[[:file:evaluating-top-and-fault-seal_fig10-52.png|Figure 1]] compares the seal capacity of a top seal with a single-phase oil accumulation, a single-phase gas accumulation, and a two-phase accumulation with both an oil leg and a gas cap. The largest hydrocarbon column is sealed by the two-phase accumulation. This best applies to traps with a geometry such that only the gas column is in contact with the seal. It also applies to fault traps.
