Numerical modelling of the cooling effect in geothermal reservoirs induced by injection of CO₂ and cooled geothermal water

The utilization of geothermal energy can reduce CO 2 emissions into the atmosphere. The reinjection of cooled return water from a geothermal field by a closed loop system is an important strategy for maintaining the reservoir pressure and prolonging the depletion of the geothermal reservoir by avoiding problems, e.g., water level drawdown, ground subsidence, and thermal pollution. However, the drawdown of water injectivity affected by physical...
