Sentence examples for in mobility ratio from inspiring English sources
Thus, the decrease in mobility ratio greatly increase sweep efficiency.
Reduction in mobility ratio and IFT is influenced by reservoir brine salinity, reservoir temperature, concentration of chemical ingredients an oil components, and others [76, 77, 78, 79].
By evaluating the contact angle, it was observed that wettability alteration also might be involved in the oil displacement mechanism in this process together with reduction in mobility ratio and permeability to water that might divert injected fluid into unswept areas (bypassed oil) and enhance the oil recovery.
Reduction in mobility ratio and IFT is influenced by reservoir brine salinity, reservoir temperature, concentration of chemical ingredients and oil components, and others (Gaonkar 1992; Ferdous et al. 2012; Liu et al. 2008; Gong et al. 2009; Cao et al. 2012; Zhang et al. 2012).
The numerical study encompassed a wide range of horizontal wellbore lengths as well as three magnitudes in mobility ratios.
In this case, the governing mechanism would possibly be the decrease in the mobility ratio (oil to water viscosity) rather than the change in the oil-aqueous IFT because the oil-aqueous IFT showed a negative impact on the oil recovery (i.e. the oil-aqueous IFT increased as the nanofluids were added).
The reduction in the mobility ratio is achieved by increasing the viscosity of the aqueous phase.
The low density of CO2 gas relative to oil promotes gravity override, whereas low viscosity results in unfavorable mobility ratio leading to viscous fingering.
Figure 17 exhibits the cumulative oil production of various oil viscosities, and it is noticed that the sweep efficiency of pure brine flooding grows as the viscosity of oil viscosity decreases, due to the reduction in oil water mobility ratio.
This happens as a result of the low viscosity of the CO2 compared to the oil, and it results in an adverse mobility ratio.
Areal and vertical sweep efficiencies are in large measure determined by the mobility ratio in the displacement process.
