Deep faults channel geothermal energy to the shallow ground, Received in revised form 27 December 2016 which makes it difficult to study due to the hidden nature. We conducted numerical experiments in order Accepted 27 December 2016 to investigate the physical states of the geothermal water inside the fault zone. We view the deep fault as Available online 29 December 2016 a fast flow path for the thermal water from the deep crust driven up by the buoyancy. Temperature mea- surements at the springs or wells constrain the upper boundary, and the temperature inferred from the Keywords: Currie temperature interface bounds the bottom. The deepened boundary allows the thermal reservoir to Solid tide revolve rather than to be at a fixed temperature. The results detail the concept of a thermal reservoir in Geothermal Reservoir terms of its formation and heat distribution.
