Skirne which also includes the Byggve deposit is an offshore gas field in the North Sea located 24 kilometres east of the Heimdal gas field and 140 kilometres from Stavanger, Norway. The depth of the water in the field area is 120 metres. The Skirne field was discovered in 1990 and consists of Middle Jurassic sandstones of the Brent Group. Skirne deposit lies 2,370 metres deep. The Byggve field is located 16 km east of the Heimdal gas field and was discovered in 1991 and consists of Middle Jurassic sandstones of the Brent Group. Byggve deposit lies 2,900 metres deep. Production at Skirne and Byggve started in 2004. Both Skirne and Byggve have an estimated 230 billion cubic feet (bcf) (6.5×109 m3) of natural gas and about 10 million barrels of condensate, combined. Both Skirne and Byggve are considered satellites to Heimdal field and are connected to it by subsea pipelines. The fields are interconnected through two single-well tie-backs and transported to treatment facilities at Heimdal Gas Center, from which the processed gas is then exported to the United Kingdom through the Vesterled pipeline. The field was discovred in 1990 and came on stream on 3 March 2004.
TotalFinaElf which is the operator had received the approval from Norwegian Ministry of Petroleum and Energy for development of the fields in 2002. Other stakeholders are Petoro, Statoil and Centrica. Expected project duration is 6 years and produce 140 million cubic feet per day (4.0×106 m3/d) of gas and 7,000 barrels per day (1,100 m3/d) of condensate. Total investment including the Vale satellite has been nearly approximately US$46 billion which also included modifications on Heimdal, drilling operations, subsea templates and pipelines.
