Sleipner (gas field)
Under the umbrella term Sleipner field , the gas and condensate fields Sleipner Ost and Sleipner West and their satellite extensions Loke , Grungne and Alfa Nord in the Norwegian part of the North Sea are summarized. The gas field was named after Sleipnir , Odin's eight-legged steed .
The fields are located around 260 km west of the Norwegian coast and are operated by Equinor (formerly Statoil ).
CO 2 storage
The natural gas produced has a CO 2 content that is higher than the requirements of the export partners. Therefore, on a part of the platform Sleipner complex, the CO 2 separated, but not released into the atmosphere, but as part of a 10 million euro EU project in layers of rock 800 meters below the sea pressed .
The gaseous CO 2 is compressed and injected into a bore specially made for this purpose. The storage rock is a sandstone from the Utsira formation.
Around one million tons of CO 2 have been stored annually since 1996 .
Investigations in 2013 discovered faults in the rock, so that a future gas leak from the reservoir is very likely.
Surveillance or monitoring
Seismic data are collected every two years ( 4D seismic ). The spread of the CO 2 can be checked in a spatial representation by comparison with the previous measurement .
