Polymer flooding

WebApr 11, 2024 · Polymer electrolyte membrane (PEM) fuel cells produce water as byproduct, which may cause electrode “flooding” and reduce cell performance. In operation, water usually builds up downstream in the gas flow channel due to the water production by the oxygen reduction reaction (ORR), leading to a water spatial distribution. http://large.stanford.edu/courses/2015/ph240/zerkalov2/docs/sino.pdf

WebCore-scale tertiary polymer flooding predictions revealed the positive effect of injection rate and polymer concentration on oil displacement efficiency. It was found that high polymer concentration (>2000 ppm) is needed to displace residual oil at reservoir rate as opposed to near injector well rate. WebInfluenced by water injection, a dominant flow channel is easily formed in the high water cut stage of a conglomerate reservoir, resulting in the inefficient or ineffective circulation of the injected water. With gel flooding as one of the effective development methods to solve the above problems, its parameter optimization determines its final development effect, … inch ins https://sullivanbabin.com
