Figure 3: Temperature vertical profiles along 3 exploration wells according to Cataldi and Rendina [23], Buonasorte et al. [24, 31]. Locations of the selected wells are reported in Figure 1. The inversion of the Alfina015 well temperature profile and the values detected at the top and at the bottom of the reservoir (140°C at −1,050 meters b.g.l. −207°C at −4,000 meters b.g.l.) prove the highly convective behavior of the system.
