Stabilization of polyacrylamide emulsion formulations
Abstract:
The current invention provides a method to form a stable blend of polyacrylamide water-in-oil emulsion and breaker surfactants such as silicon polyether copolymer and linear or branched alcohol ethoxylate surfactants. The composition can be employed, for example, as a friction reducing additive for water based fracturing fluid, or a drilling mud additive.
