ABSTRACT:
Method to determine the viscosity of a water-in-oil emulsion that will be formed by an oil comprising organic acids when mixed with water comprising:determining the value of the expression:η(emul)=K⁢⁢η(oil)⁢TAN-r(1-ϕ)2.5wherein η(oil)is the viscosity the oil, TAN is the total acid number of the oil, φ is a number in the range of 0.1 to 0.8, r is a number in the range of about 0.5 to 2, and K is a number from about 1 to 20, said determined value, η(emul)being the viscosity of the water-in-oil emulsion.The method is used to prepare water-in-oil emulsions of predetermined viscosity and to improve desalting of oils.
