Abstract:
The present disclosure relates to fracturing fluids that use friction reducers. The composition of the present disclosure is a slurry comprising a water-soluble polymer suspended in an oil-based vehicle with the aid of a suspension agent and a surfactant. Specifically, the water-soluble polymer is polyacrylamide and the oil-based vehicle is petroleum distillate. The surfactant is an ethoxylated nonionic emulsifier. The surfactant can be a fatty chain EO/PO (ethylene oxide propylene oxide) and/or oxylated propoxy copolymer. The suspension aid is any variation of diblock copolymers based on styrene and ethylene/propylene. The composition may also contain a dispersant such as organophilic clay or a synthetic alternative as the suspension agent.
