  • Do charged polyacrylamides interact with shale?
  • Interaction of polymer-containing injected fluids with shale is a widely studied phenomenon, but much is still unknown about the interaction of charged polyacrylamides such as anionic and cationic polyacrylamides with shale.
  • Can cationic polyacrylamide rheologically quantify polymer–shale interaction?
  • In the cationic polyacrylamide medium, flocculation can result in excessive gravitational settling of the agglomerated shale particles. Hence, only the anionic polyacrylamide was used to rheologically quantify polymer–shale interaction. However, both cationic and anionic polyacrylamides were used to quantify polymer–shale zeta potential.
  • Does shale affect viscosity of polyacrylamide?
  • Usually the sample with highest viscosity is considered to have strong interaction of the bulk fluid with the shale particles, but in this case, the viscosity decreases after adding the shale to the polyacrylamide, i.e., polyacrylamides without shale have higher viscosity values at a given polyacrylamide concentration.
  • 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.
