Abstract: A real-time or near real-time, downhole fluid formulation apparatuses and/or systems and methods of making and using same include (a) a water supply assembly/subsystem, (b) an in-line sensor assembly/subsystem, (c) a downhole fluid component supply assembly/subsystem, (d) a friction-reducing component supply assembly/subsystem, (e) a downhole fluid injection assembly/subsystem, and (f) a control assembly/subsystem, wherein (1) the in-line sensor assembly/subsystem generates data concerning various aqueous base fluid properties and (2) the downhole fluid component supply assembly/subsystem supplies downhole fluid components to the aqueous base fluid based on the aqueous base fluid properties and various formation properties, and the friction-reducing component supply assembly/subsystem supplies friction-reducing components to form a downhole fluid having a reduced or minimized percent drag reduction (% DR) value.

Abstract: Mathematical equations for predicting a percent drag reduction (% DR) value for friction-reducing (FR) polymer compositions including various polymer properties and base fluid properties as the independent variables such as base fluid salinity, type of salts in the base fluid, molecular weight of the FR polymers, FR polymer concentrations, degrees of ionicity of the FR polymers, and percent sulfonation of AMPS-containing FR polymers.

Abstract: Polymer compositions and fracturing fluids derived therefrom including a mixture of cationic hydratable polymers and anionic hydratable polymers, where the polymer composition and a hydrating water composition properties are optimized to afford a similar drag reduction and hydration viscosity compared to fracturing fluids in the absence of hydratable anionic polymers at a lower cost and methods for making and using same.
