* Structural growth might have allowed [[Migration|migrating]] petroleum to escape to the surface. Once lost, the petroleum is no longer available to fill accumulations to economic size, so overall migration efficiency may decline.

* Areas of structural growth after charging can leak if the seal is fractured during deformation (see [[Leakage]]).
