Abstract
A cross-linked phenolic resin demulsifier may be added to a water-in-oil emulsion having at least one foulant therein. The demulsifier may separate at least a portion of the foulant(s) from the water-in-oil emulsion, and the separated foulant(s) may be removed from the water-in-oil emulsion. In a non-limiting embodiment, the amount of the demulsifier present in the water-in-oil emulsion may range from about 0.1 ppm to about 50,000 ppm.
