Thorleif Enger (born 31 October 1943) is a Norwegian businessperson and was Chief Executive Officer of Yara International.
[2] Enger has been president of the International Fertilizer Industry Association,[3] and has been a chairman or non-executive director of several boards, including Telenor, Spring Energy, HitecVision, and Marine Harvest.
In 2010, Kapital named him one of the top ten business leaders in Norway after World War II.
[5] Enger was selected to be asset manager for the giant Oseberg field in the North Sea which at the time was the largest offshore project in the world.
Troll Oseberg Gas Injection (TOGI) was controversial, but it turned out to be a commercial and technical success.
[12] During this period the Hydro Oil and Gas business increased substantially by adding a number of fields to its North Sea portfolio.
Fields where Norsk Hydro was the operator included Oseberg, Brage, Njord, and Troll oil.
[19] In 2005 the Yara Prize was initiated and awarded to people having made outstanding contributions to the development of Agriculture in Africa.
This was highly appreciated and successful, and the Oslo award ceremonies and conferences in Oslo were attended by leading people in the field including the Nobel Prize winner Norman Borlaug, Jeffrey Sachs, Kofi Annan, as well as leading African politicians.
