Geothermal doublet drilling underway in Alfortville
In France, drilling has started for a new geothermal doublet in the Alfortville commune in Paris
The new geothermal doublet will replace the existing one that has been functioning since 1986. The drilling will connect with waters at over 70°C in the Dogger formation at a depth of 1600m.
Paris, and its environs has made use of geothermal energy for over 60 years and roughly a million people in the country benefit.
The wells are planned to be in use by September this year.
