PRODUCTION FROM THE FIELD

Development

Visund is a field located in the northern part of the North Sea, northeast of the Gullfaks field. The water depth is 335 metres. Visund was discovered in 1986, and the plan for development and operation (PDO) was approved in 1996. The field is developed with a semi-submersible, integrated accommodation, drilling and processing facility (Visund A) and a subsea facility in the northern part of the field. Production started in 1999. A PDO for the gas phase was approved in 2002 and gas export started in 2005. A PDO exemption was granted in 2013 for the deposits Rhea and Titan east on Visund. The subsea facility on Visund north was replaced in 2013 due to problems with the original template. In 2017, a PDO exemption was granted for another subsea template on Visund north.

Reservoir

Visund produces oil and gas from sandstone of Late Triassic and Early Jurassic age in the Lunde Formation and Statfjord Group, and of Middle Jurassic age in the Brent Group. The reservoirs are in several tilted fault blocks with varying pressure and liquid systems. The reservoirs lie at a depth of 2,900-3,000 metres. Reservoir quality is generally good in the main reservoirs.

Recovery

Recovery strategy varies between the reservoirs at Visund. Oil in the Brent reservoirs is mainly produced by pressure maintenance from gas and water injection. The Statfjord reservoirs are partly produced by pressure depletion. Increased gas export since 2015 has reduced gas available for injection and reduced reservoir pressure in parts of the field.

Transport

The oil is transported by pipeline to the Gullfaks A facility for storage and export via tankers. Gas is exported through the Kvitebjørn Gas Pipeline and on to the Kollsnes terminal, where the NGL is separated and the dry gas is further exported to the market.

Status

A challenge for Visund is to maintain reservoir pressure within drilling limits and optimise oil recovery, while increasing gas exports. New production wells are being drilled continuously, some with exploration pilots. Additional resources on the eastern and northeastern flanks are being evaluated. The new subsea template on Visund north started production in September 2018.
