AC field induced destabilization of water-in-oil emulsions based on North Sea acidic crude oil

•Viscosity drop and separation of water-in-crude oil emulsions.•Droplet collision frequency enhanced by the shear movement.•Combined effect of flow regime and voltage.•High frequencies do not initiate drop deformation and breakage. The current work explores the effects of alternating current (AC) el...
