==Finite seal capacity of faults==
==Finite seal capacity of faults==
Sealing faults may have some finite seal capacity. A fault may be able to support the pressure exerted by a 50-m hydrocarbon column but leak if the column increases to [[length::51 m]].<ref name=ch10r13>Chong, K., P., Hoyt, P., M., Smith, J., W., Paulsen, B., Y., 1980, Effects of strain rate on oil shale fracturing: International Journal of Rock Mechanics, vol. 17, no. 1, p. 35–43., 10., 1016/0148-9062(80)90004-2</ref> Recent work suggests there may be a maximum seal capacity related to the percentage of shale in the fault gouge.<ref name=ch10r97>Yielding, G., Freeman, B., Needham, D., T., 1997, Quantitative fault seal prediction: AAPG Bulletin, vol. 81, no. 6, p. 897–917.</ref><ref name=ch10r74>Skerlec, G., M., 1997b, Atlas of fault seal behavior in the Gulf Coast: Franklin, Pennsylvania, SEALS International, 4356 p.</ref> In most cases, however, the percent fill is significantly less and is limited by fault-dependent leak points rather than the seal capacity of the gouge.
