The influence of oil composition and content of aqueous phase on microstructure, rheological properties, and activation energy of viscous flow of water-oil emulsions is shown. For oils with the ratio RAC/PHC < 1, the increase in water cut results in an increase in viscosity, activation energy of viscous flow, and pour point UR - http://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000656157 ER -
