Short summary
The Iceland Deep Drilling Project research well IDDP-2 at Reykjanes, Iceland, reached supercritical conditions at 4.5 km in January 2017. The bottom hole temperature was 426 °C and the fluid pressure was 34 MPa. Reykjanes is the landward extension of the Mid-Atlantic Ridge in Iceland, and unique among Icelandic geothermal systems in being recharged by seawater. The setting and fluid characteristics at Reykjanes provide a geochemical analog of a mid-ocean ridge submarine black smoker system.
