Claim 18:
19. A method comprising:
providing a friction reducer comprising:
a continuous phase comprising a base oil;
a discontinuous phase dispersed in the continuous phase, wherein the discontinuous phase comprises water and a water-soluble polymer;
an emulsifying surfactant;

selecting a secondary oil for the friction reducer based at least partially on one or more properties of a water sample, wherein the secondary oil is different than the base oil, wherein the selecting comprises determining a total dissolved solids of the water sample, wherein the selecting comprises applying the total dissolved solids to a correlation between secondary oil Kb value and water TDS; and
adding the secondary oil to the friction reducer to form a secondary-oil-containing friction reducer.
