  • Which acrylamide polymers are used in hydraulic fracturing?
  • Cationic, anionic, nonionic, and zwitterionic acrylamide polymers and copolymers can be synthesized as desired. Anionic PAM is the most widely used reducer with excellent DR performance and low cost for hydraulic fracturing of shale gas formations. Polyacrylamide FRs are generally provided in dry powder and emulsion.
  • Can surfactant improve fracturing performance of a polymer Fr?
  • As an additive, suitable surfactant can improve the salt-tolerant performance the of a polymer FR ( Seymour et al., 2018 ). Indeed, surfactant is usually used as an additive to reduce the capillary trap of the fluid in rock matrix to promote the flowback of fracturing fluids ( Jiang et al., 2013 ).
  • Which reducer is best for hydraulic fracturing?
  • Anionic PAM is the most widely used reducer with excellent DR performance and low cost for hydraulic fracturing of shale gas formations. Polyacrylamide FRs are generally provided in dry powder and emulsion. The dry powder facilitates transportation and storage, yet the emulsion dissolves faster.
  • Which additives improve slickwater fracturing performance?
  • FRs are also key additives that improve the performance of slickwater. Mitchell Energy Corporation successfully applied the slickwater fracturing technology in Barnett Shale for the first time in 1997.
