Abstract
Effects of heat, the 100% aqueous environment and a variety of drilling and cementing problems make geothermal well casing design, installation and maintenance significantly different than for oil and gas wells of similar depths. This review presents common problems that operators have experienced with tubulars that are otherwise properly designed for basic tension, burst and collapse conditions.
