Sustainable and cost-efficient Concepts enabling green power production from supercritical/superhot geothermal wells
Solutions developedThe EU-funded COMPASS project will address the main technical challenges of drilling into superhot formations. Those challenges include well integrity issues due to high temperature, and corrosive fluid chemistry. COMPASS will deliver improved and innovative well design to solve those challenges. Novel foam cement solutions suitable for high-temperature formations will be developed to improve well integrity, and cost-effective laser cladding will be used to improve corrosion protection inside the casing pipes.
Main resultsDeveloping improved and innovative well casing technologies
-To mitigate casing failures, novel foam cement solutions will be developed suitable for high temperature formations. This system would work with available flexible couplings to mitigate high-temperature induced stresses and ensuring well integrity.
- Cost-effective laser-cladding will be used to improve corrosion protection inside the casing pipes.
These technology developments will be enhanced with a robust well design solution addressing challenges, reducing project risk and enabling reduction of LCOE. The new well concept will enable cost-effective geothermal developments in new types of geological settings and new regions.
