HP configuration for different inlet size. (a–l) Temperature (∆T) and pressure (∆P) changes and gas saturation (\({S}_{\mathrm{g}}\)) during the unrest phase; (m–u) radial distributions of horizontal (U) and vertical (V) displacements and of gravity changes (\(\Delta g\)) on the ground surface over time (from 0.0 to 1.0 year) induced by the injection of 1485 t/d of H₂O and 726 t/d of CO₂, at a temperature of 600 °C. The unrest phase was simulated for the HP configuration for three different sizes of inlet: 40 m (left panels), 100 m (central panels), and 200 m (right panels)
