The economy of Iraq is dominated by the oil sector, which has provided about 99.7% of foreign exchange earnings during its modern history. As of 2021, the oil sector provides about 92% of foreign exchange earnings. Iraq's hitherto agrarian economy underwent rapid development following the 14 July Revolution which overthrew the Hashemite Iraqi monarchy. It had become the third-largest economy in the Middle East by 1980. This occurred in part because of the Iraqi government's successful industrialization and infrastructure development initiatives in the 1970s, which included irrigation projects, railway and highway construction, and rural electrification.
The Organization of the Petroleum Exporting Countries is a cartel of 13 countries. Founded on 14 September 1960 in Baghdad by the first five members, it has, since 1965, been headquartered in Vienna, Austria, although Austria is not an OPEC member state. As of September 2018, the 13 member countries accounted for an estimated 44 percent of global oil production and 81.5 percent of the world's proven oil reserves, giving OPEC a major influence on global oil prices that were previously determined by the so-called "Seven Sisters" grouping of multinational oil companies.
The Rumaila oil field is a super-giant oil field located in southern Iraq, approximately 20 mi (32 km) from the Kuwaiti border. Discovered in 1953 by the Basrah Petroleum Company (BPC), an associate company of the Iraq Petroleum Company (IPC), the field is estimated to contain 17 billion barrels, which accounts for 12% of Iraq's oil reserves estimated at 143.1 billion barrels. Rumaila is said to be the largest oilfield ever discovered in Iraq and is considered the third largest oil field in the world.
The South Pars/North Dome field is a natural-gas condensate field located in the Persian Gulf. It is by far the world's largest natural gas field, with ownership of the field shared between Iran and Qatar. According to the International Energy Agency (IEA), the field holds an estimated 1,800 trillion cubic feet of in-situ natural gas and some 50 billion barrels of natural gas condensates. On the list of natural gas fields it has almost as much recoverable reserves as all the other fields combined. It has significant geostrategic influence.

Proven oil reserves in Iran, according to its government, rank fourth largest in the world at approximately as of 2013, although it ranks third if Canadian reserves of unconventional oil are excluded. This is roughly 10% of the world's total proven petroleum reserves. At 2020 rates of production, Iran's oil reserves would last 145 years if no new oil was found.
As of 2005, Azerbaijan produced a range of metals and industrial minerals, including aluminum, lead, iron, and zinc.
The proven oil reserves in Saudi Arabia are reportedly the second largest in the world, estimated in 2017 to be 268 billion barrels, including 2.5 Gbbl in the Saudi–Kuwaiti neutral zone. This would correspond to more than 50 years of production at current rates. In the oil industry, an oil barrel is defined as 42 US gallons, which is about 159 litres, or 35 imperial gallons. The oil reserves are predominantly found in the Eastern Province. These reserves were apparently the largest in the world until Venezuela announced they had increased their proven reserves to 297 Gbbl in January 2011. The Saudi reserves are about one-fifth of the world's total conventional oil reserves. A large fraction of these reserves comes from a small number of very large oil fields, and past production amounts to 40% of the stated reserves.
The proven oil reserves in Venezuela are recognized as the largest in the world, totaling 300 billion barrels (4.8×1010 m3) as of 1 January 2014. The 2019 edition of the BP Statistical Review of World Energy reports the total proved reserves of 303.3 billion barrels for Venezuela (slightly more than Saudi Arabia's 297.7 billion barrels).
There have been widely varying estimates of proven oil reserves in Russia. Most estimates included only Western Siberian reserves, which have been exploited since the 1970s and supply two-thirds of Russian oil. However, there are potentially huge reserves elsewhere. In 2005, the Russian Ministry of Natural Resources estimated that another 4.7 billion barrels of oil exist in Eastern Siberia. In July 2013, the Russian Natural Resources Ministry made official estimates of reserves available for the first time. According to Russian Natural Resources Minister Sergey Donskoy, as of 1 January 2012, recoverable reserves of oil in Russia under category ABC1 were 17.8 billion tons and category C2 reserves were 10.9 billion tons.
Oil reserves in Libya are the largest in Africa and among the ten largest globally with 46.4 billion barrels as of 2010. Oil production was 1.65 million barrels per day as of 2010, giving Libya 77 years of reserves at current production rates if no new reserves were to be found. Libya is considered a highly attractive oil area due to its low cost of oil production, low sulfur content, being classified as "sweet crude" and in its proximity to European markets. Libya's challenge is maintaining production at mature fields, while finding and developing new oil fields. Most of Libya remains under-explored as a result of past sanctions and disagreements with foreign oil companies.
Energy in Saudi Arabia involves petroleum and natural gas production, consumption, and exports, and electricity production. Saudi Arabia is the world's leading oil producer and exporter. Saudi Arabia's economy is petroleum-based; oil accounts for 90% of the country's exports and nearly 75% of government revenue. The oil industry produces about 45% of Saudi Arabia's gross domestic product, against 40% from the private sector. Saudi Arabia has per capita GDP of $20,700. The economy is still very dependent on oil despite diversification, in particular in the petrochemical sector.

Iran is an energy superpower and the petroleum industry in Iran plays an important part in it. In 2004, Iran produced 5.1 percent of the world's total crude oil, which generated revenues of US$25 billion to US$30 billion and was the country's primary source of foreign currency. At 2006 levels of production, oil proceeds represented about 18.7% of gross domestic product (GDP). However, the importance of the hydrocarbon sector to Iran's economy has been far greater. The oil and gas industry has been the engine of economic growth, directly affecting public development projects, the government's annual budget, and most foreign exchange sources.
Iraq was the world's 5th largest oil producer in 2009, and has the world's fifth largest proven petroleum reserves. Just a fraction of Iraq's known fields are in development, and Iraq may be one of the few places left where vast reserves, proven and unknown, have barely been exploited. Iraq's energy sector is heavily based upon oil, with approximately 94 percent of its energy needs met with petroleum. In addition, crude oil export revenues accounted for over two-thirds of GDP in 2009. Iraq's oil sector has suffered over the past several decades from sanctions and wars, and its oil infrastructure is in need of modernization and investment. As of June 30, 2010, the United States had allocated US$2.05 billion to the Iraqi oil and gas sector to begin this modernization, but ended its direct involvement as of the first quarter of 2008. According to reports by various U.S. government agencies, multilateral institutions and other international organizations, long-term Iraq reconstruction costs could reach $100 billion (US) or higher.
Iraq's large oil reserves have attracted attention from the United Kingdom, a country with a high demand for oil. British involvement in the Iraqi oil industry dates to World War I. Political influence in the region has given the UK the power to establish a number of oil companies in Iraq.
