An improvement in the method of transporting viscous hydrocarbons through pipes is disclosed. Briefly, the improvement comprises adding water containing an effective amount of the adipate ester of a certain polyoxyethylene-polyoxypropylene block polymers. The method is especially useful when co-produced "hard" water is used. The resulting oil-in-water emulsion has a lower viscosity and is more easily transported.
