Enger was born 31 October 1943. He is the brother of Ole Enger, former CEO of REC, and now chairman of REC Solar. They grew up on a farm in Øvre Eiker. Thorleif Enger earned his PhD in Structural Engineering from the University of Colorado.
Shell
Enger was employed at Royal Dutch Shell’s Houston office from 1970 to 1973 where he worked on an LNG-project.
Norsk Hydro Oil and Gas
Oseberg
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. Oseberg was the first operatorship of Norsk Hydro. The project was completed within time and on budget. At its peak the production was 500,000 barrels per day. This project was innovative in the sense that it used gas injection from Troll. Troll Oseberg Gas Injection was controversial, but it turned out to be a commercial and technical success.
Head of Hydro Exploration and Production
Enger became head of Hydro Exploration and Production due to his handling of the Oseberg project. He was head of E&P from 1987 to 1996. 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. During this period Norsk Hydro production operatorship went from zero to roughly 1 million barrels per day. The portfolio also included E&P activities in Russia, UK, Maghreb and Angola.
Head of Hydro Oil and Gas
Enger was head of Hydro Oil and Gas from 1996 to 1999. NORSOK was an initiative made by the Norwegian government to tackle cost overruns on the Norwegian Continental Shelf. It was led by Enger, and is considered to be successful although its ambitious targets were not fully met.
Norsk Hydro Agri
Hydro Agri, the agricultural division of Norsk Hydro had for quite some time delivered unsatisfactory results and a turnaround operation was initiated in 1999 when Enger became head of the organization. During a 3-year period the business went through a big transition selling off non-core business, closing unprofitable plants and markets and reducing fixed costs and manning by more than 30%.
Yara
Yara was spun out of Norsk Hydro and became a listed company in the spring of 2004. Since then, the market capitalization of the company increased several fold reaching about 100 billion NOK and being one of the largest companies on the Oslo Stock Exchange. Yara is one of the largest suppliers of fertilizer in the world with a presence on all continents. Enger resigned as CEO in 2008.
Yara Prize
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.
Enger has been chairman of Telenor, Spring Energy, Agrinos, Green Energy Group, and Treka, and he has been a board member of HitecVision, FMC Technologies, Marine Harvest, Acergy, PGS, Kverneland, NGI, and the supervisory board of E.ON Ruhrgas. He was elected Norway’s SPE Oilman of the Year in 1996, and selected by the business magazine Kapital in 2010 as one of the 10 best business leaders in Norway after World War II. Enger’s book ”Det handler om å bli best” was published in 2012.
Lawsuit
In 2014, Enger was alongside two former colleagues in Yara charged with two counts of corruption. The case is unique in the sense that Enger has declared himself innocent whilst the company, Yara, has declared itself guilty.
Personal life
Enger is married to an American and has two children.
