Image-D5.4: Strategy For Supercritical Well Design
Typical high-temperature geothermal wells reach 2000-3000 m in total depth aiming for medium to high-enthalpy geothermal fluids that reach the surface as two-phase steam or in some cases single-phase saturated steam. The Iceland Deep Drilling Project (IDDP) consortium was established in 2000 (Fridle...
