Geothermal Well Project Support

Enhancing Well Integrity for Sustainable Energy Production

CRA provides corrosion-resistant alloy tubulars and expert technical guidance to support the unique material requirements crucial to ensuring life-of-well integrity for your geothermal project.

What Challenges Do Geothermal Projects Face?

As the world actively seeks to diversify its energy sources, sustainable geothermal energy production is set to play a pivotal role in shaping our future energy landscape. However, due to the nature of geothermal applications, these projects can face multiple challenges during the well design and construction phase. Factors such as high loads, acidic environments, and geological uncertainties can have a major impact on long-term well integrity if not properly addressed.

Furthermore, as the demand for low-enthalpy domestic heating continues to rise, there is a growing emphasis on safeguarding freshwater aquifers that are in proximity to these wellbores. Additionally, with geothermal operators targeting lower pH environments that can provide higher outputs, there is a heightening need for robust well construction.

Corrosion-Resistant Alloys For Life-of-Well Assurance

These factors are driving the utilization of corrosion-resistant alloy material and tubulars in the approach to both new well design and execution, as well as the remediation of shut-in, non-productive wells. Utilizing corrosion-resistant alloy material and tubulars results in several notable benefits:

  • Enhanced protection for aquifers
  • Reduced risk of corrosive fluid ingress 
  • Operators can confidently target Low Ph Environments
  • Safe in the knowledge they can achieve life-of-well integrity.

Frequently Asked Questions

How do geothermal wells generate power?

Open loop geothermal systems use direct sources of hot well water to create the steam that powers generators. Water or steam comes up through the pumps and is then pumped back down to its source to be reused.

Closed loop system a set volume of working fluid circulates in a closed area near a well. When hot water rises from the well, it meets a heat exchanger, which transfers the water’s heat to the working fluid. From there, the working fluid turns into steam.
