Reducing formation damage by artificially controlling the fluid-rock chemical interaction in a double-well geothermal heat production system

Direct heat production by double wells is widely used to extract thermal energy from geothermal reservoirs. However, geothermal water is often type of brine with high dissolved salts. Injection and extraction of the geothermal fluid may cause strong chemical reactions, leading to scaling in the wellbore and reservoir. Such process was seldom considered in the heat production optimization. This study numerically investigated the mechanism of...
