Rev was discovered in February 2001 and commenced production in January 2009. The three wells are situated on the NCS, 84 m water depth, and a buried production pipeline carries the gas and condensate to the Armada platform on the UKCS for processing. Rev currently produces periodically with about 8-10 cycles each year.

On 16th April 2018 the Rev UKCS decommissioning programme was approved by the Secretary of State. A Copy of this document along with the EIA and Comparative assessment can be found below and also on OPRED website, see link.

Gudrun is developed with a traditional steel platform resting on the seabed. The platform have capacity for partial treatment of oil and gas, before the hydrocarbons are sent via pipeline to Sleipner.

Oil and gas is transported from the Gudrun field to the Sleipner A platform. The gas is transported onward to the gas markets from Sleipner A. The oil is routed together with the Sleipner condensate to Kårstø for shipping.

Gudrun was first proven in 1975.

Visund is an oil and gas field in blocks 34/8 and 34/7, 22 kilometres north-east of the Gullfaks field in the Tampen area of the Norwegian North Sea.

It came on stream in the spring of 1999, this development embraces a floating production, drilling and quarters platform.

The subsea-completed wells on the field are tied back to the floater with flexible risers. Oil is piped to Gullfaks for storage and export. The Visund field began producing gas and exporting it to continental Europe on 7 October 2005.

Mikkel lies 35 kilometres south of the Midgard deposit on Equinor’s Åsgard field in the Norwegian Sea. It has been developed with a subsea production facility tied back to the seabed installations on Midgard, which in turn form part of the Åsgard development.

The Mikkel system comprises two subsea templates with a total of three production wells.

The condensate will go in existing flowlines to the Åsgard C storage ship for export, while gas is piped through the Åsgard Transport trunkline to the Kårstø complex north of Stavanger.

Mikkel has been producing gas and condensate (light oil) since 1 August 2003.
