==Asymmetric dip leakage==

Afault may dip seal on one side of a fault and dip leak on the other. This asymmetric dip leakage is caused primarily by variations in the sand-shale ratio of the fault gouge. Other possible controls in some basins include asymmetric [[fracture]] density and/or preferential hydraulic fracturing in the hanging wall.<ref name=ch10r93>Weber, K., J., Mandl, G., Pilaar, W., F., Lehner, F., Precious, R., G., 1978, The role of faults in hydrocarbon [[migration]] and trapping Nigerian growth fault structures: Proceedings, Offshore Technology conference, Houston, p. 2643–2652.</ref><ref name=ch10r71>Skerlec, G., M., 1990, SEALS: A short course for risking top seal and fault seal: Franklin, Pennsylvania, SEALS International, 600 p.</ref>
