Objectives
Develop cement and sealing technologies optimized for high-enthalpy geothermal applications in order to ensure casing protection and zonal isolation at elevated temperatures and pressures (up to 450°C and >100 bars). Assess the potential of using high temperature composite casings.
- Improve current cement curing kinetics and performance
- Reduce thermal strains and stresses in the wellbore by implementing a ductile layer between casing and cement (conduct lab tests and numerical simulations)
- Design and test of high temperature composite casing (HTCC)
- Assess the performance of (hardened) cement and interfaces at representative P/T conditions by a combined experimental/modelling approach
