Satellite imagery captured between May 6 and May 8, 2026, reveals a suspected oil spill west of Iran's Kharg Island [1], [3].
As a primary oil export hub for Iran, any significant leak at Kharg Island could disrupt regional energy logistics and cause severe environmental damage to the Persian Gulf. The discrepancy between satellite data and official denials raises questions about the transparency of the facility's operational status.
The imagery shows a grey-white slick on the sea west of the island's eight-kilometre coastline [1], [2]. According to some reports, the slick covers up to 45 square kilometres [3]. Other estimates suggest the volume of the leak could reach tens of thousands of barrels [4].
Iran's Oil Terminals Company has rejected the reports. Officials said inspections of the area found no evidence of leaks near Kharg Island [3]. This denial contradicts the satellite sensor data that detected the slick over a three-day period from May 6 to May 8, 2026 [1], [3].
Kharg Island serves as a critical point for the shipment of Iranian crude oil. The island's coastline spans approximately five miles [1]. Because the cause of the slick remains unconfirmed by the Iranian government, the origin of the grey-white mass continues to be a subject of international monitoring [1], [3].
“The imagery shows a grey-white slick on the sea west of the island's eight-kilometre coastline.”
The conflict between independent satellite observations and official government denials is common in high-security energy zones. If the spill is verified, the volume of tens of thousands of barrels would represent a significant environmental hazard and a potential failure in infrastructure maintenance at one of Iran's most vital economic assets.
