Many methods have been used to measure wettability. This paper describes the three quantitative methods in use today: contact angle, Amott method, and the U.S. Bureau of Mines (USBM) method. The advantages and limitations of all the qualitative methods-imbibition, microscope examination, flotation, glass slide, relative permeability curves, capillary pressure curves, capillarimetric method, displacement capillary pressure, permeability/saturation relationships, and reservoir logs-are covered. Nuclear magnetic resonance (NMR) and dye adsorption, two methods for measuring fractional wettability, are also discussed. Finally, a method is proposed to determine whether a core has mixed wettability.
