- Phase 2 of Åsgard subsea compression started in the Norwegian Sea.
- The first compressor module was replaced in 2023, with the second installed at 270 meters depth.
- The system has contributed to NOK 175 billion in increased value from the field.
- Recovery rate from Mikkel and Midgard fields will increase to 90%, adding 306 million barrels of oil equivalent.
Project Overview
Equinor and partners have initiated phase 2 of the Åsgard subsea compression project in the Norwegian Sea. This phase aims to maintain production by increasing pressure in pipelines between wells and the Åsgard B platform.
Technological Advancements
The project involves the development and qualification of next-generation compressor modules, enhancing gas recovery from existing fields. The first compressor module in phase two was replaced in 2023, and the second module has been installed at a depth of 270 meters.
Historical Context
The Åsgard field's first development and operation plan was approved in 1996, with production starting in 1999 and 2000. The first phase of subsea compression began in 2015, marking the world's first seabed gas compression facility.
Economic Impact
The compressor system has operated with nearly 100% uptime for ten years, contributing approximately NOK 175 billion in increased value from the field. Combined recovery rates from the Mikkel and Midgard fields are expected to reach 90%, equating to an additional 306 million barrels of oil equivalent.
