A stable, low viscosity bimodal oil in water emulsion having an emulsifier, a continuous water phase and a discontinuous oil phase having an oil:water ratio of from about 70:30 to about 85:15 by weight, the discontinuous oil phase being characterized by two distinct oil droplet sizes DL and DS wherein DL is about 10 to 40 microns and DS is less than or equal to 5 microns, the ratio of DL/DS is greater than or equal to 4 and about 45 to 85% by weight of the oil is in oil droplet size DL.
The method of preparing a stable, low viscosity bimodal oil in water emulsion whose viscosity does not age with time wherein the emulsion has an oil:water ratio of from about 70:30 to about 85:15 by weight wherein the discontinuous phase is characterized by viscous hydrocarbon having a viscosity over 5000 cps at 30°C. and/sec-1 comprising: (a) providing a feedstock of water free viscous hydrocarbon with a salt content less than or equal to 40 ppm; (b) preparing separately two oil in water emulsions wherein a first oil in water emulsion has a dispersed ph...
