Sustainable Geothermal Well Cements for Challenging Thermo-Mechanical Conditions

Making geothermal wells sustainable reduces financial risks, attracting investments in geo-energy. An essential risk in these wells is cement's durability providing well integrity under extreme temperatures (high-enthalpy wells), large temperature variations and chemically-aggressive environments common for all geo-wells. 

Current cement solutions either have problems under these conditions or have not been validated for durable, well-applications. This project aims to reduce risks associated with compromised well integrity and use recently gained insights in the field of materials to evaluate advanced cement systems in a wide temperature range (up to super-critical) and under thermal cycling, raise their current TRL to 5-6 by optimising and validating them in the laboratory and large-scale experiments and enabling operators to select a preferred cement formulation for target conditions.
