ISTANBUL, Nov. 5 (Xinhua) -- Turkey's Fatih deepwater drillship started its mission on Thursday in a new borehole in the Black Sea, Turkish Energy and Natural Resources Minister Fatih Donmez announced.
"After completing preparatory works, we started drilling in the Turkali-1 well," Donmez tweeted, noting Fatih's mission would last 75 days.
Turkali-1 is located in Sakarya Gas Field, where Turkey recently discovered 405 billion cubic meters of natural gas reserves.
The Fatih vessel had started its first drilling activities in late July in an exploration zone known as Tuna-1 in the same gas field off the northern Zonguldak province.
Turkey has been considering sending a second drillship called Kanuni, which is currently anchored at the Haydarpasa port in Istanbul, to the Black Sea for a new mission in the upcoming period.
