Oil and gas deposits were discovered near Chilov island by Russian Rear Admiral Count
Mark Voynovich while he led an expedition to the Caspian Sea in 1781. In 1944, a geological expedition was established at the Azerbaijan Academy of Sciences. This expedition began geological explorations on Chilov Island. The first oil well there was drilled by Agagurban Aliyev. In the 1950s, an air defense military unit of the USSR was stationed on the island, organizing air defense of Baku from the eastern part. For this purpose, the C75 anti-aircraft missile system was deployed on the island. In 1992-1993, all Russian troops were withdrawn from the island. ==See also==
