A while back we wrote a letter from the worlds hottest geothermal well. Back then we were close to measuring supercritical conditions (temperature above 374 °C and pressure above 220 bar) with our logging tool.
On the 28th of November we went back to the well for another attempt. This time it went very well, and on Friday, 1st of December, the PT (pressure and temperature) logging instrument SINTEF has designed in the H2020 project DESCRAMBLE measured a temperature of 443.6 °C in the well.
This is a new world record for electronic logging tools for geothermal wells.
The well is drilled by ENEL Green Power in the DESCRAMBLE project. The depth this temperature was measured at was 2810 m and the well has a total depth of 2900 m.
The project has now reached the goal of demonstrating drilling of a supercritical well and will end in December. In March 2018 the project will have a final conference in Pisa
