  • What is polyacrylamide polymer gel treatment?
  • They include polymer flooding, alkaline-surfactant flooding, foam flooding, gel treatments, and so on. Among these methods, polyacrylamide polymer gel treatment is a common and cost-effective method because the process can reduce water cut by sealing the thief zone and redistributing the water drive.
  • Can polyacrylamide gels be used in harsh environments?
  • Organically cross-linked PAM-related system To apply gel systems in harsh environments such as those with high temperatures, high salinity, and high pH, Chang et al. synthesized a polyacrylamide gels based on the cross-linking reaction between phenolic compounds (e.g., phenol and resorcinol) and formaldehyde.
  • What is a polymer gel system?
  • Many polymer gel systems have been developed to address various reservoir conditions, including temperature, the ionic composition and pH of formation water, the presence of either carbon dioxide or hydrogen sulfide, and the adsorption of chemicals on reservoir rock.
  • Can polymer gels reduce water production?
  • Polymer gels have been designed and successfully applied to improve sweep efficiency and to reduce excessive water production by minimizing reservoir heterogeneity.
