  • 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.
  • Can gel be used as water shut-off agent?
  • The use of gel as the water shut-off agent has been widely reported in enhanced oil recovery (EOR) of mature oil fields. The organically cross-linked polymer systems are preferred due to their greater thermal stability and suitability over wide pH range.
  • 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.
