The Heidrun field is located on Haltenbanken, off the coast of mid-Norway. The oil from the field is primarily transported by oil tanker to Statoil's Mongstad terminal in Hordaland County. The gas from Heidrun is transported by pipeline to Tjeldbergodden in Møre and Romsdal County, and also via Åsgård Transport to the Kårstø terminal north of Stavanger.
Oil and gas production at the Heidrun field started in 1995. Statoil has been the operator since then.
The field was, however, discovered by Conoco in 1985, and Conoco was the development operator until production start-up, when the operatorship was transferred to Statoil. The field was developed using a concrete tension leg platform at a water depth of 350 meters.
ConocoPhillips' ownership in Heidrun is 24.08 percent.
