Provided by Advokatfirmaet Thommessen AS
Thommessen is one of Norway's leading oil and gas law firms, and has been engaged as advisers within the industry ever since the dawn of Norway's oil age.
We have assisted in connection with all the major structural changes and transactions on the Norwegian continental shelf. Our lawyers have been involved in everything from the restructuring of the State's ownership interests on the Norwegian continental shelf and the privatisation and listing of Equinor to the merger of Equinor's and Hydro's oil and gas activities. We have also been heavily involved in recent years' transactions resulting from established international players turning their focus to other geographies.
Our oil and gas team assists oil companies, suppliers, public authorities, investment banks and investors. We provide advice at all stages of a project, regardless of size, scope or legal area – from idea to delivery or from incorporation to sale or listing. With our in-depth understanding of the industry and long experience in all areas of expertise, we are able to provide practical and commercially sound advice.
