A and B Thermal exchange maps after 1 year of geothermal extraction, for an injection well in left sector (down-facing triangle) to an extraction well in the right sector (up-facing triangle). Case 0, on the left depicts the dipole model that considers a constant-aperture fracture. Case 1, on the right, depicts the geothermal extraction that occurs for the up-scaled permeability distribution at Altona (Fig. 3C) Thermal drawdown curves over a 10 year period. Both simulations consider the following parameters: mass flow rate of 2020 \(kg\cdot {s}^{-1}\) , reservoir temperature of 200 °C, reinjection temperature of 50 °C, and an inter-well spacing of 500 m from West to East
