Chapter Eight

Hydraulic Fracturing Chemical Selection and Design


This chapter begins with the introduction of different chemicals added to hydraulic fracturing fluid, such as friction reducer (FR), FR breaker, biocide, iron control, and scale inhibitors. The application of linear gel, gel breaker, buffers, cross-linker, and surfactant is also explained. The importance and application of each added component is detailed. Experimental techniques required for chemical selection and optimization, such as a flow loop test is presented. This chapter also provides examples to calculate the friction pressure.
