Thermal effects significantly impact stress distributions in geothermal wells, highlighting integrity concerns.
Borehole cooling in injection wells reduces radial cracking but may lead to casing collapse.
Borehole heating in production wells increases the risk of burst failures and fractures.
Closed-form expressions for thermoelastic stresses aid in understanding complex stress-deformation behaviors.
