History of Statoil (1972–2007)
The historical record of Norway's state petroleum company from its creation in 1972 through its 2007 merger with Norsk Hydro's oil and gas division.
Last updated August 31, 2026
Overview
Statoil was created by the Norwegian state in 1972 as part of a national strategy to secure public participation in the development of petroleum resources on the Norwegian continental shelf. Its establishment reflected both resource sovereignty and industrial policy: Norway wanted the state to play a direct role in licensing, production, technological development, and the creation of domestic petroleum expertise rather than leaving the emerging North Sea industry entirely to foreign companies. The company was organized as Den Norske Stats Oljeselskap A/S and was required to consult the responsible government ministry on important matters and report annually to the Norwegian Parliament. During its first decades, Statoil expanded beyond exploration and production. It developed interests in petrochemicals and processing, including the Rafsnes facilities and the Mongstad plant, the latter developed in cooperation with Norsk Hydro. In 1981, Statoil became the first Norwegian company to obtain operatorship on the Norwegian continental shelf, taking responsibility for the Gullfaks field. Operatorship strengthened the company's technical and managerial capabilities and helped establish Norway as a significant offshore petroleum center. The company's growth was accompanied by political and environmental controversy. The Mongstad development generated the most serious corporate crisis of the 1980s. Cost and management problems surrounding the project contributed to the 1987–1988 Mongstad scandal and the withdrawal of chief executive Arve Johnsen. Statoil was also affected by industrial action in the North Sea and faced opposition over projects such as its proposed research and development center at Rotvoll in Trondheim. Environmental disputes later focused on exploration in Arctic waters and several reported releases of oil or industrial fluids connected with offshore operations. A major institutional change took place in 2001, when Statoil was converted into a public limited company and partially privatized. Its shares were listed in Oslo and New York, but the Norwegian government remained the controlling shareholder. The change was intended to give the company greater commercial flexibility while preserving national influence over a strategically important enterprise. Statoil subsequently became a major crude-oil trader and an important supplier of natural gas to continental Europe. It also operated a substantial international network of service stations, reported in the period as numbering about 2,000 sites across nine countries. The company encountered a major reputational crisis in the early 2000s when Norwegian reporting exposed payments to Horton Investments, an Iranian consultancy connected to Mehdi Hashemi Rafsanjani. The payments were investigated as an attempt to obtain influence and secure petroleum contracts in Iran, producing a corruption case that became one of Statoil's most prominent controversies. In December 2006, Statoil proposed combining with Norsk Hydro's oil and gas operations. The transaction received European Union approval in May 2007 and Norwegian parliamentary approval in June. It was completed on 1 October 2007. Statoil shareholders received 67.3 percent of the successor company, StatoilHydro, while the transaction created a larger Norwegian offshore petroleum group. The historical period covered by this article therefore ends with the disappearance of the original standalone Statoil company, although the Statoil name continued through the successor and was restored in 2009 before the later adoption of the Equinor name.
History
The Norwegian state founded Den Norske Stats Oljeselskap A/S on 14 July 1972 through a unanimous act of the Storting. The company was created during the early development of Norway's offshore petroleum sector. Its mandate was not limited to commercial production: Statoil was also intended to ensure Norwegian participation in the continental shelf, develop national competence, and provide the foundations of a domestic petroleum industry. Important corporate matters had to be discussed with the responsible minister, and the company was accountable to Parliament through annual reporting. Statoil developed a broad petroleum business during the 1970s and 1980s. It entered petrochemicals and helped develop processing infrastructure at Rafsnes and Mongstad. The Mongstad facility was developed with Norsk Hydro and became strategically important, but later generated severe cost and management controversy. In 1981, Statoil achieved a landmark institutional and technical milestone by becoming the first Norwegian company to operate a field on the Norwegian continental shelf, Gullfaks. This role gave the company direct experience in managing complex offshore projects and reinforced Norway's position as a petroleum-producing nation with indigenous operating capabilities. The Mongstad crisis of 1987–1988 was a defining setback. The controversy became the largest scandal in the company's history at that time and resulted in chief executive Arve Johnsen withdrawing from the position. Statoil also experienced labor disruption in the North Sea and encountered organized environmental resistance. The Rotvoll dispute in Trondheim concerned plans for a research and development center in a wetlands area valued for birdlife. Although activists from environmental organizations engaged in civil disobedience, the facility was ultimately built. In 2001, Statoil underwent partial privatization and became Statoil ASA, a public limited company listed in Oslo and New York. The Norwegian state maintained majority ownership, preserving political influence while giving the company a more commercial corporate structure. By this period Statoil had become a major international petroleum enterprise. It was a significant crude-oil seller, a major supplier of natural gas to Europe, and an operator of roughly 2,000 service stations in nine countries according to the historical reference. The early 2000s also brought environmental and compliance controversies. Exploration in Arctic waters near Norway was opposed by environmental groups concerned about the vulnerability of the region. The reference history records several releases associated with offshore activity, including a large North Sea spill in December 2007 after the merger and additional leaks in 2008. Because those latter events occurred after the original Statoil period, they belong to the wider StatoilHydro-era record rather than strictly to the 1972–2007 standalone chronology. Another major controversy involved Iran. In 2002 and 2003, Statoil paid Horton Investments, an Iranian consultancy associated with Mehdi Hashemi Rafsanjani, in an effort described as seeking political influence and access to oil contracts. Norwegian newspaper Dagens Næringsliv reported the matter in September 2003, turning it into a prominent corruption scandal and damaging the company's reputation. Statoil's standalone existence ended through a strategic combination with Norsk Hydro's oil and gas division. The proposal was announced in December 2006, approved by the European Union in May 2007 and by the Norwegian Parliament in June 2007, and completed on 1 October 2007. Former Statoil shareholders held 67.3 percent of StatoilHydro. The successor retained the Statoil name for a time, changed its name back to Statoil in 2009, and later adopted the Equinor name. The article represented by this dossier therefore concerns the original state petroleum company and its transformation into the larger post-merger enterprise.
