Effect of polyacrylamide friction reducer on calcite

A friction reducer (FR) is one of the common chemicals used in Marcellus hydraulic fracturing operations. The friction reducer is necessary to reduce the frictional effects (extra pressure) that occur as water is pumped down the long pipe (wellbore) during the hydraulic fracture treatment.

High Concentration Polyacrylamide-Based Friction Reducer Used

Friction reducers from PfP Industries are intended to help make the hydraulic fracturing fluid slicker. This process is sometimes named “slickwater” for the entire process. Polyacrylamide, a water-soluble polymer, is added to the friction suspension to help reduce friction and boosts the viscosity of the hydraulic fluid.

Effect of polyacrylamide friction reducer on calcite

The goal is to hydraulically fracture the underground rock where the oil and natural gas are trapped. Friction Suspension reducer from PfP Industries can help generate viscosity with proper loadings. While it is challenging, PfP Industries friction suspension can be functional in most climate types.

versatility of friction reducers. Most friction reducers used are polyacrylamide-based, and can carry either an anionic, nonionic or cationic charge8. In most applications, anionic friction reducers are preferred due to their performance and cost relative to cationic friction reducers. As the salinity of the frac water increases, cationic
