A solubility equilibrium program GEOPROF was applied to the determination of the bubble-point depth, pressure and temperature, as well as the partial pressure profiles of the gases CO 2 , CH 4 and N 2 between the bubble-point depth and the wellhead, in two high enthalpy geothermal wells, NSZ-2 and FAB-4 in southern Hungary. The pH, alkalinity, total carbonates, and equilibrium solubility for CaCO 3 , CaSO 4 , BaSO 4 , and SrSO 4 along the well depth profile in the Na-K-Mg-Ca-H-Ba-Sr-Cl-Br-SO 4 -OH-HCO 3 -CO 3 -CO 2 -H 2 O system were also determined and the concentrations of Ca 2+ , Ba 2+ , Sr 2+ , H + , OH À , HCO 3 À , CO 3 2À , and H 2 CO 3 * were computed at the actual temperature and CO 2 pressure using the Davies and Pitzer activity calculation methods. The calculated amounts of CaCO 3 scaling along the wells and at the surface were used in estimating service life. The results for well FAB-4 contain high uncertainties because of the estimated gas separation analysis data.
