Sentence examples for gas mobility control from inspiring English sources

Tsau et al. (1999) have used surfactant blends to improve gas mobility control in CO2 flooding.

This reflected the improvement in gas mobility control through increasing the amount of injected water.

The main objective of this research is to generate stable foam for gas mobility control using surfactant blend formulation.

The performed theoretical and experimental studies, pilot tests and field application showed that the foam used as gas mobility control can improve the EOR process.

Similar to polymer enhanced foam, viscosification is a means to increase foam stability, and thereby the effective viscosity of aqueous foams for gas mobility control.

Foam-generating surfactants flooding has been paid more attention in enhanced oil recovery (EOR) methods due to its unique properties of oil displacement and gas mobility control (Svorstol et al. 1996; Wang et al. 2009).

Foam is used during gas flooding such as with steam, CO2 and miscible gas for mobility control.

These reasons make viscoelastic surfactants attractive and practical for subsurface applications in the realm of matrix acidizing, conformance control (gel and foam treatment) and chemical enhanced oil recovery (fluid diversion and gas-flood mobility control).

Such rheological characterization would greatly advance our understanding of surfactant and foam transport in porous media with applications in fluid (gas and water) mobility control in gas enhanced oil recovery.

It can be deduced that the current EOR methods are a combination of gas and water (multiphase scheme), for mainly mobility control of the gas and improved gas injection efficiency.

Hence, gas channeling blocking and mobility control are important technical issues for the success of CO2 injection.
