The president of Turkey on Friday announced the discovery of major natural gas reserves in the Black Sea.
"Turkey has made the biggest natural gas discovery in the Black Sea," Recep Tayyip Erdogan said at the Dolmabahce Palace in Istanbul.
The country's drill ship Fatih found some 320 billion cubic meters (11.3 trillion cubic feet) of natural gas on July 20, said Erdogan.
He added that Turkey aimed to supply the discovered gas to public use in 2023.
The news came after Erdogan announced "good news" for the country that he had promised earlier this week.
On July 20, the Fatih drill ship began drilling in the Tuna-1 field in the Black Sea.
