Klaipeda Geothermal Pilot Plant, operating since 2000, suffers from permanent decrease of injectivity of spent geothermal water. Among plenty and various causes of injectivity failures the most important ones are associated with scaling problem, because geothermal water is supersaturated by many minerals, salts and ions. A geochemical model PHREEQC has been used for scaling problems simulation, two other models (flow&transport) predicted scale of spread of injected geothermal water in the pumped aquifer.
