Turkish President Recep Tayyip Erdoğan said on Wednesday he will announce a new figure for the gas reserves which the country discovered in the Black Sea when he visits a drillship there at the weekend.
In August, Erdoğan unveiled the discovery of a 320 billion cubic metre (11.3 trillion cubic feet) Black Sea field and he said in a speech that he will reveal an updated reserves number on a visit to the Fatih drillship on Saturday.
Erdoğan said more good news on natural gas reserves would come from the Fatih's ongoing activities in the region.
"By going to our drillship Fatih on Saturday, we'll both personally witness the efforts on site and announce the amount of the new reserve," he said.
Amid efforts to find domestic hydrocarbon resources, the Fatih discovered the TUNA-1 well in the Sakarya Gas Field around 170 kilometers (106 miles) off Turkey's northern coast.
The discovery was the biggest in Turkey's history. Officials have said the gas from the well would be ready for public use in 2023.
