Figure 5.17 Analysis of thermal reservoir evolution for
single and double borehole stimulations, profile (a) and
thermal drawdown (b).
THM simulations, a parallelized version of the numerical code was used (Wang
et al., 2009).
In order to present and discuss the results we use different illustrations: variances,
frequencies, and envelope curves. Figure 5.18 (b) shows the average temperature
as well as the standard deviation in a horizontal cross section through the reservoir
