Compaction and diagenesis during burial cause a progressive reduction in pore throats in most seal lithologies. In addition, the interfacial tension of the hydrocarbons changes with depth and affects seal capacity. Most importantly, the interfacial tension of oil and gas changes at different rates.<ref name=ch10r92>Watts, N., L., 1987, Theoretical aspects of cap-rock and fault seals for single and two-phase hydrocarbon columns: Marine and Petroleum Geology, vol. 4, no. 4, p. 274–307., 10., 1016/0264-8172(87)90008-0</ref><ref name=ch10r67>Schowalter, T., T., 1979, Mechanics of secondary hydrocarbon [[migration]] and entrapment: AAPG Bulletin, vol. 63, no. 5, p. 723–760.</ref>
