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.
