Heimdal gas field

Heimdal (Norwegian: Heimdalfeltet) is an offshore natural gas field in the North Sea located 212 kilometres (132 mi) northwest of the Stavanger, Norway. Heimdal serves as a connection hub for processing and distribution of natural gas from satellite fields.[1]

The field was discovered in 1972. The depth of the sea at location is 120 metres (390 ft). The field was developed with an integrated drilling, production and accommodation facility with a steel jacket including a riser facility in 1999.[2] The gas from the field is transported to Kårstø as well as to St. Fergus in Scotland. After construction of the Heimdal gas center, a new gas pipeline was connected to the existing one from Frigg gas field to St. Fergus. The gas is also transported to Grane oil field for gas injection. The condensate is sent by pipeline to Brae oilfield. Heimdal also gets gas from the Oseberg field center for further transportation through Statpipe system.[3]

Ownership

The Heimdal field is operated by Equinor. Partners are Equinor (39.44%), Centrica Resources (23.79%), Petoro (20%), and TotalFinaElf Exploration Norge AS (16.75%). Originally the operator was Norsk Hydro, but after transfer of Hydroäs oil assets to Equinor, Equinor took over operatorship. In summer of 2008, Marathon Oil sold its stake to Centrica for $416 million.[4] Total investment has been 19 billion Norwegian krone.

Reservoir

The Heimdal reservoir consists of sandstones from Heimdal Formation. The depth is approximately 2,100 metres (6,900 ft). Recoverable reserves stand at 44.6 billion cubic meter.

Production

The overall rate of processed gas at Heimdal Gas Center constitutes about 15–20% of Norway's total gas export. Three smaller satellite fields Vale, Byggve and Skirne are also connected to Heimdal field via wells on the sea floor.[5]

gollark: You have something which *might become* a child at some point, but isn't.
gollark: I would argue that the child does not actually exist if you abort them early in development.
gollark: Ah, so that's your problem, I see.
gollark: It's not any sort of necessary pain, if a better solution exists which is deliberately not allowed.
