Polymer flooding
WebDec 31, 2014 · Polymer flooding generally has been applied in light- or medium-gravity oil, and, even today, standard industry screening criteria limit its use to viscosities up to 150 cp. Pelican Lake is the site of the first successful application of polymer flooding in much-higher-viscosity oil (1,000–2,500 cp). WebThe fluid-flow mechanism of enhanced oil recovery (EOR) in porous media by alkali/surfactant/polymer (ASP) flooding is investigated by measuring the production performance, pressure, and saturation d

WebMar 6, 2006 · Daqing undertook its high-concentration polymer flood pilot in May 2003 after completing successful pilot injectivity tests of the high-concentration (1,500-2,000 ppm and 400-500 mPa-sec viscosity ... 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 …

WebApr 8, 2014 · We propose a mathematical model (numerical simulation) of surfactant-polymer flooding for a three-phase six-component system. The model takes into account various phenomena inherent to flooding, the effect of surfactant—polymer interactions on the viscosity, interfacial tension, and adsorption. We simulated the behavior of different … WebPolymer flooding belongs to chemical enhanced recovery; it is a well-known method (over 40 years of commercial application) with low risk and application over a wide range of …
WebPolymer flooding is an important enhanced oil recovery technol. introduced in field projects since the late 1960s. The key to a successful polymer flood project depends upon proper estn. of polymer retention. The aims of this paper are twofold. First, to show the mechanism of polymer flooding and how this mechanism is affected by polymer retention.
