Dynamic reduced order modelling (ROM) of chemical and mechanical processes in CO2-cement systems

Damaged wells pose a significant risk of leakage of reservoir fluids stored in a geological CO2 storage site. The leaking CO2 can react with well cement and alter its chemical, mechanical, and hydraulic properties. Recently, we have developed an experimentally-calibrated model that couples two-phase flow, reactive transport of brine, cement geochemistry, and geomechanics to predict the leakage of reservoir fluids through a fractured pathway in a cemented well (Iyer, et al. 2018, Iyer, et al. 2017, Walsh, et al. 2013, Walsh, et al. 2014, Walsh, et al. 2014)
