Türkiye Petrolleri Anonim Ortaklığı (TPAO) discovered a large gas field in the Western Black Sea. It is the first gas discovery in Turkish ultra-deep water.
Tuna-1 was drilled with 6th generation drillship Fatih in block AR/TPO/KD/C26-C27-D26-D27. The well is in 2,115 m of water and reached final total depth of 4,525 m. It encountered more than 100 m of natural gas bearing reservoir in Pliocene and Miocene sands.
Based on data collection and geophysical studies, the prospect has potentially 11 trillion cu ft of gas (about 2 billion bbl recoverable oil equivalent) which represents the largest discovery in the Turkish exclusive economic zone and the entire Black Sea.
TPAO has 100% equity in the block.
