Hydraulic fracturing with slickwater is a field‐proven stimulation technology used in tight reservoirs. Because of the high pumping rate associated with slickwater fracturing, drag reduction (DR) is critical in minimizing pressure drop and the success of oilfield operations. In this paper, a new type of drag reducer (SPR) was synthesized with acrylamide and 12‐allyloxydodecyl acid sodium, and its drag reduction performance was evaluated. The results showed that the new drag reducer features low molecular weight, fast‐dissolving rate and low interfacial tension. The algorithm of estimating the drag reduction rate of non‐Newtonian fluid SPR was proposed and validated. Empirical or semianalytical models for estimating the friction ratio ( σ ) or friction factor ( λ or f ) were used to simulate the turbulence behavior of the SPR drag reducer under different Reynolds numbers (Re). The modified Virk's correlation could accurately model the turbulent behavior of the SPR drag reducer. A unified calculation formula was established in this study for different pipe diameters.
