Mapping the Iran war’s strikes on Gulf energy

x whatsapp-stroke copylink google Add Al Jazeera on Google info By Hanna Duggal Published On 30 Aug 2026 30 Aug 2026 Oil majors in the United States are profiting from the war on Iran, as soaring energy prices boost earnings but the crisis is threatening their longstanding investments in the Gulf.

ExxonMobil and Chevron posted combined second-quarter earnings of more than $26.6bn earlier this month, buoyed by higher oil prices triggered by the closure of the Strait of Hormuz which disrupted global energy flows. Since the war began on February 28, Brent crude has risen about 22 percent, from $72 to $88 a barrel.

The strategic waterway – through which one-fifth of the world’s oil and natural gas was shipped before the war – remains largely closed to commercial traffic, though Iran and Oman agreed last week on a temporary maritime route. Iran says the strait will not fully reopen until the United States fulfils its commitments under a lapsed interim peace deal, leaving longer-term security and management arrangements unresolved.

In the absence of a lasting resolution, the disruption is likely to continue supporting higher energy prices and creating windfalls for producers, despite placing energy companies’ regional assets and future projects at greater risk.

Rahul Choudhary, vice president of Upstream Research at Rystad Energy, an independent energy research company, said the conflict has already reduced the amount of oil and gas US energy firms are drawing from the Gulf region.

“Overall we expect US companies’ share of gas supplies [from the region] to fall by around 40 percent this year compared to last year [and] the share of oil supplies to drop by 30-35 percent,” he told Al Jazeera.

While higher commodity prices have helped offset the immediate financial impact, Choudhary said prolonged disruption is likely to delay major projects and weigh on the future growth plans of US oil and gas companies with a presence in the region.

The surge in the oil price since early March, when Iran first closed the Strait of Hormuz, has delivered a windfall for oil companies, but gains have been tempered by challenges in the Gulf.

Chevron has limited exposure to Arab Gulf supply disruptions, with the region accounting for just 5 percent of its total global output. The group reported its highest quarterly profit in six years of $12bn in adjusted earnings on July 31.

ExxonMobil, by contrast, has been far more exposed to disruption in the Middle East, with the closure of the Strait of Hormuz and Iranian attacks on US-linked infrastructure in the region affecting its operations in Qatar and the United Arab Emirates (UAE), which together account for 20 percent of its global equity upstream supply, according to Choudhary.

“We already saw in H1 [the first half of] 2026, the company’s upstream earnings dropped by around $1.3bn compared to H1 2025, due to lower upstream volumes from the Middle East. However, the shortfall was covered well by higher commodity prices,” Choudhary said.

The contrast highlights a broader divide between those US energy companies which have benefitted from tighter global supply – and the corresponding rise in the oil price – and those with assets, partnerships or operations in the Gulf at greater risk of disruption caused by recent attacks on energy facilities.

The Gulf’s energy sector is dominated by state-owned giants such as Saudi Aramco, Abu Dhabi National Oil Company (ADNOC) and QatarEnergy.

Although these national oil and gas companies retain control over the region’s reserves and core infrastructure, US energy firms have carved out strategic positions across the region.

US companies generate revenue through stakes in production assets, joint ventures, production agreements, refining and petrochemical projects, as well as through long-term contracts to provide equipment, engineering and operational expertise.

ExxonMobil has some of the largest US commercial interests in the Gulf.

The company has been a major partner in Qatar’s LNG sector for decades, holding stakes in several QatarEnergy LNG joint ventures linked to the expansion of the North Field. The field is the Qatari section of the North Field-South Pars structure, the world’s largest natural gas field, which Qatar shares with Iran, where it is known as South Pars. ExxonMobil also holds an interest in the UAE’s Upper Zakum offshore oilfield alongside ADNOC.

Similarly, ConocoPhillips joined the North Field East (NFE) and North Field South (NFS) expansion projects with QatarEnergy in 2022 to increase export capacity at Ras Laffan.

The US group, Occidental Petroleum, has become one of the largest foreign producers in Oman, operating the Mukhaizna heavy oilfield, the country’s biggest producing oilfield. It also holds interests in UAE gas and pipeline projects.

Chevron maintains a smaller but strategically important Gulf footprint. Through Saudi Arabian Chevron, the company operates oil assets in the Saudi-Kuwait Partitioned Zone, including the Wafra field. In July, it said it was exploring potential routes to move Iraqi crude to Mediterranean export terminals, which could reduce reliance on the Strait of Hormuz.

According to the Armed Conflict Location and Event Data (ACLED), a US-registered independent conflict monitor, Iran and Iran-backed groups in the region have carried out at least 172 attacks on nonmilitary infrastructure across the six Gulf Cooperation Council (GCC) countries since the US and Israel launched their war on February 28.

Energy infrastructure has been hit hardest, with oil and gas facilities, along with power plants and desalination plants, accounting for nearly half (48 percent) of all strikes on nonmilitary targets.

The UAE, Kuwait and Bahrain have suffered the highest number of successful strikes, with the majority aimed at oil and gas facilities.

Among the sites that have been struck are Kuwait’s Mina Abdullah and Mina al-Ahmadi refineries, the Bahrain Petroleum Company oil ref...
