Geothermal wells, where cold water is pumped down to where it boils and the steam comes back up to drive turbines, has some serious flaws. The biggest is that once the cold water begins to boil it wants to send steam up the same pipe where it came down. This makes a nice geyser but does not get the steam to the turbine. A lot of pumping pressure and high maintenance one-way valves are needed to keep the system working. If the pressure is really high the one-way valves won't open for the input water.

Successful geothermal projects rely on fossil groundwater that already happens to be way underground, superheated, and held in place by an impermeable layer of rock. The rock layer also has to have resisted the current fracking activity.
