Fig. 11

Measured (green) and simulated temperature breakthrough curves for varied volumetric heat capacity c·ρ, shown for different depths and distances to the injection well. Measured temperatures are obtained from the same wells as in Fig. 3, temperature as well as time axis are rescaled for the right-hand side column. The black line indicates the base case, the blue lines indicate the scenarios with decreased c·ρ and the orange/red lines indicate the scenarios with increased c·ρ. The maximum and minimum scenarios, as derived from the literature, are displayed as the solid red and solid blue line, respectively, while the remaining sensitivity scenarios are displayed as dashed or dash-dotted lines
