Pore–fluid interaction determines the amount and rate of hydrocarbon recovery. Reservoir pore throat radius, [[buoyancy pressure]], and fluid properties are the main elements controlling pore–fluid interaction. Since direct observation of pore–fluid interaction in the reservoir is impossible at present, [[capillary pressure]] and relative [[permeability]] analysis of rocks yields the most insight into the behavior of fluids in a particular pore system. | Pore–fluid interaction determines the amount and rate of hydrocarbon recovery.
