Sigyn Gas by Esso

Sigyn gas field is located in block 16/7 in the Norwegian North Sea. The discovery well is 12km south-east of the Sleipner A platform. Sigyn field was discovered in 1982. Esso Norway operates the field, with a 40% interest. Statoil holds a 50% interest, while Norsk Hydro holds the 10%. In 2001, Statoil signed NOK375 million of contracts for the development. These included a NOK200 million contract to ABB to carry out modification work on the Sleipner A platform. Coflexip Stena Offshore was contracted to install a seabed template, flowlines and control system. Esso is responsible for reservoir. The Sigyn field development plans envisaged a subsea satellite with three wells tied through two flow lines to the Statoil-operated Sleipner A platform. The satellites are remotely operated from the platform.First production began from one well in Sigyn East and two in Sigyn West, all drilled from the same subsea template. This was roughly three months ahead of the original schedule. The field is expected to produce for ten years. The production licence 072 was awarded in 1981 and the field was discovered in 1982 and added to in 1997.
