ABSTRACT:
An automated method of determining relative permeability is described comprising the steps of injecting known flow rates of water and a hydrocarbon into a core; measuring a pressure differential across the core; flowing the water and the hydrocarbon into a water-hydrocarbon interface measuring column; monitoring an interface level in the column with an ultrasonic probe, and calculating relative permeability with an automated device based on the pressure differential and the interface level.
