1. OFFICE WORK
As part of the office work, existing geological, geophysical, and geochemical studies in the regions are reviewed, and satellite images of the area are obtained and processed to determine tectonic lineaments and alteration zones.

2. FIELDWORK
At this stage, field studies are conducted to verify and enrich the information gathered during the office work, and as a result of these studies, more detailed data about the potential of the areas are obtained. The details of these studies are given below.

2-1. GEOLOGICAL REVISION
The process includes field observation and verification of the obtained geological information, as well as enriching it with new findings.

2-2. GEOCHEMICAL STUDIES
In the field, soil gas (CO2) measurements are carried out at points determined by grid-like spacing at specific intervals. Gases released from fracture zones located deep underground and containing geothermal potential reach the surface by penetrating the cap rocks due to their low viscosity. High gas values ​​obtained from gas measurements in the surface soil are used as helpful information in determining the presence and location of geothermal fluids underground.

2-3. GEOPHYSICAL STUDIES
Electrical resistivity, magnetic field, and seismic reflectance measurements are conducted in areas with geothermal potential, which have been narrowed down through both geological findings and geochemical studies. Zones containing hot water underground exhibit lower resistivity values ​​compared to surrounding rocks, both because the water is highly mineralized and conductive, and because the hot water alters and clays the surrounding rocks, making them conductive. Two different methods are used to collect data in electrical resistivity studies. In the first method, vertical electrical sounding (VES) with a Schlumberger electrode array is used to measure underground electrical conductivity properties at points up to a depth of 1500 meters. In the second method, two-dimensional and three-dimensional tomography of the subsurface is created along the defined profiles using modern multi-channel recorders and advanced data processing and interpretation programs.

In magnetic measurements, mineralization changes caused by alterations in fault zones lead to magnetic anomalies and provide supporting information in fault research.

Seismic reflection studies provide the clearest picture of the subsurface, but they are expensive and slow to implement. Therefore, after all other studies are completed, seismic reflection profiles are recorded with as few profiles as possible to more clearly see the tectonic structures observed in other studies and to obtain the final result.
