Overview
The Iraq National Oil Company (INOC) was an Iraqi state petroleum company established by the government in 1966 to assume control of much of the country's oil industry. Its creation followed Iraq's increasingly assertive resource policy after Public Law 80 of 1961 removed approximately 95 percent of the Iraq Petroleum Company's concession area. The Iraqi government announced its intention to establish a national oil company in 1964, and the resulting organization was given a broad mandate covering exploration, development, production, transport, and other upstream and midstream activities. Refining remained under the Oil Refineries Administration, while domestic distribution was already handled separately by the state. INOC was designed as an instrument of national control rather than as a conventional commercial partner for international oil companies. Unlike the model used by some other national oil companies, it was initially prohibited from entering partnerships with foreign oil companies or granting foreign concessions. Its remit expanded in 1967 and 1968 to include additional areas taken from the Iraq Petroleum Company. Iraq also secured Soviet technical and financial assistance through the Iraq-Soviet Protocol of 1967, which helped support the company's development capacity. One of INOC's most important operating achievements was the development of the North Rumaila oil field. Although discussions had taken place about involving Compagnie Française de Pétroles, an Iraq Petroleum Company participant associated with the field's earlier concession arrangements, the project was ultimately advanced with Soviet assistance. INOC opened North Rumaila on 7 April 1972. That same year, the nationalization of Iraq's oil industry was completed, giving the company a central role in the country's petroleum system. During the period in which it exercised broad control, INOC contributed to a substantial increase in Iraqi oil production. Production rose from approximately 1.4 million barrels per day in the company's early period to more than 3 million barrels per day by 1980. The Iran-Iraq War, which began in 1980, then severely damaged Iraq's production capacity and disrupted operations, particularly in the south and around export infrastructure. INOC's institutional independence ended in 1987. Decree 267 merged the company into Iraq's Ministry of Oil under the direction of newly appointed oil minister Asfhaq ul Rasheed. The ministry became both the industry's direct operator and its regulator, while the former unified national company was reorganized into regional operating entities. The largest successor organizations included North Oil Company, headquartered in Kirkuk, and South Oil Company, based in Basra. INOC therefore survives primarily as a historical name associated with Iraq's nationalization of petroleum resources, rather than as an active standalone corporate brand.
History
The origins of INOC lay in Iraq's effort to reclaim control over petroleum resources previously covered by the Iraq Petroleum Company's concessions. In 1961, Iraq enacted Public Law 80, which expropriated approximately 95 percent of the company's concession area. The government announced plans for a national oil company in 1964 and formally established the Iraq National Oil Company in 1966. The company's mandate was broad. It was authorized to conduct most activities associated with Iraq's oil industry, while refining remained the responsibility of the Oil Refineries Administration, created in 1952, and local petroleum distribution remained under separate government control. INOC was intended to be a national operating institution, not merely a regulatory holding company. Its authority expanded in 1967 and 1968 as additional areas taken from the Iraq Petroleum Company were brought within its remit. A defining feature of the original model was its restriction on foreign participation. INOC could not enter partnerships with foreign oil companies or issue concessions to them. This policy reflected Iraq's objective of exercising direct sovereign control over production and development. There was discussion of involving Compagnie Française de Pétroles in developing the North Rumaila field because of its former relationship with Iraq Petroleum Company arrangements, but no such foreign operating partnership ultimately became the basis for the project. Instead, Iraq turned to the Soviet Union. The Iraq-Soviet Protocol signed in 1967 provided technical and financial assistance, strengthening INOC's ability to develop fields without returning to the concession structure that Iraq had rejected. With Soviet help, the company opened North Rumaila on 7 April 1972. The event was particularly important because it demonstrated that Iraq could place a major oil asset into production under national control. Oil nationalization was completed in 1972. During the following years, INOC managers increased national production from about 1.4 million barrels per day in the company's early period to more than 3 million barrels per day by 1980. This expansion established INOC as one of the central institutions of the Iraqi economy and as the principal vehicle for operating the country's nationalized oil assets. The Iran-Iraq War, which began in 1980, severely affected production capacity and operating conditions. Damage and disruption to oil fields, export routes, and related infrastructure reduced the effectiveness of the system that INOC had built. The company continued to exist until 1987, when Decree 267 merged it with the Ministry of Oil. Under the new arrangement, the ministry became both regulator and direct operator. INOC's unified national structure was replaced at the operational level by regional companies, most prominently North Oil Company in Kirkuk and South Oil Company in Basra. The former company is therefore best understood as a historical state enterprise whose functions were redistributed within Iraq's oil administration.

Products and positioning
A state-controlled national oil company established to consolidate Iraqi control over petroleum resources and reduce the role of foreign concession holders.
Upstream petroleum · 1966
Crude oil production
Crude oil exploration, field development, and production formed the core of INOC's activity. The company was created to place Iraq's petroleum resources under direct state management and expanded its operating territory as former Iraq Petroleum Company concession areas were brought under national control. Its development of North Rumaila was the clearest example of this mandate.
Midstream petroleum · 1966
Oil transportation and related operations
INOC's mandate covered petroleum activities beyond field production, including related transportation and operational functions. Refining was excluded because it was already assigned to the Oil Refineries Administration, and local distribution was separately controlled by the Iraqi government. These boundaries made INOC primarily an exploration, production, and associated oil-industry operating company.
