The co-production of water with oil in enhanced oil recovery or in thermal in-situ recovery of heavy oil and bitumen can create water-in-oil (W/O) emulsion droplets, an undesirable byproduct giving rise to problems of transport, corrosion and removal of water from the oil. W/O emulsions are not easily broken chemically, but can be coalesced using high voltage a.c. or d.c. or pulsating electric fields. This report investigates theoretically the electrostatic interaction of two charged W/O emusion droplets at arbitrary separation and under the influence of an applied uniform electric field. The potential distribution in the oil medium surrounding the two spheres is first determined in terms of bipolar coordinates, then the electrostatic interaction is obtained in two stages. The additional energy of interaction due to charges on the droplet are determined by means of a standard charging process. The distortion of a spherical W/O droplet to a spheroid on application of an electric field is also determined.
