  • What is the concentration of anionic polyacrylamide and shale?
  • The concentration of the anionic polyacrylamide and shale was kept constant at 0.16 wt% and 0.5 lb/bbl, respectively. After taking the first reading, the sample was left undisturbed in the geometry for few hours before the next reading.
  • How does anionic polyacrylamide interact with shale?
  • The interaction of anionic polyacrylamide with the different shale samples was plotted as a function of anionic polyacrylamide concentration. The concentration of shale was kept constant at 0.5 lb/bbl, and the concentration of anionic polyacrylamide was varied from 0.1 to 0.2 wt%.
  • Does cationic polyacrylamide affect the surface properties of shale?
  • In this work, TMAC is compared with KCl and NaCl as an additive to anionic and cationic polyacrylamide systems for shale inhibition. In this work, the impact of anionic and cationic polyacrylamide in injected fluids on the alteration of the surface properties of shale is studied.
  • 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.
