Career
Shell Enger was employed at Royal Dutch Shell's Houston office from 1970 to 1973 where he worked on an LNG-project. This project was innovative in the sense that it used gas injection from Troll. Troll Oseberg Gas Injection (TOGI) 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. 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.
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.
After Yara Enger was member of the Business Advisory Group to the Africa Progress Panel.
Board memberships, awards, published books 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.
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. Enger was declared innocent in 2016, and received compensation for being wrongly accused.
