About this data

Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Licences and shares are the current rows of each licence's and field's licensee history. Production is the saleable volume of the fields the company operates, the whole field, over the twelve months ending in the latest month any field has reported. Wellbores are those naming the company as drilling operator; a renamed or merged company is a separate record from its predecessor. Register messages are matched on the company's name.
