Heimdal is a gas field west of Sveio in Hordaland county, in the northern part of the North Sea, north of Johan Sverdrup and south of Oseberg, near the border with the UK shelf.
Current Heimdal partners are Equinor (29.4% - operator), Petoro (20.0%), Total E&P Norge (16.7%), Spirit Energy (28.8%) and LOTOS Exploration and Production (5.0%).
The Heimdal field was discovered in 1972, and production started in 1986. French oil company Elf was the operator from start-up.
The development of Heimdal, together with gas exports from Statfjord and Gullfaks, formed the foundation for establishing Statpipe, the cornerstone in the Norwegian gas transport system.
As of January 2019, a total of 46 billion Sm3 of gas and 7 million Sm3 of oil have been produced from the Heimdal field.
After most of the gas reserves in the actual Heimdal reservoir had been produced towards the end of the 1990s, the field was modified to receive and process gas from the Huldra, Vale and Byggve/Skirne fields. Gas from Atla and Valemon was subsequently added. Operatorship was transferred to Norsk Hydro in connection with the reconstruction to a gas processing centre.
Together with gas from Valemon, Skirne, Atla, Heimdal and Vale, gas from the Oseberg Gas Transport system (OGT) is divided between the Statpipe and Vesterled pipelines and distributed onwards to the European continent and the UK. Condensate from processed gas on Heimdal will be sent by pipeline to the Brae platform in the UK sector. It will go from there to the Forties Pipeline System, and further on to land facilities in the UK.
In connection with tie-in of the new fields for gas processing and gas transit, a riser platform was installed in 2000 and tied into the main platform from 1985. Today, the riser platform is owned by Gassled and Gassco is the operator.
