How did the Iran-Iraq War damage Iran's oil and petrochemical industries?

During the Iran-Iraq War, Iran’s oil and petrochemical industries suffered significant damage due to direct military strikes and the disruption of export infrastructure. Both nations engaged in sporadic air and missile attacks against each other's oil installations throughout the conflict.1

Key impacts included:

• Targeting of Infrastructure: Iraqi forces frequently targeted critical facilities, such as the oil terminal at Kharg Island, which forced Iran to shift its shipping operations to smaller, less efficient facilities at Lavan and Sirri islands.2
• The Tanker War: Beginning in 1984, both countries attacked oil-tanker shipping in the Persian Gulf. This Tanker War involved strikes on more than 100 tankers, severely reducing Iran's oil-exporting capacity.13
• Economic Consequences: The combination of air strikes and pipeline shutoffs led to a sharp reduction in oil income and foreign-currency earnings. This loss of revenue brought Iran's economic development programs to a near standstill.1

While the city of Abadan—a major oil-refining center—was a primary target of early Iraqi offensives, it remained a focal point of the conflict's destructive impact on Iran's energy sector.4
