Figure 1: (a) Geographical setting of the CG-TA geothermal field (red dashed line). The geothermal producing reservoir (red shaded area), the cross-section traces A-B, and the existing geothermal wells drilled in the area are shown (where in the labels, A stands for Alfina, G for Gradoli, GC for Grotte di Castro, B for Bolsena, and Ba for Bagnoregio). (b) Enlargement of the SE area of the reservoir with location of the 5 production wells (CG1, CG1A, CG2, CG3, and CG3A) and the 4 injection wells (CG14, CG14A, CG14B, and CG14C) used in the simulation of the 5 MW field exploitation.
