A composition for an environmentally friendly hydrofracturing friction reducer product can be synthesized. A method for synthesis of a friction reducer emulsion can include using gas-to-liquid synthesized oil as a continuous phase in invert emulsion polymerization. The composition can be optimized by using a suitable amount of salt tolerant monomer for the best performance with salt tolerant features. Various inverting agents can be utilized for the self-inverting in brine with good product stability. The optimized friction reducer can be used in weighted brine hydrofracturing.
