Deep groundwaters, esp. oil field waters, from different sedimentary basins in Germany were characterized and evaluated with respect to their damage potential in production and injection processes. Geochemical modeling with different computer programs (PHREEQE, PHRQPITZ, SOLMINEQ etc.) was used to evaluate fluid-rock-interactions as well as their damage potential during operation processes. The geochemical program PHREEQE was integrated in an expert system (XPS FROCKI) for the evaluation of operational problems (scaling, fines mobilization, reduced permeabilities) in production or injection wells.
