The Mingbulak oil spill, also known as the Fergana Valley oil spill, was the worst terrestrial oil spill in the history of Asia.
The oil spill was caused by a blowout on March 2, 1992 at the Mingbulak oil field in the Fergana Valley, Uzbekistan at well #5. The crude oil released from the well burned for two months.[1] The blowout resulted in the release of 35000oilbbl to 150000oilbbl per day. In total, 2000000oilbbl were collected behind emergency dykes. The oil stopped flowing by itself. A total of 285,000 tons of oil were released, and it was the fifth largest oil spill in history.[2] The spill is considered the largest inland spill in history.[3] It cost over $55 million to clean the oil.
