Apparatus and method for inverting polymer latices

An inversion system comprising:

• a. a single inversion device, the inversion device comprising at least one inlet and an outlet, the device designed and adapted to provide a pressure drop of about 2 psi to 150 psi between at least one inlet and the outlet;
• b. a water-in-oil latex source fluidly connected to an inlet, the latex comprising about 10 wt % to 80 wt % of a water soluble polymer having a weight average molecular weight of about 1,000,000 to 100,000,000 g/mole;
• c. a water source fluidly connected to an inlet, the water source being a high temperature water source, a high total dissolved solids water source, or a high temperature/high total dissolved solids water source;
• and
• d. a polymer solution in fluid communication with the outlet, the polymer solution comprising about 10,000 ppm or less of the polymer and having a viscosity about 80% to 100% of an expected viscosity of the polymer solution in the absence of shear
• and characterized by a filter ratio of about 1.5 or less.
