Lower-temperature water injection alters subsurface stress concentrations around deep wells, threatening wellbore stability through intense thermomechanical interactions.
Assessment using Kirsch formulas and coupled thermomechanical 2D finite element analysis reveals localized yield zones under extreme high-temperature conditions.
May enable safer thermal extraction across 20+ MW superhot rock geothermal reservoirs, but requires careful operational management during fluid injection phases.
