Geothermal prospects in Turkey are heating up

Geothermal exploration activities are scheduled to commence in the Adana and Sivas provinces of Turkey.

The General Directorate of Mineral Research and Exploration (MTA) has obtained the AR:18 License for an extensive area covering 4,983.5 hectares in the Adana province. As part of this license, the MTA intends to drill a well in the Kuzgun Village of Karaisali District, with an estimated project cost of approximately 10 million TL (equivalent to around USD 503,000). The planned borehole will reach a depth of 2,000 meters.

In addition, the MTA has also planned geothermal exploration in the Yildizeli district of Sivas Province, which encompasses an area of 5,400 square meters within the larger 4,999-hectare territory covered by the AR:28 License. The drilling of proposed boreholes, expected to be 600 (+100) meters deep, will provide valuable information about the geothermal potential in the region.

A geological report from earlier exploration highlights the composition of the Sivas region, which comprises several formations, such as Paleozoic-aged Karacayir Formation, the Mesozoic-aged It Mountain Limestone, the Cenozoic Hafik Formation, and Incesu Formation. Tectonic activity in the area is evident from the presence of dip-slip normal faults and fold structures. The primary reservoir rock identified is the Mount It Limestone, while the Hafik and Incesu Formations possess characteristics suitable for cap rock formations.

Turkey is a country known for its active geological activity, which makes it a promising prospect for establishing traditional geothermal plants. Additionally, Eavor’s Advanced Geothermal Systems (AGS) have the potential to unlock even greater geothermal energy resources in the country. The versatility and sustainability of this closed-loop system could enhance Turkey’s renewable energy portfolio while harnessing the country’s geothermal potential to meet growing energy demands.
