Skirne which also includes the Byggve deposit[1] is an offshore gas field in the North Sea located east of the Heimdal gas field and from Stavanger, Norway.[2] The depth of the water in the field area is 120m (390feet). Both Skirne and Byggve are considered satellites to Heimdal field and are connected to it by subsea pipelines.[3] TotalFinaElf which is the operator had received the approval from Norwegian Ministry of Petroleum and Energy for development of the fields in 2002. The company holds 40% interest in the project. Other stakeholders are Petoro and Centrica.[4] Both Skirne and Byggve have an estimated of natural gas and about 10 million barrels of condensate, combined.[5]
The Skirne field was discovered in 1990.[3] and consists of Middle Jurassic sandstones of the Brent Group. Skirne deposit lies 2370m (7,780feet) deep.[1]
The Byggve field is located 16km (10miles) east of the Heimdal gas field[3] and was discovered in 1991.[3] and consists of Middle Jurassic sandstones of the Brent Group. Byggve deposit lies 2900m (9,500feet) deep.[1]
Production at Skirne and Byggve started in 2004. Expected project duration is 6 years[3] and produce of gas and of condensate.[5]
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.[4]
Total investment including the Vale satellite has been nearly 4 billion NOK which also included modifications on Heimdal, drilling operations, subsea templates and pipelines.[4]
