An experimental study was carried out to examine the evolution of flow patterns in both time and space under different flow regimes, caused by incongruent dissolution of fractured dolomite. Analysis of oscillatory behavior of the overall hydraulic conductivity was based on the fluid residence time, which influences strongly aragonite and calcite precipitation in fractured dolomite rocks. The results are in accordance with field observations.
