The USBM (United States Bureau of Mines) wettability index is a measure used to characterize the wettability of porous media, particularly in the context of petroleum production and reservoir engineering. Wettability refers to the affinity of a solid surface (such as rock) to preferentially attract one fluid over another, such as oil or water.
