Geothermal ESP
One of the hottest topics for Artificial Lift is the application in geothermal wells as sustainable energy source.
- Hydrothermal Systems (low and high enthalpy systems) in sedimentary and fractured carbonates with existing aquifers are transferring heat energy for heating, but also commercial electricity generation is possible (>120°C).
- Petrothermal Systems (EGS - Enhanced Geothermal Systems) are generating electricity from geothermal energy in deeper cristalline formations without aquifer, using the Hot Dry Rock (HDR) process.
Of course in both applications your Artificial Lift system must withstand high temperatures, but what else is important?
How we can support you:
Usually geothermal applications need high production rates to generate economic heat output. There, special attention should be paid on motor and seal section. In order to withstand high temperatures, we are reviewing design and material selection in detail. In addition, we account for solid content, naturally occuring radioactivity, scaling tendency and corrosivity of the produced hot water. Our team is supporting you in selecting the right ESP system and reasonable operating ranges for your geothermal wells. Increasing your geothermal project economics, our focus lays on long run life and stable high rate production.
