  • Can nonionic polyacrylamide be used as a gel fracturing fluid?
  • Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.
  • What type of polyacrylamide is used in oil industry?
  • The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
  • What is an anionic polyacrylamide?
  • The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers . Both high- and low-molecular-weight polymers are used as drilling fluid additives.
  • Is DADMAC monomer a cationic polyacrylamide?
  • DADMAC monomer is inexpensive when compared to other cationic monomers used to make cationic polyacrylamides. However, due to the poor reactivity ratios between DADMAC and AMD, the polymers produced have low incorporation of the cationic monomer and are generally bimodal in their compositional distribution.
