Role of molecular parameters during flow of polymer solutions in unconsolidated porous media

Abstract: SynopsisIn order to understand the molecular behavior of polymers during flow through porous media, five polymers with varying degree of amide-carboxylate group ratio in partially hydrolyzed polyacrylamides were selected, and the flow properties of their dilute solutions were measured in unconsolidated porous media. It has been found that adsorption of the polymers a t the surface during flow, which plays an important role in permeability reduction, largely depends on the flexibility of the linear chains and e… Show more

“…This phenomenon is also known as the Residual Resistance Factor (RRF). One can interpret its effect as a reduction in the effective pore diameter, which can be caused by polymer adsorption or mechanical entrapment (Baijal and Dey, 1982;Dupuis et al, 2011). The RRF can be relevant even when small amounts of a polymer are retained (Jennings et al, 1971).…”
