Tyra Field is the largest gas condensate field in the Danish Sector of the North Sea.[1] It was discovered in 1968 and production started in 1984.[2] The field is owned by Dansk Undergrunds Consortium, a partnership between Maersk Oil, Royal Dutch Shell and Chevron Corporation, and operated by Maersk Oil.[3]
The total proven reserves of the Tyra gas field are around 1.25 billion cubic feet (35×106 m3), and production is centered around 237.8 million cubic feet per day (6.73×106 m3/d).[4] The reservoir depth is about 2,000 metres (6,600 ft) and it covers area of 90 kilometres (56 mi) in the water depth of 37–40 metres (121–130 ft).[2]
The Tyra Field has two production complexes named Tyra West and Tyra East, connected by pipelines. Tyra West includes oil and gas processing plants which in addition to the gas produced at the Tyra field, processes also gas from Halfdan and Valdemar fields. The complex consists of two wellhead platforms, one processing and accommodation platform, and one gas flare stack. Tyra East processes also oil and gas from Valdemar, Roar, Svend, Tyra Southeast, Harald, Lulita, Gorm and Dan fields. It consists of two wellhead platforms, one processing and accommodation platform, one gas flare stack, and one riser platform.[2]
In total, the field has 20 gas-producing wells, and 28 oil and gas-producing wells.[2]
Produced oil is transported to the Gorm E riser platform in the Gorm field, and further through the subsea pipeline to the oil terminal in Fredericia, Denmark. Produced natural gas is transported from the Tyra East riser platform to Nybro, Denmark, and from Tyra West riser platform to the Netherlands through the Tyra West – F3 and NOGAT pipelines.[3]
