ConocoPhillips Norway

Fields Operated By Others

ConocoPhillips has interests in fields operated by co-venturers - fields that are on stream and constitute a considerable part of the company's asset portfolio on the Norwegian continental shelf. Heidrun, Visund, Oseberg, Grane, Troll, Alvheim and Huldra are among these fields.

ConocoPhillips is also a partner in the Aasta Hansteen gas field, which is under development. Planned started-up in late 2018/early 2019.


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 He​idrun 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.
