Overview
The Iraq Petroleum Company (IPC) was a British-registered petroleum enterprise that played a central role in the discovery, development, and export of Iraqi oil. It originated as the Turkish Petroleum Company (TPC), an early twentieth-century consortium formed around the expectation that Mesopotamia contained substantial petroleum reserves. The venture brought together British, German, Dutch, French, American, and Armenian interests and reflected the close relationship between oil concessions, imperial diplomacy, railway development, and international competition for energy resources. TPC’s early plans were disrupted by the First World War and the collapse of the Ottoman Empire. After the war, the disposition of German interests in the former Ottoman territories became an international diplomatic issue. At the 1920 San Remo Conference, the French acquired the former German participation, while the United States pressed for an “open door” policy that would allow American oil companies to participate. A concession granted by the Iraqi government in 1925 covered the Baghdad and Mosul provinces and required the consortium to survey the territory, drill exploratory wells, and develop production. The arrangement also included royalty obligations and provisions concerning Iraqi representation and employment, although it became politically controversial within Iraq. Exploration accelerated during the middle of the 1920s. On 14 October 1927, TPC struck oil at Baba Gurgur near Kirkuk. The discovery demonstrated the scale of the northern Iraqi reserves and intensified negotiations over the consortium’s final ownership. In 1928, the partners formalized a structure in which Anglo-Persian Oil Company, Royal Dutch Shell, Compagnie Française des Pétroles, and the American Near East Development Corporation each held 23.75 percent, while Calouste Gulbenkian retained 5 percent. The consortium was reorganized as the Iraq Petroleum Company, a non-profit-style production company intended to supply crude to its parent companies rather than compete with them in international refining and marketing. IPC’s influence extended beyond its Iraqi concession. Through the related Iraq Petroleum Group and associated development companies, the shareholder interests participated in petroleum exploration and infrastructure projects across parts of the Middle East. The company built or supported pipelines, field installations, transport systems, and export facilities connecting Iraqi production to Mediterranean ports. Its operations helped make Kirkuk one of the major oil-producing areas of the region and contributed to the emergence of Iraq as an important petroleum state. For decades, IPC possessed a near-monopoly over oil exploration and production in Iraq. Its concession arrangements, ownership structure, and control of infrastructure gave it considerable leverage over the pace and terms of development. The company’s position was increasingly challenged by Iraqi nationalists and governments seeking greater control over natural resources and a larger share of petroleum revenues. In 1961, Iraq passed legislation limiting the company’s concession rights, and the company’s effective operating position deteriorated. The Ba'athist government nationalized IPC in June 1972, transferring its operations to the Iraq National Oil Company. IPC subsequently ceased to have an operating role, although the corporate entity has been described as continuing in paper form. Its history remains significant both for Iraqi petroleum development and for the wider history of international oil concessions and resource nationalism.
History
The company’s origins lay in the Turkish Petroleum Company, established before the First World War by interests associated with Calouste Gulbenkian, the National Bank of Turkey, Deutsche Bank, and Anglo-Saxon Petroleum, the Shell affiliate. The proposed enterprise sought access to Mesopotamian oil while the Ottoman Empire still controlled the territory. British naval interest in petroleum and the strategic importance of the Berlin–Baghdad railway helped draw the British government and Anglo-Persian Oil Company into the negotiations. A 1914 agreement redistributed ownership among British, German, and Shell interests and included the basic principles later associated with the Red Line arrangement. The war halted the company’s original plans. After the Ottoman Empire was dismantled, the future of its petroleum concessions became part of the postwar settlement. The 1920 San Remo Oil Agreement transferred the former German participation to France and provoked American criticism that U.S. companies were being excluded from Middle Eastern resources. Subsequent diplomatic negotiations eventually permitted American participation through the Near East Development Corporation. In 1925, the Iraqi government granted TPC a large concession covering the Baghdad and Mosul provinces. The concession imposed exploration and drilling commitments, required payment of royalties, and included provisions relating to Iraqi representation and employment. TPC established exploration bases, roads, water lines, rail connections, and drilling infrastructure. On 14 October 1927, a well at Baba Gurgur near Kirkuk struck oil at approximately 1,521 feet. The discovery was initially difficult to control but confirmed that northern Iraq held major petroleum reserves. The discovery accelerated negotiations among the consortium’s shareholders. In 1928, Anglo-Persian Oil Company, Royal Dutch Shell, Compagnie Française des Pétroles, the Near East Development Corporation, and Gulbenkian agreed on the ownership structure that underpinned the renamed Iraq Petroleum Company. Each of the four corporate groups held 23.75 percent, while Gulbenkian held 5 percent. The Red Line Agreement restricted the partners’ ability to compete independently in much of the former Ottoman Middle East and shaped the geography and pace of regional petroleum development. IPC was organized primarily as a producer of crude for its parent companies. Its ability to refine and sell petroleum internationally was limited by the corporate arrangements, although it could serve Iraq’s domestic market. The company and its associated enterprises developed oil fields, pipelines, pumping stations, and export routes. The Iraq Petroleum Group also became involved in related concessions and development companies outside Iraq, extending the shareholders’ regional reach. The company’s dominance generated both economic importance and political opposition. IPC’s concession represented a major channel through which foreign companies controlled Iraqi petroleum, while Iraqi governments and nationalist movements sought higher revenues, greater employment and participation, and eventual sovereignty over natural resources. In 1961, Iraq adopted legislation designed to reduce IPC’s concession area and limit its remaining rights. The company’s practical role was ultimately ended by nationalization in June 1972, when the Ba'athist government transferred its operations to the Iraq National Oil Company. IPC is generally treated as an inactive historical operator, although the legal entity has been reported as surviving in paper form. Its associated Abu Dhabi Petroleum Company was a separate enterprise that retained the historical shareholding pattern of the Iraq Petroleum Group.

Products and positioning
A historically dominant international oil-concession operator focused on upstream exploration, production, and export infrastructure in Iraq.
Upstream petroleum
Iraqi crude oil
IPC’s principal output was crude oil produced from Iraqi fields, especially the large Kirkuk-area resources discovered and developed during the company’s operating period. The company was structured mainly to produce crude for its shareholder companies rather than to operate as a consumer-facing fuels brand.
Petroleum services and operations · 1925
Oil exploration and field development
The company conducted geological surveys, exploratory drilling, reservoir development, and construction of field infrastructure. Its work transformed Iraqi petroleum prospects into a large-scale commercial production system.
Energy infrastructure
Pipeline and export infrastructure
IPC and associated companies developed pipelines, pumping facilities, transport links, and export arrangements to move Iraqi crude toward Mediterranean outlets. These assets were essential to converting inland oil discoveries into internationally traded production.
