In late August, Turkey’s president Recep Tayyip Erdogan announced that the Turkish Petroleum Corporation (TPAO)’s FATIH drilling ship discovered a 320 billion cubic meters (bcm) i.e. 11 trillion cubic feet (tcf) of natural gas reserves in the Black Sea, within the western part of Turkey’s Exclusive Economic Zone (EEZ). The reserve — identified to be within the Tuna-1 exploration zone — was discovered some 4,525 meters below the sea bottom, at near 2 km depth. News of the discovery has been welcomed in Turkey as a game-changer with regards to the country’s expensive natural gas import bill.
