The oil slick near the marine border of Iran and Qatar off the coast of Asalouyeh in Bushehr Province has been removed. Speaking to Mehr News Agency, Tiran Jasemzadeh, director of the Asalouyeh Port and Maritime Organization, said his office’s timely response “prevented the spread of the oil slick” across the Persian Gulf. Satellite images provided by the Kuwait-based Regional Organization for the Protection of Marine Environment alerted the PMO officials who “swiftly dispatched tugboats to the South Pars Oil Platform to assess the damage and resolve the issue,” he said. The 16-kilometer oil slick took two days to clean up. It was not clear what caused the spill, but reports suggest that the slick was caused by leakage from ships. The South Pars field is a natural gas condensate field located in the Persian Gulf. It is the world’s largest gas field, shared between Iran and Qatar.
