The consent applies to modifications to parts of the production facility at Heidrun and commissioning of this modified facility.
The purpose of the modification is to reduce inlet pressure from a selection of wells, which will increase oil production from the wells.
Heidrun is at Haltenbanken in the Norwegian Sea, around 225 west of Brønnøysund. The field has been developed using a floating concrete tension leg facility placed over a template.
Production at Heidrun began in 1995.
