Abstract
The present invention generally relates to methods for resolving water and oil emulsions in the produced fluid of an oil production system comprising adding a structured copolymer reverse emulsion breaker to the produced fluid of the crude oil production system in an amount effective for resolving an oil-in-water emulsion. In particular, these methods for resolving an oil-in-water emulsion can be used in separation processes where the oil and solids in the produced fluid are separated from the produced water in the produced fluid.
