DEMULSIFICATION OF WATER-IN-OIL EMULSION |
摘要 |
A method of demulsifying a water-in-pil emulsion is provided. The method includes treating a volume of fluids comprising oil and water by adding a salt of a polynuclear, aromatic sulfonic acid to the fluids so as to cause the oil and water to be at least partially demulsified. The method may further include separating water and oil in a separator. A method of producing hydrocarbons from a subsurface reservoir is also provided. The hydrocarbons include a water-in-oil emulsion. The method includes producing the hydrocarbons through a wellbore, and subjecting the water-in-oil emulsion to a salt of a polynuclear, aromatic sulfonic acid additive so as to cause the oil and water to be at least partially demulsified.
