  • Can cationic polyacrylamide be used in oilfield wastewater treatment?
  • Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
  • Can cationic-surfactant polyacrylamide be used as a viscosifier in drilling fluid?
  • Likewise, Shettigar et al. (2018) designed a cationic-surfactant polyacrylamide as viscosifier in drilling fluid, which showed the improvement of rheology and cutting effect due to the hydrophobic and electrostatic interaction between the surfactant (cetyltrimethyl ammonium bromide) and polymer.
  • Is cationic polyacrylamide a good fluid additive?
  • It is recommended to use anionic polyacrylamide because of its minimal interaction and also compatibility with other fluid additives. Due to the cationic polyacrylamides interacting strongly with shale, it can potentially cause formation damage. Both the rheological studies and the zeta potential tests gave the same results.
  • Does cationic polyacrylamide interact with shale?
  • Zeta potential and rheological measurements were made to semi-quantify these interactions. Based on the studies, cationic polyacrylamide interacts with both the shales strongly even in the presence of salt and TMAC, whereas anionic polyacrylamide interacts less with the shales. Each type of shale analyzed interacts differently with polyacrylamide.
