Abstract
The authors regret that during a post-publication review of the numerical model, we identified that rock thermal conductivity and rock heat capacity were not transferred properly for the ensemble run and were set to zero for the energy conservation equation. This resulted in earlier thermal breakthroughs because conductive heat transfer between the reservoir and the surrounding rock matrix was not accounted for. After correcting the model and rerunning the simulations, we found that the correction affects only the reported numerical values. The overall trends, relative comparisons between scenarios, interpretations, and scientific conclusions presented in the paper remain unchanged. The inclusion of rock thermal conductivity primarily delays thermal breakthrough and therefore we extend the simulation time from 30 years to 80 years in base case to capture long-term thermal behavior. The sensitivity analysis indicates that the ranking of parameter importance remains consistent, whereas the magnitude of the importance scores increase after introducing the rock thermal conductivity and rock heat capacity.
