Polyacrylamide

  • What is polyacrylamide (PAM)?
  • This chapter discusses polyacrylamides (PAM). Among the various polymers that have been studied for chemical enhanced oil recovery, PAM is most important. PAM is used frequently for mobility control as well as permeability control. PAM (and its modified forms) is the principal polymer used in significant amounts on a commercial basis.
  • What is next polyacrylamide hydrogel?
  • NEXT Polyacrylamide hydrogels are widely used as lost circulation materials and plugging agents in oil and gas production engineering. In these practical applications, controllable gelation time, favorable gel strength, and interface adhesion strength are desirable properties for polyacrylamide hydrogels.
  • Do cationic polyacrylamide hydrogels have a higher interface adhesion strength?
  • Interestingly, cationic polyacrylamide hydrogels possess a higher interface adhesion strength but less bulk cohesion. These findings are helpful to comprehend molecular weight and concentration effect on polyacrylamide hydrogel performances and the relationship between hydrogel network structure and macroscopical properties.
  • Why is the polyacrylamide (PAM) market declining?
  • North America The Polyacrylamide (PAM) market in North America during the fourth quarter of 2023 witnessed a declining trend, primarily due to reduced demand in key downstream industries such as industrial water treatment and the Oil & Gas Enhanced Oil Recovery (EOR) sector.
