USBM wettability index
text:
The U.S. Bureau of Mines (USBM), developed by Donaldson et al. in 1969, is a method to measure wettability of petroleum reservoir rocks. In this method, the areas under the forced displacement Capillary pressure curves of oil and water drive processes are denoted as A 1 and A 2 to calculate the USBM index. USBM index is positive for water-wet rocks, and negative for oil-wet systems.
