Figure 9: Evolution of well temperatures during the exploitation process simulation at 2 selected production (CG2 and CG1A, see Figure 1) and 2 injection (CG14 and CG14C, see Figure 1) wells: (a) and (b) refer to 50 years of exploitation process and (c) and (d) to the following 10,000 years of recovering. (e) Temperature evolution at the production wells (CG2 and CG1A) over the extended simulation time of 30,000 years.
