How Iran’s Nuclear Ambitions Shattered Its Oil Industry Dominance

by Arezoo Karimi

Mohsen Qamsari still remembers when Iran’s oil executives were respected at international energy conferences, when major companies competed for contracts, and when Iranian crude moved global markets with every production decision.

Those days are over.

“Everyone up to 30 years ago at important oil seminars was looking to see where Iran’s oil company table was,” said Qamsari, former director of international affairs at the National Iranian Oil Company.

“But unfortunately this is no longer the case. Perhaps we are no longer invited to many seminars at all, or if we are invited, we cannot go.”

His assessment, delivered in a recent interview that gained wide attention on Iranian social media, offers a rare insider’s view of how decades of international sanctions have dismantled Iran’s once-dominant position in global energy markets.

Iran’s oil industry, formerly one of OPEC’s key players and a pillar of the global energy market, now faces what Qamsari describes as unprecedented challenges that have brought about “a collapse of credibility, reduced production capacity, and the loss of Iran’s position in global oil equations.”

The decline contradicts years of official Iranian claims that sanctions have been ineffective.

While government ministers and state media regularly proclaim that Iran has mastered “circumventing sanctions,” Qamsari’s account reveals an industry in crisis, cut off from technology, capital, and customers that once made it a regional powerhouse.

Perhaps no statistic better illustrates Iran’s reduced circumstances than its export profile.

According to recent reports, Iran’s crude oil exports in 2024 totaled about 1.6 million barrels per day, with “almost all” going to China.

This is a dramatic narrowing from the diverse customer base Iran once enjoyed across Europe, Asia, and beyond.

The concentration has strategic implications that became apparent during Iran’s 12-day war with Israel in June.

Unlike previous Middle East crises that sent oil prices soaring, the Iran-Israel war barely affected global markets.

“Even the decision to attack Iran without concern about reduced oil production and price increases has become possible,” Qamsari explained.

The reason: Iranian oil now goes almost exclusively to China’s independent refineries and “plays no role in the countries of the conflict.”

This marks a reversal for a country that in the 1970s could influence global energy policy through production decisions.

Iran’s oil production capacity then matched Saudi Arabia’s and exceeded Iraq’s. Today, surplus capacity in Saudi Arabia and the UAE, combined with non-OPEC supply growth, serves as a buffer against any potential Iranian supply disruption.

Qatar, working with Western and Asian companies, has opened a substantial lead over Iran in developing the shared South Pars gas field.

Iraq, through new contracts with international firms, has boosted daily production above 4.5 million barrels while Iran struggles to return to pre-sanctions levels of 4 million barrels per day.

The isolation extends beyond markets to technology, where Qamsari says Iran has fallen years behind the world’s current technology and knowledge in oil and gas extraction.

In the 1990s and early 2000s, Iran accessed cutting-edge drilling and field development technologies through partnerships with companies like Total, Shell, ENI, and China National Petroleum Corporation.

Today, even Chinese companies have largely withdrawn, forcing Iran to rely on domestic capabilities that lag international standards.

The technological deficit creates a compounding problem. Iran loses an estimated 300,000 barrels per day annually to natural field decline as its aging infrastructure deteriorates.

A report by Middle East Economic Digest said that much of Iran’s production comes from fields active since the 1950s that have technically “matured” and require enhanced recovery techniques to maintain output.

To counter production decline, Iran injects water or gas into reservoirs to increase pressure and extract additional oil.

While such techniques can extend field life, they require sophisticated technology and substantial investment that sanctions have made difficult to obtain.

The cumulative effect means Iran’s oil industry is not only not progressing and hasn’t even remained unchanged, but the passage of each year brings a capacity reduction of 109 million and 500,000 barrels of oil production.

Industry experts estimate Iran needs $200 to $250 billion in investment to rehabilitate and expand its oil infrastructure—figures that require international banking, insurance, and security arrangements that sanctions have made nearly impossible to arrange.

The banking dimension of Iran’s isolation may be the most crippling aspect of the sanctions regime.

Qamsari cites the example of a French bank fined for opening a letter of credit connected to an Iranian institution.

The BNP Paribas case, which resulted in an $8.9 billion penalty, sent shockwaves through the international financial system.

Such precedents have made even eager customers hesitant to deal with Iran. The few transactions that do happen typically involve heavy discounts, payment in goods rather than currency, or acceptance of yuan instead of dollars - all arrangements that reduce Iran’s revenue and limit its financial flexibility.

The risk premium has effectively transformed the National Iranian Oil Company from a global exporter with diverse customers into what Qamsari describes as “a limited and high-risk seller.”

This shift has led to significant reductions in foreign exchange revenues and loss of potential profits that compound Iran’s economic challenges.

Current Iranian oil sales depend heavily on small, non-governmental Chinese refineries willing to accept discounted crude to improve their profit margins.

This concentration creates vulnerability, as any change in Chinese policy or market conditions could severely impact Iran’s primary revenue source.

The economic consequences extend into geopolitical realms that Iranian officials may not fully appreciate.

Before the 1979 Islamic Revolution and in its early aftermath, Iran’s substantial oil market share provided political leverage and even military deterrence.

Other nations hesitated to confront a country whose supply disruption could trigger global energy crises.

Today’s concentrated export pattern eliminates much of that protective effect. Iran’s reduced market presence means its removal would primarily affect Chinese independent refineries rather than major consuming nations, reducing the strategic cost of potential military action against Iranian facilities.

Iran retains substantial theoretical capacity - Qamsari estimates 5 million barrels per day in the absence of sanctions - that could restore its market position and encourage other countries to rebuild relationships.

Russia’s maintenance of international ties despite sanctions partly reflects its continued 14 million barrel daily production that makes other nations reluctant to isolate Moscow completely.

However, achieving such production levels requires exactly the foreign investment and technology access that sanctions prevent.

Without international partnerships, Iran faces continued decline in both production capacity and market influence.

Iranian officials continue to project confidence despite the mounting challenges. Oil Minister Mohsen Paknejad recently said, “We are specialists in circumventing sanctions and we don’t have tied hands.”

Such statements focus narrowly on maintaining some level of oil sales while ignoring broader structural damage to the industry.

The official narrative says sanctions are “ineffective” and celebrates technical achievements compared to pre-revolution capabilities.

Iran’s struggles contrast sharply with regional competitors who have used the same period to strengthen their market positions.

Saudi Arabia has maintained production flexibility that allows it to influence global prices, while the UAE has diversified its energy portfolio and attracted international investment.

Even Iraq, despite ongoing security challenges, has leveraged international partnerships to boost production significantly above Iranian levels.
