A process for the preparation of low-viscosity improved stable crude oil transport emulsions. The process comprises producing a hydrocarbon crude, and mixing the produced hydrocarbon crude with an emulsifying composition(s) which contains water and is capable of assisting the formation of an oil-in-water...http://www.google.es/patents/US5000872?utm_source=gb-gplus-sharePatente US5000872 - Surfactant requirements for the low-shear formation of water continuous emulsions from heavy crude oil
