战前，伊朗每天生产约300万桶（约47.7万立方米）原油，另有75万桶（约11.9万立方米）凝析油；国内需求接近190万桶（约30.2万立方米）/日，故可新增出口余量约185万桶（约29.4万立方米）/日。即使封锁已持续两周，Kharg Island仍持续将原油装载到已在波斯湾的油轮。Kpler估计伊朗仍有12到22天可用储存量，远高于美国初始预期；到5月中旬，当储存接近上限时，产量可能较战前水平下降约一半。
历史经验明显削弱了“不可逆损伤”的叙事。2019至2020年在重压制裁中，伊朗曾显著减产，之后重启产量，并在2025年重回46年高点。工程人员可透过逐步节流、轮换关停油田、避免进水等方式缓冲，故停产数周到数月通常可恢复。具伊朗实务经验的石油顾问Robin Mills认为，若封锁放宽，伊朗大机率可在数个月内回到约70%战前产能，且大部分产能可逐步恢复。封锁仍将加剧经济压力并推高未来恢复成本，但其主要作用是谈判杠杆，而非立即造成技术性毁灭。
Donald Trump has argued since April 26 that Iran’s oil sector would collapse within days under the U.S. naval blockade, saying export revenue would fall by about $175 million per day and that shut-in wells would be irreparable, cutting capacity to about 50%. The article disputes this: while the blockade is severe, the industry is not likely to “implode,” and Iran has substantial onshore and offshore lifting and storage capacity rather than an immediate fatal limit.
Before the war Iran produced about 3 million barrels per day of crude oil (about 0.477 million m³/day) plus 0.75 million barrels per day of condensate (about 0.119 million m³/day), while domestic demand was near 1.9 million bpd (about 0.302 million m³/day), leaving around 1.85 million bpd (about 0.294 million m³/day) of potential exports. Even after two weeks of blockade, crude was still being loaded at Kharg Island onto tankers already in the Persian Gulf. Kpler estimates Iran had another 12–22 days of storage, far more than initial U.S. expectations. As storage nears capacity by mid-May, output may need to drop by about half versus pre-war levels.
Historical record strongly weakens the “irreparable damage” claim. In the 2019–2020 sanctions period, Iran cut production significantly, then restarted it, and by 2025 had returned to a 46-year high. Engineers can throttle wells gradually, rotate field shutdowns, and avoid water intrusion; therefore a production pause of weeks or a few months is generally recoverable. Petroleum consultant Robin Mills, with Iran field experience, says if the blockade is eased Iran is likely able to resume output to about 70% of pre-war capacity within months, with most capacity coming back. The blockade still imposes substantial economic strain and higher long-term recovery costs, but its main purpose is leverage in negotiation rather than immediate technical destruction.
