Geothermal well construction

Geothermal well construction

Welltec® brings more than 30 years of subsurface engineering experience to the geothermal sector, providing operators with a range of reliable solutions to enhance geothermal well construction and integrity. 

Products such as the all-metal Welltec® Magma Packer (WMP) are specifically designed and qualified to withstand the hostile conditions associated with geothermal environments, offering robust resistance to acidic corrosion and extreme pressure and temperature fluctuations throughout the life of the well. In addition to geothermal well construction, our metal expandable packers can and have been utilized as relining solutions, extending the life of existing assets. 

Welltec ensures long-term safety and reliability, reduced maintenance requirements, and extended asset life with lower CAPEX/OPEX and operational complexity.

Applications

• Zonal isolation during geothermal well construction
• Stage cementing alternatives in high-enthalpy environments
• Integrity restoration through relining of existing geothermal wells
• Pressure containment across unstable or fractured formations

Benefits

• Long-term sealing performance under extreme geothermal conditions
• Resistance to acidic fluids and pressure/temperature cycling
• Reduced need for rework or intervention over the life of the well
• Reduced complexity and cost
• Suitable for both new construction and well remediation
