Modeling Highly Buoyant Flows in the Castel Giorgio: Torre Alfina Deep Geothermal Reservoir

Table 1

Hydraulic and thermal parameters of the lithostratigraphic units involved in the natural state simulation. Values are taken from literature [23–25, 30, 31, 57, 61–63, 65, 70]. For the unit name the added specification, in and out are used for formations stacked into ((4b), (5b), and (6b)) or outside ((4a), (5a), and (6a)) the proper geothermal reservoir, respectively.
