage on the Visund A facility.

Reservoir

Visund contains oil and gas in several tilted fault blocks with varying pressure and liquid systems. The reservoirs are in Middle and Lower Jurassic and Upper Triassic sandstones in the Brent Group and the Statfjord and Lunde formations. The reservoirs lie at a depth of 2 900 - 3 000 metres.

Recovery strategy

Oil production is driven by gas injection and water alternating gas injection (WAG). Produced water is also reinjected into one of the reservoirs. Limited gas export started in 2005.

Transport

The oil is sent by pipeline to Gullfaks A for storage and export with oil from Gullfaks. Gas is exported to the Kvitebjørn gas pipeline and on to Kollsnes. At Kollsnes, NGL is separated out and the dry gas further exported to the market.

Status

A challenge for Visund is to maintain reservoir pressure to optimize oil recovery before gas export levels increase. One measure being evaluated is to access more water to increase water injection. The gas export has been reduced. One exploration target near Visund was drilled in 2008 and proved additional resources which can be tied in to the field. An area development plan for new resources is expected to be prepared in 2009. An exploration target east of Visund Nord is planned to be drilled in 2009. A possible discovery may be tied to a new development of Visund Nord.
