Heidrun - oil and gas field in the Norwegian Sea - Equinor
Heidrun is a field on Haltenbanken in the Norwegian Sea, 30 kilometres northeast of the Åsgard field. The water depth is 350 metres.

Located about 175 kilometres off the coast of Mid-Norway in some 350 metres of water, the Heidrun field development concept includes the world’s largest floating concrete tension-leg platform. Our first field on stream in the Norwegian Sea Heidrun has been producing oil and gas since October 1995. Heidrun was discovered in 1985 by Conoco, the operator in the exploration and development phase. The field has already delivered oil volumes far beyond initial expectations for the field’s total productive life. When the plan for development and operation (PDO) was submitted to the authorities in 1991, total production was estimated at slightly more than 750 million barrels of oil. Our ambition is to increase the reserves from the current 1.260 to 1.890 billion barrels of oil and gas. Producing almost 250,000 barrels of oil per day in the peak period, Heidrun’s current production is around 60,000 barrels. The platform is a combined production and drilling platform. In addition, Heidrun has a dedicated well intervention tower for well workover activites. In June 2015 the new floating storage vessel Heidrun B received the first barrels of oil from the Heidrun field. The vessel is designed to be permanently moored for at the Heidrun platform, in one of the harshest offshore environments in the world, for at least 30 years. Heidrun is a demanding field, with great challenges associated with sand production, scale and tough corrosion conditions in the wells. Both water and gas are now being injected to maintain the pressure in the reservoir and enhance recovery, and the use of both is being continuously optimised. New wells are almost continuously drilled from the platform to maintain production. Efficient, inexpensive drainage points are essential to extending the field’s ultimate productive life. More than 100 wells have been drilled on the field so far, and almost the same number will be drilled before the field is shut down. The northern flank of Heidrun was put on stream in August 2000. The partners in the Heidrun licence have invested some NOK 600 million in a reinjection plant for produced water on the Heidrun platform. Consequently, water, and any oil or chemical residues it contains, that was previously discharged into the sea is now reinjected into the reservoir. The result is zero harmful discharge
