Iran holds 157 billion barrels of proven oil reserves, ranking 4th globally and accounting for 9% of total supply. Plans for $120B investment aim to boost

Iran possesses approximately 157 billion barrels of proven oil reserves, making it the world's fourth-largest holder and accounting for roughly 9% of global reserves as of late 2024 [3]. This vast resource, concentrated in "super-fields" like Azadegan, which alone holds an estimated 38 billion barrels, positions Iran as a major energy power, though its full potential remains constrained by international sanctions [3].

## Iran's Untapped Oil Wealth

Iran's proven reserves of 157 billion barrels could supply global demand for nearly four years at an average consumption rate of 100 million barrels per day [3]. Geologists estimate the total recoverable reserves could exceed 200 billion barrels with advanced extraction technologies, as many areas in the Persian Gulf and central desert remain underexplored [3]. The country's oil is predominantly light crude with low sulfur content, making it easier to refine, and extraction costs are competitive, ranging from $12-13 per barrel [3].

Despite these advantages, Iran's oil sector has been hampered by prolonged international sanctions, which have limited access to advanced extraction technology [3]. Currently, the oil recovery rate at many Iranian fields is around 27%, meaning 73% of the oil remains underground due to a lack of modern pumping and management systems [3]. Sanctions have also restricted international payments and shipping insurance, leading to significant fluctuations in export volumes and impacting government revenue [3].

## Future Outlook and Investment Plans

In 2025, Iran's Ministry of Oil announced a strategy to revitalize the oil and gas industry, planning investments of up to $120 billion for exploration, expansion, and technological upgrades [3]. The goal is to increase daily oil production from approximately 3.1 million barrels to 4.8 million barrels by 2030 [3]. Iran is also seeking technical cooperation with non-Western partners, particularly in drilling equipment, digital field monitoring, and enhanced oil recovery (EOR) technologies [3]. Improving the recovery rate to levels comparable with other Gulf nations could significantly boost global oil supply in the medium to long term [3].

## What to watch

*   **Sanctions developments:** Any easing of international sanctions could rapidly increase Iran's oil exports and impact global supply-demand dynamics [3].
*   **Investment execution:** Progress on Iran's $120 billion investment plan and its impact on extraction technology adoption and production targets by 2030 [3].
*   **Geopolitical stability:** Escalating tensions in the Persian Gulf could disrupt supply, while de-escalation could facilitate increased Iranian output [3].

Iran's substantial, yet underutilized, oil reserves represent a significant factor in global energy markets, with any shift in its production capacity or export accessibility poised to influence oil prices and supply balances.
