A geothermal well with communicating vessels, formed of an internal piping transferring an inflow down to a level of the depth of the well, and an external piping coaxial to the internal piping and with a diameter that permits ascent of the fluid upward from the distal end of the well, wherein a flange on the internal piping engages a collar connected to the external piping via spacers, wherein detection sensors generate information on oscillations of the pipings, wherein an automatic safety valve avoids overpressures, and a driven regulation valve generates information on fluid pressure, and wherein software monitors fluid circulation within the well and operates the inlet pump and the regulation valve to dampen the oscillations and prevent microseisms.
