Patent abstract
A process for the separation of production fluids is provided. The production fluids comprise an oil/water emulsion stabilized with fine solids. The emulsion may further comprise asphaltenes and naphthenic acids and resins. The process includes subjecting the emulsion to a flocculating agent to flocculate solids within the emulsion, and separating water and solids from crude oil in a first separator. The process further includes subjecting the separated crude oil to a demulsifier after subjecting the emulsion to a flocculating agent, and further separating water from the crude oil in a second separator. A process for producing fluids from a hydrocarbon-bearing reservoir is also provided, using the separation processes herein.
