摘要： 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 ) 2.5 wherein 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.

摘要： The invention describes a method for decreasing the viscosity of crude oils and residuum utilizing a combination of thermal and acidic treatment. Further, the invention describes a method for making a water-in-oil emulsion, or a solids-stabilized water-in-oil emulsion with a reduced viscosity. The emulsion can be used in enhanced oil recovery methods, including using the emulsion as a drive fluid to displace hydrocarbons in a subterranean formation, and using the emulsion as a barrier fluid for diverting flow of fluids in the formation.
