...Zhibin An; Kang Zhou; Jian Hou; Dejun Wu; Yuping Pan; Shuai Liu A clear understanding of the main controlling factors for injection and production allocation of polymer flooding is the key to successful differential adjustment for well management in high water cut reservoirs. Generally, sensitivity...

...Marcelo E. N. Freire Filho; Rosangela B. Z. L. Moreno Polymer flooding is widely applied to enhance oil recovery in sandstone reservoirs. However, applications in carbonate formations are challenged by the possible high adsorption of anionic polymers such as polyacrylamides and xanthan gum. Non...

...Mingchen Ding; Yugui Han; Yefei Wang; Yigang Liu; Dexin Liu; Zhengtian Qu It is generally accepted that polymer flooding gets less effective as the heterogeneity of a reservoir increases. However, very little experimental information or evidence has been collated to indicate which levels...
