  • What is a friction reducer (polyacrylamide)?
  • Due to the large volumes of water used, a friction reducer (polyacrylamide) is added to the fluid package to reduce the pumping energy required for the operation. The presence of the friction-reducing polymer (polyacrylamide) can reduce the friction loss and required pressures by as much as 60%.
  • What type of friction reducer is used in hydraulic fracturing?
  • In hydraulic fracturing fluids, high molecular weight (normally over 10 6 Da) polyacrylamide (PAM) (long chain polymer, linear structure) is the most commonly applied friction reducer with high water solubility and good thermal stability ( Xiong et al., 2018a; Yang et al., 2019 ).
  • What factors affect the performance of polyacrylamide-based friction reducers?
  • An important variable that highly affects the performance of polyacrylamide-based friction reducers is ion content. Performance, therefore, becomes dependent on both the ion type (cationic, anionic, monovalent or divalent) and the concentration present in the source water (Xu et al., 2016).
  • Can polyacrylamide friction reducers be used in slickwater fracturing?
