Oil workers arrive at the island of Chilov in the Caspian Sea
Oil workers arrive on the island of Chilov in the Caspian Sea, about 70 km (44 miles) east of Baku, January 23, 2013. Oil in Azerbaijan dates back to the 19th century and though the industry faltered when the country gained independence after the fall of the Soviet Union, investment has returned, new reserves tapped and oil started to flow again. Forty three million tonnes of oil was pumped in 2011 and contributed more than half of Azerbaijan's gross domestic product (GDP). Picture taken January 23, 2013.
