Abstract
Methods for treating a subterranean formation with a treatment fluid comprise introducing the treatment fluid into a wellbore extending into a subterranean formation, measuring a surface treating pressure, changing a concentration of the friction reducer to have at least two surface treating pressure measurements within a surface treating pressure range, establishing a relationship between the surface treating pressure measurements and the concentrations of the friction reducer, evaluating a friction reducer efficiency, and selecting the friction reducer with the best efficiency for a next stage of a multistage fracturing job. The treatment fluid includes water, an acid, a corrosion inhibitor, and a friction reducer.

A method comprising:
- setting a surface treating pressure range for a first stage of a multistage fracturing job;
- introducing a treatment fluid into a wellbore extending into a subterranean formation, wherein the treatment fluid comprises:
- water;
- an acid;
- a corrosion inhibitor;
- and
- a friction reducer;
- measuring a surface treating pressure;
- changing a concentration of the friction reducer to have at least two surface treating pressure measurements within the surface treating pressure range;
