Drainage is the process by which a non-wetting fluid displaces a wetting fluid from a porous medium. This phenomenon is ubiquitous, and arises in diverse settings including groundwater contamination, oil migration, gas venting from sediments, CO2 sequestration, mercury porosimetry, soil drying, liquid infusion into porous membranes, and oxygen accumulation...
