The failure of intact membrane seals after charging is rare because the capillary displacement pressure of mudrock seals increases with compaction and burial. Intact seal failure usually results in failure to trap in the first place. Limitations on the height of the petroleum column due to intact membrane seal failure can be evaluated by laboratory capillary pressure tests<ref name=ch11r4>Berg, R., R., 1975, [[Capillary pressure]]s in stratigraphic traps: AAPG Bulletin, vol. 59, p. 939–956.</ref> in conjunction with estimates of in situ petroleum density.
