Türkiye's southeastern Diyarbakır Basin has the long-term potential to produce up to 250,000 barrels of oil per day (bpd), the chair of U.S. energy company TransAtlantic Petroleum said on Monday.

Türkiye currently consumes about 1 million barrels of oil per day, meaning the projected production from the Diyarbakır Basin could cover roughly one-quarter of national demand.

Potential daily gas production from the basin could be around 25 million cubic meters, TransAtlantic Petroleum CEO Malone Mitchell III told Anadolu Agency (AA) on the sidelines of an energy conference in Istanbul.

"Quite nice production, 25 to 50 million. That would be a substantial portion of Türkiye's internal demand," Mitchell said.

He said the full potential of the Diyarbakır Basin is difficult to quantify precisely as productivity is expected to vary across different parts of the play, but added that it could ultimately host more wells than all those currently operating across Türkiye.
