==Wettability==
The wettability, or contact angle θ, is 0° for hydrocarbon/water.<ref name=ch10r5>Berg, R. R., 1975, [http://archives.datapages.com/data/bulletns/1974-76/data/pg/0059/0006/0900/0939.htm Capillary pressure in stratigraphic traps]: AAPG Bulletin, vol. 59, no. 6, p. 939–956.</ref> If the wetting phase is oil or gas rather than water, the contact angle can range from 0 to 180°. Not all rocks are water wet, and oil-wet seals may not be as rare as commonly thought.<ref name=ch10r15>Cuiec, L., 1987, [[Wettability]] and oil reservoirs, in J. Kleppe, E. W. Berg, A. T. Buller, O. Hjemeland, and O. Torsaeter, eds., North Sea Oil and Gas Reservoirs: London, Graham and Trotman, p. 193–207.</ref> Organic-rich sediments may be source, seal, and oil wet.
