“…Furthermore, foam density variation decreases over time because of a reduction in the capillary‐based driving force of drainage, which means a decrease in the velocity of liquid between foam films (Figure ). Thus, considering the shear thinning behaviour of the polymeric solution presented in this study, the viscosity of foaming solution probably increases with the passing of time, which further decreases the drainage rate . Another parameter by which polymer may affect foam behaviour is steric repulsion.…”

The present study aims at monitoring the bulk and bubble-scale behaviour of anionic polyacrylamide-sodium dodecyl sulphate stabilized foam in the absence and presence of oil. Dynamic stability tests provided results indicating that polymer increases the foam dynamic stability and decreases the drainage. Oil slows down the drainage rate of polymer-surfactant foam. In the absence of oil, foam is drained gradually/smoothly whereas remarkable fluctuations are evident in drainage graphs when oil is present. The Hele-Shaw cell was employed to conduct bubble-scale as well as statistical analyses on how foam texture is influenced by a polymer-surfactant system and hydrocarbon. Bubble-scale analyses, taken right after foam generation in the absence of oil, revealed that foam bubble sizes and their standard deviation increase by polymer concentration. The coefficient of variation of foam bubble sizes drops with polymer concentration in the absence/presence of oil, meaning the growth of foam texture uniformity. Oil increases the bubble size diversity in the foam texture. Disproportionation/Ostwald ripening is hindered by increasing the foam bubble distribution uniformity by adding polymer to the foaming solution. At polymer concentrations higher than 13 Â 10 À4 g/g, a polymersurfactant mixture generates foam in the presence of oil as stable as foam in the absence of oil, while at the polymer concentrations lower than 7 Â 10 À4 g/g, bubbles are highly unstable when oil is present. Results of this study help to gain a better understanding about the extent to which polymer could enhance the foam stability in bulk/bubble-scale, which might be applicable for enhanced oil recovery operations.

“…So far, a lot of strong efforts have been paid to understand the reason of foam instability, to produce ultrastable foam [16][17][18][19][20]. Furthermore, understanding of foam rheology is conducive to the study of foam stabilization that has aroused increasing attention during the last decade [21][22][23][24][25]. However, the study of the shear rheological properties of foam has focused on shear viscosity and viscoelasticity [26][27][28].…”

Understanding of foam rheology is significant for the study of foam stabilization. In fact, the foam thixotropy is an important factor to foam stability, but the study about it has not attached great importance. Shear viscosity of different foam stabilizer solutions were investigated as well as microstructure, shear viscosity thixotropy, and stability of different foam systems prepared by the different foam stabilizers. The results show that high shear viscosity of foaming agent solution contributes to decreasing drainage of foam. Collapse of foam depends on the compact degree of molecular alignment. Reaction between the hydrophilic groups of foam stabilizer molecule and accessory ingredient molecule determines shear viscosity of foaming agent solution. Thixotropy of the foam can be used to evaluate the recoverability after sheared by high speed. Strong interaction forces and compact arrangement between the foam stabilizer molecule and accessory ingredient molecule contributes to improving stability and recoverability of foam. Foam stability increases with shear thixotropic recoverability of foam.
