Turkey has discovered a new reserve of 75 billion cubic metres of natural gas during drilling works in the Black Sea, President Recep Tayyip Erdogan said on Saturday.
"With this discovery, we will meet the natural gas needs of homes in Turkey for 3.5 years," Mr Erdogan said during an event in Istanbul.
The discovery, with an economic value of around $30 billion, was found in the Goktepe-3 well at a depth of 3,500 metres.
Turkey's daily natural gas production at its flagship Sakarya field in the Black Sea has reached around 9.5 million cubic metres, as the country ramps up its energy ambitions both at home and abroad.
Turkey, which imports more than 90 per cent of its energy needs, is pushing to cut its import bill and boost supply security by developing domestic resources and expanding international partnerships in oil and gas exploration.
