Åsgard is located on the Halten Bank in the Norwegian Sea, around 200 kilometres off mid-Norway and 50 kilometres south of the Heidrun field.
The Åsgard A oil production vessel arrived at the field on 8 February 1999 and started production on 19 May.
Åsgard B is a semi-submersible gas and condensate processing platform, which came on stream on 1 October 2000.
Åsgard C is a condensate storage vessel tied back to the field.
Åsgard consists of the Midgard, Smørbukk and Smørbukk South deposits. In addition, the Mikkel and Yttergryta gas fields are tied back to the Åsgard infrastructure.
Midgard spreads over blocks 6507/11 and 6407/2. Smørbukk and Smørbukk South are located in block 6506/11.
Midgard was proven by Saga in 1981. Statoil found Smørbukk in 1984 and Smørbukk South in 1985. In 1995 the licence rights were coordinated in a new ownership structure with Statoil as operator.
The largest development on the Norwegian continental shelf (NCS)
The entire Åsgard field development ranks among the largest developments on the NCS, embracing a total of 63 production and injection wells drilled through 19 subsea templates.
Production from the Morvin (4 wells and 2 subsea templates) and Mikkel (3 wells and 2 subsea templates) fields is also directed to Åsgard B.
Water depth in the area is 240-310 metres.
Åsgard A - oil production vessel.
Åsgard B - floating gas production platform.
Åsgard C - Condensate storage tanker (light oil).
Production from the Kristin and Mikkel fields is carried to Åsgard C.
The overall Åsgard development comprises:
- development of the field itself in the Norwegian Sea
- the Åsgard Transport gas pipeline from the field to the Kårstø processing plant north of Stavanger
- the Kårstø expansion project
- the Europipe II gas trunkline from Kårstø to Dornum on the German coast.
Crude oil, condensate and gas are produced from Åsgard. Crude and condensate are mixed to form a light oil called Åsgard blend. The liquid is pumped from storage tanks into shuttle tankers which sail between the fields and the different refineries.
Gas from Åsgard is piped through Åsgard Transport to the Kårstø processing
complex, north of Stavanger. The heavier components, such as ethane, propane, butane and naphtha are separated out at Kårstø. The dry gas is piped to continental Europe.
Åsgard supplies about 11 billion cubic metres of gas annually to European
The Åsgard development links the Halten Bank area to Norway's gas transport system in the North Sea, putting long-standing plans for a pipeline connection into effect.
Growing demand for Norwegian gas from continental Europe has made this possible, and Åsgard will help to meet the planned expansion in Norway's gas exports.
Gas from the field is piped through the Åsgard Transport line to the treatment plant at Kårstø north of Stavanger and on to European customers.
Oil produced via the A vessel is shipped from the field by shuttle tankers.
