Hot Fractured Rock: HFR system
Stacked Enhanced Geothermal System
Note the 270 degree heat at 4.5km in the image above
Below is the Heat Exchanger Within Insulator (HEWI) Model by Petratherm
This model avoids the difficulties associated with drilling into very hard granites at great depths.

This type of system is regarded as a "conventional" Geothermal System
Kuth Energy"s NFHR
NFHR is a new concept, unique to KUTh Energy, in which geothermal development targets hot natural fluids hosted by deep, permeable fracture systems (Figure 1). NFHR unites the strengths of
existing play concepts such as Hot Dry Rock (HDR) and Hot Sedimentary Aquifer (HSA) through a combination of in situ permeability, potential for high fluid flow rates and likelihood of high
temperatures derived from a local high-heat-producing granitic source.
