A crude oil leak from the grounded tanker Caroline Bezengi has created an expansive oil slick off the coast of Oman.

The spill poses a significant environmental threat because it is located near a protected nature reserve in the Dhofar Governorate. If the leak continues unabated, the local ecosystem and wildlife in the reserve could face long-term contamination.

Authorities said that the oil slick currently covers roughly 400 square kilometers [2], which is approximately 154 square miles [1]. The leak began after the vessel ran aground, though officials have not yet been able to mount the vessel activity required to stabilize the situation.

John Amos, the CEO of SkyTruth, analyzed the site and noted a lack of intervention. "There was no sign of vessel activity at the site to stabilize the Caroline Bezengi," Amos said.

The spill was reported on Aug. 5, and analysts said the slick shows no sign of stabilizing. The scale of the leak suggests a significant breach in the tanker's hull, a condition that complicates salvage and containment efforts in the region.

Oman has not provided a specific timeline for when the leak will be stopped or when the Caroline Bezengi will be towed from its current position. The continued expansion of the slick increases the risk of the crude oil reaching the shoreline of the Dhofar Governorate.

The oil slick currently covers roughly 400 square kilometers.

The lack of immediate vessel activity to stabilize the tanker suggests a gap in rapid-response capabilities or significant logistical hurdles in the Dhofar region. Because the spill is adjacent to a protected nature reserve, the incident could evolve from a maritime accident into a major ecological crisis, potentially requiring international assistance for cleanup and wildlife rehabilitation.
