Claim 0:
1. 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; and
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 selecting the secondary oil for the friction reducer comprises developing a correlation between the secondary oil and the one or more properties of the water sample, wherein the one or more properties are selected from the group consisting of: TDS; pH; temperature; ionic composition; and any combination thereof; and

adding the secondary oil to the friction reducer to form a secondary-oil-containing friction reducer.
