[[: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 [[trap]]s with a geometry such that only the gas column is in contact with the seal. It also applies to [[Fault trap regime|fault traps]].
