==Fault control of pressure gradients==

Faults control changing pressure gradients within a field. Hydrocarbons move in response to these pressure gradients and not necessarily in response to structural dip. Gas in the Beryl field, for example, migrated downdip during production in response to changing pressure gradients, [[pressure compartments]], and [[[[migration]] pathways]] controlled by sealing and leaking faults.<ref name=ch10r43>Knutson, C., A., Erga, R., 1991, Effect of horizontal and vertical permeability restrictions in the Beryl reservoir: Journal of Petroleum Technology, vol. 43, p. 1502–1509., 10., 2118/19299-PA</ref><ref name=ch10r74>Skerlec, G., M., 1997b, Atlas of fault seal behavior in the Gulf Coast: Franklin, Pennsylvania, SEALS International, 4356 p.</ref>
