WebOct 14, 2024 · This is according to recently shared details of a 2-year-long polymer-flood project led by petroleum engineering researchers with the University of Alaska Fairbanks … WebJan 2, 2024 · In polymer flooding, polymer can be retained in porous media through precipitation, adsorption, or mechanical entrapment. As a result, formation damage can occur. Therefore, core flow tests should be conducted to examine the potential formation damage problems during polymer flooding processes prior to field application [ 18 , 19 ].

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. how many volts in 1 mv
First-Ever Polymer Flood in Alaska Hailed as a Heavy-Oil …
WebPolymer flooding is an enhanced oil recovery process in which a specific polymer concentration (usually 200–1500 ppm) is added to injected water. Polymers increase the viscosity of the injected solution and therefore preferably decrease the water to oil mobility ratio [ 1 ], which results in improving the displacement efficiency of the injected displacing … WebFeb 10, 2024 · Summary. Polymer flooding offers the potential to recover more oil from reservoirs but requires significant investments, which necessitate a robust analysis of economic upsides and downsides. Key uncertainties in designing a polymer flood are often reservoir geology and polymer degradation. The objective of this study is to understand … 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. how many volts do solar panels produce
