Abstract
A method for selecting a demulsifier for breaking a water-in-oil emulsion employs at least two electrodes to be immersed in a plurality of emulsion samples, each having a different demulsifier added. The current flow between the electrodes is recorded for each sample. The demulsifier producing the most rapid rate of change of current flow is identified as the most effective demulsifier in breaking the water-in-oil emulsion.
