  • Polyacrylamide-Treated Kaolin clay: A Fabric Study

    Fabric changes in sedimentation, viscosity, and liquid limit behavior in the presence of polyacrylamide corresponding to the change in the type of particle association are observed in SEM. Floc/aggregate size and density tend to increase with increasing polyacrylamide concentration, showing the formation of more larger, denser flocs.

  • Effect of Specific Ions in Preparing Water on Viscosity

    Served as polymer flooding for the enhanced oil recovery, partially hydrolyzed polyacrylamide (PAM) has widely been employed for the oil production. The PAM solution prepared by the ground clean water was characterized with a higher viscosity in the early years while one, made by the oilfield produced water in the existence of complicated constituents, features a worse viscosity in the recent ...
