Table 3 Values of the radius (in m), the volume (in m3) and the mass (in kT) of the cylinder for a geothermal fluid of 80 °C (sub-case 1) and 160 °C (sub-case 2)

From: New results on the gravity monitoring (2014–2017) of Soultz-sous-Forêts and Rittershoffen geothermal sites (France)

 

Sub-case 1: fluid keeps its initial temperature of 80 °C

Sub-case 2: fluid warms up until the produced temperature of 160 °C
