[[:file:evaluating-top-and-fault-seal_fig10-50.png|Figure 1]] shows the range of seal capacities of different rock types. This figure was compiled from published displacement pressures based upon mercury capillary curves. Column heights were calculated using a 35°API oil at near-surface conditions with a density of 0.85 g/cm³, an interfacial tension of 21 dynes/cm, and a brine density of 1.05 g/cm³.
