Abstract
A method of determining properties of a fluid having an oil phase, a water phase, and an emulsion phase between the oil phase and water phase includes emitting an electromagnetic wave into the fluid, measuring an amplitude of a reflection of the electromagnetic wave off an interface between the oil phase in order to determine a height of a coalescing portion of the oil/emulsion interface. A height of a creaming portion of the emulsion/water interface is then determined using the coalescing portion height, total fluid height and water-in-liquid ratio. A thickness of the emulsion phase is determined based on the difference between coalescing and creaming portion height.
