WebNov 1, 2011 · Polymer flood is the most widely used chemical EOR method. By adding polymers to water, the water–oil mobility is lowered. Such a change can lead to better sweep efficiency. It is generally believed that polymer flooding cannot reduce the residual oil saturation, but it can help to reach residual oil saturation in shorter time (Du and Guan … WebAssociating polymer (AP) is a new kind of polymer being used for polymer flooding. It contains acrylamide monomers and a small percentage of hydrophobic monomers 1% that attach to the polymer’s backbone during the polymerization process, as shown in Figure p7 (Zhou et al. 2007). Figure p7.
