Characterization of Sb scaling and fluids in saline geothermal power plants: A case study for Germencik Region (Büyük Menderes Graben, Turkey)

Geothermal gradient variation in the Büyük Menderes Graben: implications for geothermal potential of the graben, Western Anatolia, Turkey

“…As of 2019, there were 27 operating geothermal fields in Western Anatolia, and 16 of those were in the BMG (Mertoğlu et al, 2019). Tonkul et al (2021) conducted a case study of the Germencik Geothermal Field in the western BMG. They used numerical modeling to create a 3D distribution of the subsurface temperatures in the field (Figure 8).…”

“…This suggests that the IGF has a higher geothermal gradient than the GGF at a depth of 2 km. The GGF case study by Tonkul et al (2021) used 3D interpolative numerical modeling in Leapfrog to validate their reservoir temperature calculations obtained by geothermometry. In the GGF, geothermometry has shown that the reservoir temperature is between 190°C and 232°C (Tonkul et al, 2021).…”

In the GGF, geothermometry has shown that the reservoir temperature is between 190°C and 232°C (Tonkul et al, 2021). The reservoir temperatures for the GGF obtained by geothermometer calculations are consistent with those obtained by numerical modeling.…”

“…Yamanlar et al (2020) noted that the geothermal gradient is variable throughout the BMG, with the highest gradient in the eastern section and the lowest in the middle of the graben (Figure 3). Tonkul et al (2021) performed 3D reservoir temperature modeling of the Germencik Geothermal Field (GGF) in the western BMG, showing reservoir temperatures vary between 150-200°C. The reservoir temperatures for the middle of the graben have been reported to be between 169 °C-188 °C (Haklıdır and Şengün, 2020).…”
