1. A method comprising:
combining at least a secondary-oil-containing-friction reducer and water to form a treatment fluid, wherein the secondary-oil-containing friction reducer comprises:
a continuous phase comprising a base oil and a secondary oil, wherein the secondary oil is different than the base oil and wherein the secondary oil is selected based at least partially on one or more properties of a water sample, wherein selecting the secondary oil 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;
a discontinuous phase dispersed in the continuous phase, wherein the discontinuous phase comprises water and a water-soluble polymer; and
an emulsifying surfactant; and
introducing the treatment fluid into a wellbore.
