Stretching along the Gediz Graben, Manisa’s Alaşehir, Salihli and Sarıgöl fields have been among the fastest-growing regions for geothermal power investment in Türkiye in recent years.
Typical problems in the region
In the high-temperature fields of the Gediz Graben, calcite scaling in production wells, CO₂ corrosion of surface equipment and silica risk in binary heat exchangers and reinjection lines are the main issues. Fluid properties of newly drilled wells can change in the first months, so the chemical programme needs regular review.
- Calcite scale in high-temperature wells
- CO₂ and H₂S corrosion
- Silica in binary heat exchangers
- Falling reinjection injectivity
Biyopol’s approach
Close monitoring and dose optimisation during commissioning of new wells; downhole scale inhibitor, silica and corrosion programmes for operating plants. The BiyoGeo series was developed with high-temperature stability as a key target.
Proximity advantage
The Alaşehir and Salihli fields are about two hours by road from our plant in Menderes; site visits and sampling can be planned within the same day.
| Stage | Main need | Priority programme |
|---|---|---|
| New well commissioning | Rapidly changing fluid | Close monitoring, dose optimisation |
| Operating flash/binary plant | Calcite, corrosion, silica | Downhole scale inhibitor + silica/corrosion |
| Reinjection | Loss of injectivity | Silica inhibitor + oxygen control |
Frequently asked questions
When should we start a programme for a new well?
Ideally before production starts, designed from fluid analyses taken during well testing.
How is product stability at high temperature verified?
With a laboratory temperature-stability test followed by a controlled field trial.
Is a single supply possible for several plants?
Yes; regular deliveries to several fields and a joint monitoring report can be arranged.
