The MTA General Directorate is planning for the drilling of a geothermal exploration well in the Yildizeli district of Sivas province, Türkiye.
The General Directorate of Mineral Research and Exploration (MTA) is planning geothermal exploration in the Yildizeli district of Sivas Province, Türkiye. After the exploration, the operation of the geothermal site will then be transferred with a tender.
This news comes just shortly after the recent announcement of a geothermal exploration scheme by MTA in the Adana province.
The geothermal resource exploration activity is planned by the Ministry of Energy and Natural Resources and MTA will within a 5400-square meter area of the 4999 hectares covered by the Sivas Province AR:28 License.
Within the scope of the project, one well is planned for drilling in the Gökkaya Village of the Yildizeli District of Sivas Province. The cost of the project is calculated as approximately 10 million TL (approx. USD 427,000). The Gaziköy-1 borehole to be drilled on private land is expected to be 1500 meters deep.
In case the requested geothermal fluid data is reached, the registered license on behalf of the MTA General Directorate will be transferred through tender within the scope of the relevant Laws and Regulations. All permits during the operation phase will be obtained by the legal/private persons/enterprises that take the site.
There is a report prepared by MTA on the investigation of the geothermal energy potential of the “Sicakcermik Joethermal Field” located 29 km west of Sivas Province and the possibilities to benefit from this potential.
According to this report, the geological succession in the area consists of Paleozoic-aged Karacayir Formation, Mesozoic-aged It Mountain Limestone, Cenozoic (Tertiary)-aged Hafik Formation and ?Incesu Formation, and Quaternary-aged Sicakcermik Travertine. Dip-slip normal faults and fold structures are signs of tectonic activity in the region. According to the data obtained, the Mount It Limestone is the main reservoir rock. Hafik and Incesu Formations have the characteristics of cap rock in terms of their general conditions.
All hot waters are of basic character. The waters are warming due to a deep circulation. Although the reservoir temperature of 46-196 °C was determined according to T SiO2, T Na/K, and T Na-K-Ca geothermometers, results from these geothermometers may have uncertainties due to several factors.
In the report, it has been commented that the exact status of the geothermal potential in the region may emerge after the drilling of the proposed 600(+100) m deep drillings.
