The development of the Åsgard subsea gas compression was approved in the Norwegian parliament.
Åsgard subsea gas compression will increase recovery from Mikkel and Midgard fields by around 280 million barrels of oil equivalent, stated Statoil.
As time passes, the pressure from Midgard and Mikkel will be too low to maintain stable flow and high production to the Åsgard B platform. To compensate for this, Statoil will install compressors on the seabed near the wellhead to increase pressure in the production flowlines.
All of the major contracts in the Åsgard subsea compression project have already been awarded, and most of the detailed engineering is complete. This spring the company plans to start assembly of modules at Aker Solutions’ yard in Egersund, Rogaland.
According to plan, Åsgard subsea gas compression will be ready for start-up in first half 2015. For the most part, the project will be the first user of technology never before applied under comparable conditions, added Statoil. For this reason, a very extensive and thorough qualification program has been implemented for the new technology, including a program for continuation with realistic sea tests at the company’s test facilities at Kårstø, K-lab, during the course of the year.
“Åsgard subsea gas compression is a profitable and robust project. Development of the world’s first compression facility for gas under water is a challenging task,” said Astrid Jørgenvåg, production director for the Åsgard area.
Staoil, operates the Åsgard area, with 34.57% working interest; Petoro AS, 35.69%; Eni Norge AS, 14.82%; Total E&P Norge AS, 7.68%; and ExxonMobil Development Norway, 7.24%.
