Fig. 2

Intrinsic permeability of the rock samples before and after the experimental runs. On the y axis the intrinsic permeability (mD) is shown. The x axis displays the used samples (identified by their number/name). White bars with few dots illustrate the permeability of the unpercolated rock samples whereas the strongly dotted bars show the permeability of the percolated rock samples after the experiment
