n: displacement of hydrocarbons or fluids in a reservoir by increasing the non wetting phase saturation. See nonwetting phase.

n: displacement of hydrocarbons or fluids in a reservoir by increasing the wetting phase saturation. See wetting phase.

n: the liquid, when two liquids are present in a pore, that has only slight, if any, attraction to the sides of the pore and that is repelled by the surface of the rock. Usually, oil is the nonwetting phase and water is the wetting phase. See wetting phase.

n: the relative affinity between individual grains of rock and each fluid that is present in the spaces between the grains. If oil and water are both present, the water is usually in contact with the surface of each grain, and the rock is called water-wet. If, however, the oil contacts the surface, the rock is called oil-wet.

the measurement of the wetting phase currently on a formation. Wetting is driven by the fluid or the surfactants in the fluid in contact with the surface.

n: the liquid in a two-liquid system that is attracted to the sides of the pore. See nonwetting phase.
