  • Patent number: 9725660
    Abstract: In one implementation, a method for recovery of crude oil from a production fluid comprising an oil-water emulsion is provided. The method comprises adding a solid hydrophilic compound to the production fluid to form a production fluid-solid hydrophilic compound mixture. The method further comprises separating the production fluid-solid hydrophilic compound mixture to produce an oil phase containing the heavy crude oil and a water phase containing the solid hydrophilic compound. The production fluid-solid hydrophilic compound mixture may be separated by centrifuging the production fluid-solid hydrophilic compound mixture to produce the oil phase and the water phase. After separation, the oil phase may be analyzed to determine at least one of: oil composition, physical properties, and geochemical analysis. The crude oil comprises at least one of heavy crude oil, bitumen or combinations thereof.
