Åsgard subsea gas compression
This page is available in English only
In September 2015, Åsgard became the world’s first subsea gas compression facility to commence operation. Now, five years later, the technology from this project is one of our most important measures for delivering volumes from existing fields on the Norwegian continental shelf (NCS).
The technology will increase recovery from the Mikkel and Midgard structures by around 282 million barrels of oil equivalent.
With Åsgard subsea gas compression, we are one step closer to realising our vision of a subsea factory. Subsea processing, and gas compression in particular, are important advances to develop fields in deep waters and harsh environments.
The Midgard and Mikkel gas reservoirs in the Åsgard field have been developed as subsea field installations. The wellstreams from both fields, located 50 and 70 kilometres away respectively, are sent in the same pipeline to the Åsgard B platform.
Analyses showed that by the end of 2015 the pressure in the reservoirs would have been too low to ensure stable flows and satisfactory production on the Åsgard B platform. Compression was needed to ensure high gas flows and recovery rates.
