The field lies 175 kilometres (109 mi) north of Kristiansund. It has produced oil and gas since October 1995. In 2013, it produced 65,000 barrel of oil per day and 760 million cubic meters of natural gas.^[1] The crude oil is characterized as being naphthenic with 25.0 API (0.9043 g/cm³), 0.52% sulfur, and a high TAN (Total Acid Number) of 2.90.

The Heidrun field is located on Haltenbanken in the Norwegian Sea at a depth of 350 metres (1,150 ft). The field has been developed with gas and water injection, using a floating concrete tension leg platform, installed over a subsea template with 58 well slots.^[2] The northern part of the field is developed with subsea facilities.
