Short summary
The Iceland Deep Drilling Project (IDDP) aims to investigate utilization of supercritical fluids. These fluids are considered to provide 10x more energy compared to conventional geothermal wells. During the IDDP-2 well stimulation, casing at about 2300 m depth was damaged and therefore the discharging fluid comes mainly from this depth instead of depths at higher temperature. The chemical composition of the discharge is, however, indicating minor contribution from the deeper depths.
