Abstract Rheological properties of hydrolyzed polyacrylamide (HPAM) solutions were measured in oscillatory and flow shear. In oscillatory shear the storage and loss moduli increased as the concentrations of the solutions increased, but they decreased as salinity increased.,Nano-rheology of hydrogels using direct drive force … ,We measured the viscoelastic response of polyacrylamide hydrogels across a broad range of frequencies (0.1 Hz to 2 kHz) which enabled us to observe different mechanical regimes for hydrogels. Nanoscale measurements, were obtained via FD curves under slow loading (0.1 Hz to 10 Hz) and using a direct drive modulation technique (10 Hz to 2 kHz).,Effect of Surfactant and Hydrophobe Content on the … ,Associating polyacrylamide polymers have found profound use in the oil industry for Enhanced Oil Recovery (EOR) due to their improved rheological properties compared with ordinary non-associating polymers. Polymer rheology is important as it controls the mobility ratio of the displacing fluid to the displaced fluid and this can be severely affected by the high temperature and salinity present …
