Heimdal gas field
Encyclopedia
Heimdal is an offshore natural gas field
in the North Sea
located 212 kilometres (131.7 mi) northwest of the Stavanger
, Norway. Heimdal serves as a connection hub for processing and distribution of natural gas from satellite fields.
The field was discovered in 1972. The depth of the sea at location is 120 metres (393.7 ft). The field was developed with an integrated drilling, production and accommodation facility with a steel jacket
including a riser facility in 1999. 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.
. Partners are Statoil (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 Statoil, Statoil took over operatorship. In summer of 2008, Marathon Oil
sold its stake to Centrica
for $416 million. Total investment has been 19 billion Norwegian krone
.
, Byggve and Skirne
are also connected to Heimdal field via wells on the sea floor.
