The '''Sleipner gas field''' is a [[natural gas field]] in the [[North Sea]], about {{convert|250|km}} west of [[Stavanger]], Norway. Two parts of the field are in production, Sleipner West (proven in 1974), and Sleipner East (1981). The field produces natural gas and light oil condensates from sandstone structures about {{convert|2500|m|ft}} below sea level. It is operated by [[Statoil]]. The field is named after the steed [[Sleipnir]] in [[Norse mythology]].
==Reserves and production==
As of the end of 2005, the estimated recoverable reserves for the Sleipner West and East fields were 51.6 billion cubic metres of natural gas, 4.4 million tonnes of [[natural gas liquids]], and 3.9 million cubic metres of condensates. Daily production of the field in 2008 was {{convert|300|koilbbl/d}} equivalents, 36 million cubic metres of natural gas per day, and 14,000 cubic metres of condensate per day.
Sleipner field consists of four platforms. The [[Sleipner A offshore platform|Sleipner A platform]] is located on the Sleipner East and the Sleipner B platform is located on the Sleipner West. Sleipner B is operated remotely from the Sleipner A via an [[umbilical cable]]. The Sleipner T [[carbon dioxide]] treatment platform is linked physically to the Sleipner A platform by a bridge and to the Sleipner B wellhead platform by {{convert|12.5|km|adj=on}} carbon dioxide flow line. The Sleipner Riser platform, serving the [[Langeled pipeline|Langeled]] and [[Zeepipe]] pipelines, is located on the Sleipner East field.
==Carbon capture and storage project==
The Sleipner West field is used as facility for [[carbon capture and storage]] (CCS). It is the world's first offshore CCS plant, operative since October 1996. Carbon dioxide is treated on the Sleipner T treatment platform. After that carbon dioxide is transported by flow line to the Sleipner B wellhead platform where it is injected to the reservoir. Norwegian natural gas pipelines' operator [[Gassco]] has proposed to build a {{convert|240|km|adj=on}} carbon dioxide pipeline from [[Kårstø]] to transport carbon dioxide from the [[Kårstø Power Station|Kårstø power station]].
