In 2012, the plan for improvement and operation (PDO) for Asgard subsea compression was authorised by the authorities, and the primary section of Åsgard subsea compression got here on stream in 2015. The sphere got here on stream with Asgard A in 1999 and Asgard B in 2000, in line with the discharge.
Beneath the PDO, Equinor said that there can be a necessity for elevated stress in the long run to compensate for the stress drop within the reservoirs.

The CO2 is transported by way of ships from Heidelberg Supplies’ cement manufacturing facility in Brevik after which offloaded and transported by way of a 100-kilometer pipeline and injected into the Aurora reservoir underneath the seabed of the North Sea, in line with the assertion.
The enlargement of Northern Lights builds on present infrastructure and consists of further onshore storage tanks, a brand new jetty, and extra injection wells, Equinor mentioned.
