New technology increases gas recovery

London, September 26, 2025, (Oilandgaspress) –– Equinor and partners in Åsgard and Mikkel licences have started phase 2 of Åsgard subsea compression in the Norwegian Sea.

The project will help maintain production from the field by increasing the pressure in the pipelines between the wells and the Åsgard B platform.

The first plan for development and operation (PDO) of Åsgard was approved in 1996. The field came on stream with Åsgard A in 1999 and Åsgard B in 2000. In 2012, the PDO for Åsgard subsea compression was approved by the authorities, and the first phase of Åsgard subsea compression came on stream in 2015.

This was the world’s first facility for gas compression on the seabed and the result of extensive technological development. The plans described that there would be a need for increased pressure in the long term to compensate for the pressure drop in the reservoirs. The first compressor module in phase two was replaced in 2023, now the second and final module has been installed, at a depth of 270 meters.
