I live nearby Bagneux, one of the cities mentioned in the article. People who are living near the drilling location are complaining a lot due to the noise and vibrations. It seems the drilling has to be performed continuously (24/7) so it's impossible to sleep or even live quietly. The company is paying hotel nights for many inhabitants.
Did they say how long the drilling operation should last?
4 months to go 1800m deep. It's now finished.
Total cost of the project is 34M€ (11M€ just for the drilling).
