The UK legislator with primary responsibility for energy has claimed that exhausted fracked wells will be suitable for re-use as a geothermal energy supply (not necessarily geothermal for electricity production, but rather for heat distribution, so let's say 80° - 250°C. Is there much of a co-location of the geo-thermal resource in the UK, with the more easily obtained frackable fossil fuels; and would an exhausted fracked well be structurally suitable for this?
