Sentence examples for displacing efficiency from inspiring English sources

In a vertical heterogeneous reservoir, ASP flooding increases displacing efficiency by displacing residual oil through decreasing IFT and improving sweep efficiency.

Oil recovery can be greatly enhanced with the ASP (Alkali/Surfactant/Polymer) flooding technology by increasing sweeping efficiency and displacing efficiency.

ASP processes utilized the benefits of three flooding methods, whereby oil recovery was significantly enhanced, by decreasing IFT, increasing the capillary number, enhancing microscopic displacing efficiency and improving mobility ratio (Shen et al. 2009).

ASP flooding is a technique which is developed out on the basis of alkali flooding, surfactant flooding and polymer flooding (Wang et al. 2007) and oil recovery is enhanced gently by decreasing interfacial tension (IFT), increasing capillary number, enhancing microscopic displacing efficiency, improving mobility ration and increasing macroscopic sweep efficiency (Shen and Yu 2002).

Injection of polymer solutions would decrease the rate of increase of fractional water flow and extended the stable production period, so good displacing efficiency would be achieved.

This mechanism may also improve the microscopic displacement efficiency in displacing residual oil immobilized in the core by capillary forces and rock configuration (Wang et al. 2000).

Parameters like mobility ratio, volume of displaceable oil, volume of displaced oil and displacement efficiency have been obtained as results.

In the last decade, it has been proposed that polymer flooding can also increase the microscopic displacement efficiency by mobilizing and displacing residual oil saturation (trapped by capillary forces).

Microscopic or displacement efficiency refers to the displacement or mobilization of oil at the pore scale and measures the effectiveness of the displacing fluid in moving the oil at those places in the rock when the displacing fluid contacts the oil [41].

The magnitudes of the viscosity and density of displacing fluid relative to the displaced fluid are important design variables that affect volumetric displacement efficiency.

Gas is used in displacing oil for enhanced oil recovery because of its high microscopic-displacement efficiency.
