Iran’s Oil Sector Can Likely Weather Production Shut-ins, but Gas Fields Are at Risk in Oil & Companies News 04/05/2026 The U.S. blockade of tankers serving Iran’s oil exports is intended to cut Iranian oil exports to near-zero. This would sharply reduce oil export revenues, damage the economy and government budget, and perhaps compel Tehran to make concessions in negotiations, reopen the Strait of Hormuz to free passage, diminish its military power, or even lead to serious internal challenges to the Islamic Republic. A separate analysis has covered the amount of practical oil storage Iran has and how long it can continue producing before needing to reduce output. There is some anticipation that the need to shut-in producing wells and fields will cause damage to facilities, cause them to “explode”, or permanently reduce Iran’s oil production capacity even if and when the blockade is eased. The reality, however, is that Iran has shut in oil production in the past without serious repercussions (as have other oil producers), although gas production may have to be cut back because of the lack of outlets for associated hydrocarbon liquids. That would require rationing of gas between the power, industrial, and residential sectors, as well as exports. An accurate assessment of the risk of shutdowns to Iran’s hydrocarbon production is critical for the diplomatic and military plans of both the United States and Iran, and for understanding the potential future course of the conflict, and the longer-term impacts on the global energy market. Iran’s crude oil production hovered between 3.2-3.3 million barrels per day (bpd) during 2025 and 2026. Crude oil output appears to have dropped somewhat to 3.06 million bpd in March 2026. In addition, Iran derives about 1.3 million bpd of condensate (effectively very light oil) and natural gas liquids (NGLs) from natural gas production. Iran’s refining throughput averaged around 2.1 million bpd pre-war out of a total 2.4 million bpd capacity, and domestic oil consumption averaged about 2 million bpd. Tehran might be able to export small quantities by tankers that evade the U.S. blockade, as well as by trucks and rail. The required production cut to avoid filling storage entirely is therefore up to 50 percent of pre-war levels, the remaining production being refined and used domestically. The country’s hydrocarbon liquid production, broadly defined, comes from four main areas, each with distinct production histories and geological properties. How easily Iran can close down and restart production depends on the characteristics of these areas. Required production cuts can, to some extent, be allocated between fields, and Iran will likely prioritize those fields that have output that can be reduced without serious problems. As the Journal of Petroleum Technology observes, “For the prolific conventional fields in the Middle East, there is very little technical concern about shut-ins and startups.” Indeed, Iranian production rebounded quickly from low levels following the Joint Comprehensive Plan of Action in 2016, and post-Covid in 2023. Iran’s fields do not include most of the cases where production restarts could be difficult: very cold climates (such as Siberia), waxy crudes (such as East Africa), extra-heavy crude (such as Venezuela and Canada), reservoir rocks with swelling clays, fields using chemical or thermal enhanced oil recovery, or hydraulically-fractured shale/tight oil (United States).
